[Xen-users] suspect cpu utilization level

["Marco Strullato" <marco.strullato@xxxxxxxxx>]

Hi all, I've a linux dom0, a dom1 winxp sp2 (WinXP) and another winxp sp2 with 2 vcpu (WinXP_02)
Dom2 uses all the dom0 idle: I mean this vm uses too much resources, it seems something wrong in configuration.

This is strange because the other win xp uses very few resources

I'll attach some useful output..

Suggestions?

I changed the xen scheduler giving more weight to WinXP_02 but it wasn't useful
