Subject: [ANNOUNCE] kvm-30 release
Date: Thu, 19 Jul 2007 15:55:13 +0300 [thread overview]
Message-ID: <469F5F31.2030809@qumranet.com> (raw)
This kvm release introduces guest smp. I've tested 4-way Linux (64-bit
and 32-bit) and 2-way Windows XP. A kernel build on 2-way 64-bit Linux
is 40% faster that on a uniprocessor guest. Expect performance to
improve as the in-kernel apic work is merged and as we tune kvm for smp.
Changes from kvm-29:
- minor fixes and cleanups (Jeff Dike, Rusty Russell, me)
- kernel pio string write (Eddie Dong)
- guest smp kernel fixes
- rdmsr and wrmsr real mode emulation
- fix real mode shadow pages aliasing nx large page shadows
- enable guest smp in qemu
- fix external module installer
- revert ide enable changes that caused an I/O regression
Notes:
If you use the modules from kvm-30, 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.
Modules from Linux 2.6.22 and up will work with any kvm version from
kvm-22. Some features may only be available in newer releases.
