Hello,

is there a solution for that problem? I'm experiencing the same problems ever
since I installed SBS 2008 on KVM.

I was running the host with Ubuntu 10.04 but upgraded to 10.10 - mainly because
of performance problems which were solved by the upgrade.

After the upgrade the system became extremly unstable. It was crashing as soon
as disk io and network io load was growing. 100% reproduceable with windows
server backup to an iscsi volume.

i had virtio drivers for storage and network installed (redhat/fedora 1.1.11).
At each BSOD I had the following line in the log of the guest:

virtio_ioport_write: unexpected address 0x13 value 0x1

I changed the network interface back to e1000. What I experience now (and I had
that a the very beginning before i switched to virtio network) are freezes. The
guest doesn't respond anymore (doesn't answer to pings and doesn't interact via
mouse/keyboard anymore). Host CPU usage of the kvm process is 100% on as many
cores as there are virtual cpus (in this case 4).

I'm a bit frustrated about this. I have 2 windows 2003 32bit, 1 windows xp and 3
linux guests (2x 32bit, 1x64 bit). They are all running without any problems
(except that the windows xp guest cannot boot without an ntldr cd image). Only
the SBS2008 guest regulary freezes.

The host system has 2 Intel Xeon 5504, Intel Chipset 5500, Adaptec Raid 5805, 24
GB DDR3 RAM.

I know there is a lack of detailed information right now. I first need to know
if anybody is working on this or has similar problems. I can deliver minidumps,
and any debugging information you need.

I don't want to give up now. We will switch to Hyper-V if we cannot solve this,
because we need a stable virtualization plattform for Windows Guests. I would
like to use KVM it is so much more flexibel.

Best regards
Manfred
