Which virtual machines exist for Linux besides VirtualBox? [closed]

You can use for example qemu + kquemu acceleration, but VirtualBox is easier.

And you can also install VMWare (for example, VMWare server )

I think most popular virtual machines for Linux are:

• KVM (Kernel Based Virtual Machine). I guess it's also the fastest VM for Linux.
• QEMU
• Xen

There is also a GUI for manage all these VMs - Virtual Machine Manager.

VMWare is available for Linux.

As far as I remember, the server and player versions cost nothing, but the workstation does have a price.

I have only used VMWare on Windows (and that was a while ago), where I found that it considerably slowed down boot times etc. I find that Virtualbox is much better, and have (rather lazily) just used it on Linux rather than bother trying VMWare.

There is also bochs that you could have a look at as well as qemu.

If you do try the others, perhaps you could report back on how they compare: I must admit that I've basically ignored the non-Virtualbox options for quite a while.

Another option is XEN:

The Xen® hypervisor, the powerful open source industry standard for virtualization, offers a powerful, efficient, and secure feature set for virtualization of x86, x86_64, IA64, ARM, and other CPU architectures. It supports a wide range of guest operating systems including Windows®, Linux®, Solaris®, and various versions of the BSD operating systems.
