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. http://kvm.qumranet.com
