Hi,
We are migrating our ifrastructure from kvm+libvirt hypervisors to ovirt.
Everything is working fine but we're noticing that all the qemu-kvm
processes in the hypervisors take a lot of CPU.
The typical example is an idle machine, running top from the machine
itself it reports cpu use percentages below 10% and loads (with 2
processors) of 0.0x. The process running that machine in the hypervisor
rports cpu uses in the order of the 80-100%.
Should the values look like this? Why are the idle machines eating up so
much CPU time?
Thank you.
Xavier
