kvm in karmic: smp win2003 guests crash on reboot

[gaestur]

Binary package hint: kvm

As bug 341979 is marked as "Fix released" I'm filing a new bug:

Found the same problem with rebooting SMP windows guests in Karmic:

Test site: HP DL 380 G5 (8-core, 16 GB RAM).
qemu-kvm 0.11.0-0ubuntu6.3
Linux net-v2 2.6.31-20-server #57-Ubuntu SMP Mon Feb 8 09:59:59 UTC 2010 x86_64 GNU/Linux

Windows 2003 R2 guests are having the following problem with 2 virt CPU setup - first they crash during reboot after installation completion, then randomly crashing on consequent reboots. Shutdown ans manual startup work quite fine.

This will help us to find and resolve the problem.

I witnessed this bug only on one host (and it's the only host I'm using for kvm right now).
Host configuration is as follows:
Test site: HP DL 380 G5 (8-core, 16 GB RAM).
qemu-kvm 0.11.0-0ubuntu6.3
Linux net-v2 2.6.31-20-server #57-Ubuntu SMP Mon Feb 8 09:59:59 UTC 2010 x86_64 GNU/Linux

The trouble was faced with virtual machines running 32-bit Windows Server Enterprise 2003 R2. Tests for other Windows versions were not done. The problem was appearing no matter if current updates were applied to guest OS. Other guest OS (64-bit Fedora12 and FreeDSD 8) were running and rebooting well in the same two-processor configuration.
The bug reproduced itself on several virtual machines.

Windows virtual machines with single processor showed no evidence of this bug and were running fine under heavy load, that's why I suspect it's related to older bug 341979.
