Windows Server 2003 R2 SP2 does not run with more than 2 VCPUs

Windows Server 2003 R2 SP2 does not run with more than 2 VCPUs

[Julian Pawlowski]

Hi,

Just installed a new VM with W2k3 R2 SP1 and updated to the new SP2.
After the reboot the machine hangs right while the bootscreen appears.

My current VM configuration had 4 VPCUs with acpi=1 and apic=1 and SP1
worked great. With SP2 I can only boot with a maximum of 2 VCPUs now.

Maybe M$ changed something with their HAL in SP2 so that Xen needs a patch
for it now.


Cheers,
Julian

I hadn't realised this was released yet. We'll be testing it out asap I'm
sure. It'd be nice to have a fix for 3.0.5 in a couple of weeks time.

Actually we already test with SP2. What version of Xen are you using?

I'm currently working with Xen 3.0.4 installed from the Novell Xen preview
program (SLES10-x86-64-changeset13138-15.tar.bz2 from 2007-03-14) on SUSE
Linux 10.1.

Can I do something for you to help to debug that phenomenon?

There are a number of ACPI fixes in xen-unstable (soon to be 3.0.5). You
might want to try installing Xen and tools from the xen-unstable repository
(I doubt there's a conveniently packaged version available for SLES).

Hi,Julian

I could not reproduce your prolem.
After update a Win 2003 R2 SP1 guest to SP2, I still can boot it with 4 vcpus.


Thanks
Yunfeng
