For the write operations from the VM, a second, differencing image file is created which receives only the changes to the original image. While you can attach the same normal image to more than one virtual machine, only one of these virtual machines attached to the same image file can be executed simultaneously, as otherwise there would be conflicts if several machines write to the same image file.

Write-through hard disks are completely unaffected by snapshots. Their state is not saved when a snapshot is taken, and not restored when a snapshot is restored. Shareable hard disks are a variant of write-through hard disks. In principle they behave exactly the same.

The difference only shows if you attach such disks to several VMs. Shareable disks may be attached to several VMs which may run concurrently. This makes them suitable for use by cluster filesystems between VMs and similar applications which are explicitly prepared to access a disk concurrently.

Only fixed size images can be used in this way, and dynamically allocated images are rejected. This is an expert feature, and misuse can lead to data loss, as regular filesystems are not prepared to handle simultaneous changes by several parties. Immutable images only remember write accesses temporarily while the virtual machine is running. All changes are lost when the virtual machine is powered on the next time. As a result, as opposed to Normal images, the same immutable image can be used with several virtual machines without restrictions.

Creating an immutable image makes little sense since it would be initially empty and lose its contents with every machine restart. You would have a disk that is always unformatted when the machine starts up. Instead, you can first create a normal image and then later mark it as immutable when you decide that the contents are useful. If you take a snapshot of a machine with immutable images, then on every machine power-up, those images are reset to the state of the last current snapshot, instead of the state of the original immutable image.

As a special exception, immutable images are not reset if they are attached to a machine in a saved state or whose last snapshot was taken while the machine was running.

This is called an online snapshot. To reenable the automatic resetting of such images, delete the current snapshot of the machine. Oracle VM VirtualBox never writes to an immutable image directly at all. All write operations from the machine are directed to a differencing image. The next time the VM is powered on, the differencing image is reset so that every time the VM starts, its immutable images have exactly the same content.

The differencing image is only reset when the machine is powered on from within Oracle VM VirtualBox, not when you reboot by requesting a reboot from within the machine. This is also why immutable images behave as described above when snapshots are also present, which use differencing images as well.

If the automatic discarding of the differencing image on VM startup does not fit your needs, you can turn it off using the autoreset parameter of VBoxManage modifymedium. Multiattach mode images can be attached to more than one virtual machine at the same time, even if these machines are running simultaneously. For each virtual machine to which such an image is attached, a differencing image is created. As a result, data that is written to such a virtual disk by one machine is not seen by the other machines to which the image is attached.

Each machine creates its own write history of the multiattach image. Technically, a multiattach image behaves identically to an immutable image except the differencing image is not reset every time the machine starts. This mode is useful for sharing files which are almost never written, for instance picture galleries, where every guest changes only a small amount of data and the majority of the disk content remains unchanged.

The modified blocks are stored in differencing images which remain relatively small and the shared content is stored only once at the host. The following scenario illustrates the differences between the various image modes, with respect to snapshots. Assume you have installed your guest OS in your VM, and you have taken a snapshot. Later, your VM is infected with a virus and you would like to go back to the snapshot. With a normal hard disk image, you simply restore the snapshot, and the earlier state of your hard disk image will be restored as well and your virus infection will be undone.

With an immutable hard disk, all it takes is to shut down and power on your VM, and the virus infection will be discarded. With a write-through image however, you cannot easily undo the virus infection by means of virtualization, but will have to disinfect your virtual machine like a real computer.

Saneman1 Aug 19 Mondele Apr 6 What can be said has mostly been said, but I’ll chime in. It’s not quite as nice to configure as Parallels, but once it’s running it’s fantastic. Two-way clipboard support just works, and the granular control over the emulated hardware how many cores, how much RAM, what size drive, etc. I triple boot on my MacBook, but may toss that for using virtualized PCs.

It works well with most Linuxes I throw at it have had some issues with Linux Mint and video drivers. It works well with Windows. Parallels seems to virtualize Mac OS more smoothly. I sometimes wonder if VMWare Fusion would be worth it, for the raw device support, etc.

In short, it does so much of what I need it to do that the commercial competitors don’t have an appeal for me. I may, eventually, see if qemu is faster, but that’s even more arcane, so it’s not likely in the short term. Great free virtual machine. I was using it and vmware workstation.

By Malcolm Owen 2 hours ago. Dynamic resolution support also makes it easier for users to change the size of Windows, including quick changing of resolutions, and faster booting and rebooting speeds also touted. If all you’re doing is running one important outdated app, this will probably do the trick.
