Mac os x on virtualbox linux
It also installs network drivers called vboxnetflt and vboxnetadp which enable virtual machines to make more use of your computer's network capabilities and are needed for any virtual machine networking beyond the basic NAT mode. Since distributing driver modules separately from the kernel is not something which Linux supports well, the install process creates the modules on the system where they will be used. This usually means first installing software packages from the distribution which are needed for the build process. Normally, these will be the GNU compiler GCC , GNU Make make and packages containing header files for your kernel, as well as making sure that all system updates are installed and that the system is running the most up-to-date kernel included in the distribution.
The running kernel and the header files must be updated to matching versions. The following list includes some instructions for common distributions. For most of them you may want to start by finding the version name of your kernel, using the command uname -r in a terminal. The instructions assume that you have not changed too much from the original installation, particularly not installed a different kernel type.
If you have, then you will need to determine yourself what to set up. With Debian and Ubuntu-based distributions, you must install the correct version of the linux-headers , usually whichever of linux-headers-generic , linux-headers-amd64 , linux-headers-i or linux-headers-ipae best matches the kernel version name. Also, the linux-kbuild package if it exists. Basic Ubuntu releases should have the correct packages installed by default. On Fedora, Redhat, Oracle Linux and many other RPM-based systems, the kernel version sometimes has a code of letters or a word close to the end of the version name.
In this case, the package name is kernel-uek-devel or equivalent. If there is no such code, it is usually kernel-devel. If you suspect that something has gone wrong with module installation, check that your system is set up as described above and try running the following command, as root:. Oracle VM VirtualBox is available in a number of package formats native to various common Linux distributions. In addition, there is an alternative generic installer. The generic installer packages are built on EL5 systems and thus require reasonably old versions of glibc, such as version 2.
Download the appropriate package for your distribution. The following examples assume that you are installing to a bit Ubuntu Wily system. Use dpkg to install the Debian package,as follows:. The installer will also try to build kernel modules suitable for the current running kernel. If the build process is not successful you will be shown a warning and the package will be left unconfigured.
After correcting any problems, run the following command:. If a suitable kernel module was found in the package or the module was successfully built, the installation script will attempt to load that module. Once Oracle VM VirtualBox has been successfully installed and configured, you can start it by clicking VirtualBox in your Start menu or from the command line. Creates a new system group called vboxusers. The installer must be executed as root with either install or uninstall as the first parameter.
For example:. Or if you do not have the sudo command available, run the following as root instead:. Either use the GUI user management tools or run the following command as root:. The usermod command of some older Linux distributions does not support the -a option, which adds the user to the given group without affecting membership of other groups.
In this case, find out the current group memberships with the groups command and add all these groups in a comma-separated list to the command line after the -G option. For example: usermod -G group1,group2,vboxusers username. Run the installer as follows:. This will unpack all the files needed for installation in the directory install under the current directory. To build the module, change to the directory and use the following command:.
If everything builds correctly, run the following command to install the module to the appropriate module directory:. In case you do not have sudo, switch the user account to root and run the following command:. The above make command will tell you how to create the device node, depending on your Linux system. On certain Linux distributions, you might experience difficulties building the module. You will have to analyze the error messages from the build system to diagnose the cause of the problems.
In general, make sure that the correct Linux kernel sources are used for the build process. Next, you install the system initialization script for the kernel module and activate the initialization script using the right method for your distribution, as follows:.
Installing Mac OS X Virtual Machine on VirtualBox
The Debian packages will request some user feedback when installed for the first time. The debconf system is used to perform this task. To prevent any user interaction during installation, default values can be defined. A file vboxconf can contain the following debconf settings:. The first line enables compilation of the vboxdrv kernel module if no module was found for the current kernel. The second line enables the package to delete any old vboxdrv kernel modules compiled by previous installations.
VirtualBox older builds The binaries in this section for VirtualBox before version 4. Source code Browse the source code repository This is the current development code, which is not necessarily stable. The default folder location is shown. The supported OSes are grouped. If you want to install something very unusual that is not listed, select Other. This is particularly important for bit guests.
