Title:
kvm brings Oneiric host to a grinding halt
Status in linux package in Ubuntu:
Invalid
Status in qemu-kvm package in Ubuntu:
Confirmed
Bug description:
I'm running a Windows7 guest in KVM via libvirt/virt-manager on a
Oneiric desktop 64-bit. Every once in a while (2-3 times a week,
sometimes daily) the CPU usage goes berserk and the host becomes very
unresponsive and unusable. This also happened once with a Breezy guest
so it's not strictly a Windows issue. I'm just seeing it more often
with Windows because that's what I run daily.
More information attached, let me know what other info I should collect, the
next time the machine is in that state.
