[Xen-users] High CPU utilization on converted domU's

[James Pifer <jep@xxxxxxxxxxxxxxxx>]

I have a few domU's that have been converted from standalone servers.
They are Windows 2000 servers. They run fine except for the CPU
utilization in xen. virt-manager shows 100% cou for the domU even though
inside the domU the CPU is 99% idle  according to Windows Task Manager. 

These domUs are running off image files. Any suggestions or settings I
should try?

xen version is xen-3.2.0_16718_18-0.3 on SLES10SP2 x64.

Current settings for on eof the domUs:
