[ANNOUNCE] kvm-60 release

[ANNOUNCE] kvm-60 release

[Avi Kivity]

I'd hoped to release the first version of virtio guest drivers with 
kvm-60, but that is delayed, and enough changes have accumulated.  Most 
notable is virtio host support and Vista x64 on AMD hosts.

Changes from kvm-59:
- fix compilation with older kernels (Andi Kleen)
- virtio host support (Anthony Liguori, Dor Laor)
   - includes block and network devices
- fix power management timer overflow handling
- fix qemu running with older kernels
- boot from scsi/virtio (Anthony Liguori)
- add 1280x800 resolution to -std-vga
- fix acpi sci interrupt generation
- compile fixes (Carlo Marcelo Arenas Belon)
- update ide cdrom to match qemu (Carlo Marcelo Arenas Belon)
- fix extboot on older gcc (Christian Ehrhardt)
- powerpc dcr tests (Christian Ehrhardt)
- rtl8139 is now the default nic type (Guido Guenther)
- acpi power button support (Guido Guenther)
- powerpc testsuite harness (Hollis Blanchard)
- powerpc libkvm support (Jerone Young)
- bump piix4 to rev 3 to avoid slowdown reading pm timer (Marcelo Tosatti)
- migration updates (Uri Lublin)
- ia64 smp support in qemu (Xiantao Zhang)
- fix acpi vapic page on save/restore
- move x86 fpu to x86 specific header (Christian Ehrhardt)
- minor shadow code simplification(Eddie Dong)
- optimize pae pte updates (Eddie Dong, Eric Liu)
- simplify shadow hash table indexing (Eddie Dong)
- kvm_para.h compile fix (Glauber de Oliveira Costa)
- dirty page tracking fix (Izik Eidus)
- fix svm lazy fpu switching (Joerg Roedel)
   - fixes Vista x64 on AMD
- only allow vmcall/vmmcall on #UD traps (Sheng Yang)

Notes:
      If you use the modules bundled with kvm-60, you can use any version
of Linux from 2.6.17 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.

I missed:

  - fix unbounded latency due to a race in the guest entry code
    - with this fix and a realtime kernel, sub 50usec worst case 
latencies can be achieved
  - move apic timer migration to preemptible code


-- 
Any sufficiently difficult bug is indistinguishable from a feature.
