Avi Kivity [interview] announced significant performance improvements and support for running 32-bit Windows Vista as a guest within the latest release of KVM. Originally merged into the 2.6.20 mainline Linux kernel [story], KVM stands for Kernel-based Virtual Machine, "a full virtualization solution for Linux on x86 hardware containing virtualization extensions". Regarding the new release, Avi announced:

"The happy theme of today's kvm is the significant performance improvements, brought to you by a growing team of developers. I've clocked kbuild at within 25% of native. This release also introduces support for 32-bit Windows Vista."

The happy theme of today's kvm is the significant performance 
improvements, brought to you by a growing team of developers.  I've 
clocked kbuild at within 25% of native.  This release also introduces 
support for 32-bit Windows Vista.

Changes from kvm-21:
- Significant performance improvements (Anthony Liguori, Eddie Dong, 
Qing He, me)
- Fix longstanding bug: time runs at double speed on x86_64 Linux (Qing He)
- Windows Vista 32-bit support (Qing He, Jun Nakajima)
- Support for kvm abi 10 modules
- Minor updates

Notes:
   If you use the modules from kvm-22, you can use any version of Linux
from 2.6.9 upwards.
   If you use the modules from Linux 2.6.20, you need to use kvm-12.
   If you use the modules from Linux 2.6.21, you need to use kvm-17.

   API/ABI stability is planned for Linux 2.6.22.

kvm-22 had a nasty regression where rebooting a 64-bit Linux guest would
kill the host. This is fixed in kvm-23, and by way of amends, a few
other guest reboot issues have been fixed as well.

Changes from kvm-22:
- OpenBSD 4.1 i386 support (Matthew Gregan)
- Fix host and guest crashes on reboot

Notes:
If you use the modules from kvm-23, you can use any version of Linux
from 2.6.9 upwards.
If you use the modules from Linux 2.6.20, you need to use kvm-12.
If you use the modules from Linux 2.6.21, you need to use kvm-17.

API/ABI stability is planned for Linux 2.6.22.

Has anyone tried OS/2 (obviously in 32bit) under KVM? I'd be curious to give it a go, if it works.

Why don't you try?

Why don't you try it and then tell the rest uf us if it works or not?

Why don't you drop the attitude and presume that they're asking in case someone else has already tried it and thus avoiding wasting their time in doing so. The Linux community has enough issues with people doing the same thing independent of each other without you encouraging more such time wasting activities.

No, why don't you try

Running OS/2 is about as much fun as taking a cheese grater to your nuts.

Nope. ECommStation 1.2 immediately crashes the KVM session.

Is this the usual (aggressive) way for you people to interact with others?