It is therefore recommended to always set it to the correct value. The amount of memory given here will be taken away from your host machine and presented to the guest OS, which will report this size as the virtual computer's installed RAM. Choose this setting carefully. The memory you give to the VM will not be available to your host OS while the VM is running, so do not specify more than you can spare. If you run two VMs at the same time, even more memory will be allocated for the second VM, which may not even be able to start if that memory is not available.
On the other hand, you should specify as much as your guest OS and your applications will require to run properly. Otherwise you may cause your host OS to excessively swap out memory to your hard disk, effectively bringing your host system to a standstill. As with the other settings, you can change this setting later, after you have created the VM. This file represents an entire hard disk then, so you can even copy it to another host and use it with another Oracle VM VirtualBox installation.
To create a new, empty virtual hard disk, click the Create button. You can pick an existing disk image file. The drop-down list presented in the window lists all disk images which are currently remembered by Oracle VM VirtualBox. These disk images are currently attached to a virtual machine, or have been attached to a virtual machine. Alternatively, click on the small folder icon next to the drop-down list.
In the displayed file dialog, you can click Add to select any disk image file on your host disk. Click the Create button. This wizard helps you to create a new disk image file in the new virtual machine's folder. A dynamically allocated file will only grow in size when the guest actually stores data on its virtual hard disk.

It will therefore initially be small on the host hard drive and only later grow to the size specified as it is filled with data. A fixed-size file will immediately occupy the file specified, even if only a fraction of the virtual hard disk space is actually in use. While occupying much more space, a fixed-size file incurs less overhead and is therefore slightly faster than a dynamically allocated file.
To prevent your physical hard disk from running full, Oracle VM VirtualBox limits the size of the image file. Still, it needs to be large enough to hold the contents of your OS and the applications you want to install. For a modern Windows or Linux guest, you will probably need several gigabytes for any serious use.
After having selected or created your image file, click Next to go to the next page.

Click Create , to create your new virtual machine. The virtual machine is displayed in the list on the left side of the VirtualBox Manager window, with the name that you entered initially. After becoming familiar with the use of wizards, consider using the Expert Mode available in some wizards. Where available, this is selectable using a button, and speeds up the process of using wizards. Go to the VirtualBox VMs folder in your system user's home directory. Find the subdirectory of the machine you want to start and double-click on the machine settings file.
This file has a. Starting a virtual machine displays a new window, and the virtual machine which you selected will boot up. Everything which would normally be seen on the virtual system's monitor is shown in the window. In general, you can use the virtual machine as you would use a real computer. There are couple of points worth mentioning however. This wizard helps you to select an installation medium. Since the VM is created empty, it would otherwise behave just like a real computer with no OS installed. It will do nothing and display an error message that no bootable OS was found.
In the wizard's drop-down list of installation media, select Host Drive with the correct drive letter. In the case of a Linux host, choose a device file. This will allow your VM to access the media in your host drive, and you can proceed to install from there. If you have downloaded installation media from the Internet in the form of an ISO image file such as with a Linux distribution, you would normally burn this file to an empty CD or DVD and proceed as described above.
In this case, the wizard's drop-down list contains a list of installation media that were previously used with Oracle VM VirtualBox. If your medium is not in the list, especially if you are using Oracle VM VirtualBox for the first time, click the small folder icon next to the drop-down list to display a standard file dialog. Here you can pick an image file on your host disks. After completing the choices in the wizard, you will be able to install your OS. If you are running a modern guest OS that can handle such devices, mouse support may work out of the box without the mouse being captured as described below.
But unless you are running the VM in full screen mode, your VM needs to share keyboard and mouse with other applications and possibly other VMs on your host. After installing a guest OS and before you install the Guest Additions, described later, either your VM or the rest of your computer can "own" the keyboard and the mouse. Both cannot own the keyboard and mouse at the same time.
You will see a second mouse pointer which is always confined to the limits of the VM window. You activate the VM by clicking inside it. By default, this is the right Ctrl key on your keyboard. On a Mac host, the default Host key is the left Command key. The current setting for the Host key is always displayed at the bottom right of your VM window. Your keyboard is owned by the VM if the VM window on your host desktop has the keyboard focus. If you have many windows open in your guest OS, the window that has the focus in your VM is used.
