Currently this has some performance impact; next release should restore performance while maintaining correctness. Changes from kvm-52: - testsuite: exit on end of test - batch mode for kvm_stat script - compile fixes (Carlo Marcelo Arenas Belon, Joe Perches) - portability (Jerone Young, Zhang Xiantao) - disable lazy fpu on AMD (Amit Shah) - should fix instability on AMD - will cause performance regression, fix in progress - x86 emulator: fix 'push r/m' emulation (Amit Shah) - register use reduction in vmx guest entry - infrastructure for per-vm stats - extends existing per-vcpu stats - add mmu, state switch, emulation statistics - use copy_{to,from}_user to access guest memory (Izik Eidus) - simplify access to guest page tables (Izik Eidus) - fix entry to real mode with segment bases beyond 1MB (Jan Kiszka) - finally kill last use of cr2 in emulator (Sheng Yang) Notes: If you use the modules bundled with kvm-53, you can use any version of Linux from 2.6.9 upwards. If you use the modules bundled with Linux 2.6.20, you need to use kvm-12. If you use the modules bundled with 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. For best performance, use Linux 2.6.23-rc2 or later as the host. http://kvm.qumranet.com ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
