[libvirt-users] Windows guest eats as many CPU as available

[Mike Ponomarenko]

For me it eats 10-20%, and I was not able to lower that (linux uses 0%).
And if I am not mistaken, it eats 100% when you have chosen wrong ACPI
parameters in domain.xml.
Take a look at https://bugs.launchpad.net/ubuntu/+source/virt-manager/+bug/228442
