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)?

just to clarify, if i've a 4 core host cpus can i give 4 cpus for both of the 2 guests?

Yes, virtual CPUs are mapped to threads.
