[ANNOUNCE] kvm-34 release

[ANNOUNCE] kvm-34 release

[Avi Kivity]

Many changes; most notable is that kvm is now preemptible.  This is not 
directly user-visible, but is a benefit for embedded/realtime users and 
is a first step on the road to swapping guest pages to disk.

Note that due to that change, running on a host earlier than Linux 
2.6.23-rc2 will experience a slight performance degradation.

Changes from kvm-33:
- make kvm preemptible
- allow calling sleeping functions in the kvm exit handlers (Shaohua Li)
   - this is a first step in getting guest swapping
- fix running kvm on nx-incapable host kernel on nx-capable hardware
- fix more fallback from the x86 emulator writeback changes (Aurelien 
Jarno, me)
- remove vmx specific code from subarch independent code (Gregory Haskins)
- allocate vcpus as needed (Rusty Russell)
- consolidate x86 emulator guest read/write code (Laurent Vivier)
- cleanup string pio instruction emulation (Laurent Vivier)
- ensure all cpus have the same vmx features (Sheng Yang)
- version string for external module
- disable long mode capability bit on 32-bit kernels
- fix qemu -isapc (Uri Lublin)
- fixes for smp live migration
   - this is still raw
- fix unhandled wrmsr MSR_CSTAR on i386 (Luca Tettamanti)
- some migration fixes (Jim Paris)
- the usual cleanups and minor fixes (various but mostly Rusty)


Notes:
    If you use the modules from kvm-34, 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.

Er, some parts of this are still on the laptop.  So it will only work 
with kvm-35.