This means that if you want to enter text within your VM, click on the title bar of your VM window first. To release keyboard ownership, press the Host key. As explained above, this is typically the right Ctrl key. Note that while the VM owns the keyboard, some key sequences, such as Alt-Tab, will no longer be seen by the host, but will go to the guest instead.
After you press the Host key to reenable the host keyboard, all key presses will go through the host again, so that sequences such as Alt-Tab will no longer reach the guest. For technical reasons it may not be possible for the VM to get all keyboard input even when it does own the keyboard. Your mouse is owned by the VM only after you have clicked in the VM window. The host mouse pointer will disappear, and your mouse will drive the guest's pointer instead of your normal mouse pointer. Note that mouse ownership is independent of that of the keyboard.
Even after you have clicked on a titlebar to be able to enter text into the VM window, your mouse is not necessarily owned by the VM yet. Most importantly, the Additions will get rid of the second "guest" mouse pointer and make your host mouse pointer work directly in the guest. OSes expect certain key combinations to initiate certain procedures. Some of these key combinations may be difficult to enter into a virtual machine, as there are three candidates as to who receives keyboard input: the host OS, Oracle VM VirtualBox, or the guest OS.
Which of these three receives keypresses depends on a number of factors, including the key itself. Host OSes reserve certain key combinations for themselves. As the X server intercepts this combination, pressing it will usually restart your host graphical user interface and kill all running programs, including Oracle VM VirtualBox, in the process. If, instead, you want to send these key combinations to the guest OS in the virtual machine, you will need to use one of the following methods:.
Use the items in the Input , Keyboard menu of the virtual machine window. The latter will only have an effect with Linux or Oracle Solaris guests, however. This menu also includes an option for inserting the Host key combination. Use special key combinations with the Host key, normally the right Control key. Oracle VM VirtualBox will then translate these key combinations for the virtual machine:. For some other keyboard combinations such as Alt-Tab to switch between open windows, Oracle VM VirtualBox enables you to configure whether these combinations will affect the host or the guest, if a virtual machine currently has the focus.
This is a global setting for all virtual machines and can be found under File , Preferences , Input.
While a virtual machine is running, you can change removable media in the Devices menu of the VM's window. But as the Settings dialog is disabled while the VM is in the Running or Saved state, the Devices menu saves you from having to shut down and restart the VM every time you want to change media. You can resize the virtual machine's window when it is running. In that case, one of the following things will happen:.
If you have scaled mode enabled, then the virtual machine's screen will be scaled to the size of the window. This can be useful if you have many machines running and want to have a look at one of them while it is running in the background. Alternatively, it might be useful to enlarge a window if the VM's output screen is very small, for example because you are running an old OS in it. The aspect ratio of the guest screen is preserved when resizing the window. To ignore the aspect ratio, press Shift during the resize operation. If you have the Guest Additions installed and they support automatic resizing , the Guest Additions will automatically adjust the screen resolution of the guest OS.
For example, if you are running a Windows guest with a resolution of x pixels and you then resize the VM window to make it pixels wider, the Guest Additions will change the Windows display resolution to x Otherwise, if the window is bigger than the VM's screen, the screen will be centered. If it is smaller, then scroll bars will be added to the machine window. When you click on the Close button of your virtual machine window, at the top right of the window, just like you would close any other window on your system, Oracle VM VirtualBox asks you whether you want to save or power off the VM.
Save the machine state: With this option, Oracle VM VirtualBox freezes the virtual machine by completely saving its state to your local disk.
MacOS VirtualBox VM on Ubuntu
When you start the VM again later, you will find that the VM continues exactly where it was left off. All your programs will still be open, and your computer resumes operation. Saving the state of a virtual machine is thus in some ways similar to suspending a laptop computer by closing its lid. Send the shutdown signal. This will send an ACPI shutdown signal to the virtual machine, which has the same effect as if you had pressed the power button on a real computer.
Power off the machine: With this option, Oracle VM VirtualBox also stops running the virtual machine, but without saving its state. This is equivalent to pulling the power plug on a real computer without shutting it down properly. If you start the machine again after powering it off, your OS will have to reboot completely and may begin a lengthy check of its virtual system disks. As a result, this should not normally be done, since it can potentially cause data loss or an inconsistent state of the guest system on disk.
