[ANNOUNCE] kvm-40 release

[ANNOUNCE] kvm-40 release

[Avi Kivity]

Not a lot of progress, but still worthy of a release.  Reboot mostly 
works, with the notable exception of Windows with the ACPI HAL, running 
with in-kernel irqchip.

Changes since kvm-39:
- fix guest reboot (most scenarios)
- further x86 emulator work (Nitin A Kamble)
- compile fixes for older kernels
- make the external module work again

Notes:
    If you use the modules bundled with kvm-40, 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.

i've try kvm-40 it now on centos-5 with kernel-2.6.18-8.1.10.el5 x86_64
host (8gb ram and 4 core) and one centos-5 x86_64, centos-5 i386,
mandrake i586 guests. i try to give 4 cpu for the first 2 guest and 1
cpu for the last. after i start these 3 guests the host kernel crash all
the time after the guest starts to boot. so i now try to switchback to
kvm-36.

It will be helpful to provide the oops/dmesg output.

how? write it down with paper from the console? at the same time there's
just a kernel stack dump and i can't scroll it up (eg with shift-page up).

A photo will do, but it's possible that the most interesting part has
been scrolled off screen. Can you setup a serial console
(Documentation/serial-console.txt) or at least netconsole
(Documentation/networking/netconsole.txt)?

Yes, virtual CPUs are mapped to threads.

I don't know if someone can reproduce a problem I'm having. When I run the
windows xp service pack 2 update with kvm-40 it always crashes and after I'm
unable to boot virtual machine resulting in blue screen.
