Subject: [ANNOUNCE] kvm-53 release
Date: Tue, 20 Nov 2007 11:03:28 +0200	[thread overview]
Message-ID: <4742A2E0.7000007@qumranet.com> (raw)

Most notable is that an fpu leak on AMD has been plugged.  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.