In that case, powering off the machine will not disrupt its state, but any changes made since that snapshot was taken will be lost. The Discard button in the VirtualBox Manager window discards a virtual machine's saved state. This has the same effect as powering it off, and the same warnings apply. VM groups enable the user to create ad hoc groups of VMs, and to manage and perform functions on them collectively, as well as individually.
Select multiple VMs and select Group from the right-click menu. This command creates a group "TestGroup" and attaches the VM "vm01" to that group. Detach a VM from the group, and delete the group if empty. For example:. This command detaches all groups from the VM "vm01" and deletes the empty group. This command creates the groups "TestGroup" and "TestGroup2", if they do not exist, and attaches the VM "vm01" to both of them. With snapshots, you can save a particular state of a virtual machine for later use.
At any later time, you can revert to that state, even though you may have changed the VM considerably since then. A snapshot of a virtual machine is thus similar to a machine in Saved state, but there can be many of them, and these saved states are preserved. To see the snapshots of a virtual machine, click on the machine name in VirtualBox Manager. Then click the List icon next to the machine name, and select Snapshots.
Until you take a snapshot of the machine, the list of snapshots will be empty except for the Current State item, which represents the "now" point in the lifetime of the virtual machine. Take a snapshot.
This makes a copy of the machine's current state, to which you can go back at any given time later. The snapshots window is shown. Do one of the following:. Click the Take icon. Right-click on the Current State item in the list and select Take. In either case, a window is displayed prompting you for a snapshot name. This name is purely for reference purposes to help you remember the state of the snapshot. For example, a useful name would be "Fresh installation from scratch, no Guest Additions", or "Service Pack 3 just installed".
You can also add a longer text in the Description field. Your new snapshot will then appear in the snapshots list. Underneath your new snapshot, you will see an item called Current State , signifying that the current state of your VM is a variation based on the snapshot you took earlier. If you later take another snapshot, you will see that they are displayed in sequence, and that each subsequent snapshot is derived from an earlier one.
Oracle VM VirtualBox imposes no limits on the number of snapshots you can take. The only practical limitation is disk space on your host. Each snapshot stores the state of the virtual machine and thus occupies some disk space. Restore a snapshot. In the list of snapshots, right-click on any snapshot you have taken and select Restore. By restoring a snapshot, you go back or forward in time.
The current state of the machine is lost, and the machine is restored to the exact state it was in when the snapshot was taken. Restoring a snapshot will affect the virtual hard drives that are connected to your VM, as the entire state of the virtual hard drive will be reverted as well. This means also that all files that have been created since the snapshot and all other file changes will be lost.
In order to prevent such data loss while still making use of the snapshot feature, it is possible to add a second hard drive in write-through mode using the VBoxManage interface and use it to store your data. As write-through hard drives are not included in snapshots, they remain unaltered when a machine is reverted. To avoid losing the current state when restoring a snapshot, you can create a new snapshot before the restore operation.
By restoring an earlier snapshot and taking more snapshots from there, it is even possible to create a kind of alternate reality and to switch between these different histories of the virtual machine. This can result in a whole tree of virtual machine snapshots, as shown in the screenshot above. Delete a snapshot. This does not affect the state of the virtual machine, but only releases the files on disk that Oracle VM VirtualBox used to store the snapshot data, thus freeing disk space.
To delete a snapshot, right-click on the snapshot name in the snapshots tree and select Delete. Snapshots can be deleted even while a machine is running. Whereas taking and restoring snapshots are fairly quick operations, deleting a snapshot can take a considerable amount of time since large amounts of data may need to be copied between several disk image files.
Temporary disk files may also need large amounts of disk space while the operation is in progress. There are some situations which cannot be handled while a VM is running, and you will get an appropriate message that you need to perform this snapshot deletion when the VM is shut down. Think of a snapshot as a point in time that you have preserved. More formally, a snapshot consists of the following:. The snapshot contains a complete copy of the VM settings, including the hardware configuration, so that when you restore a snapshot, the VM settings are restored as well. For example, if you changed the hard disk configuration or the VM's system settings, that change is undone when you restore the snapshot.
The copy of the settings is stored in the machine configuration, an XML text file, and thus occupies very little space. The complete state of all the virtual disks attached to the machine is preserved.
