16.7 Legacy Series / Re: KVM, high cpu-usage.
« on: October 21, 2016, 01:19:47 am »
Hi,
I have the exact same issue. Running debian with kvm/libvirt (kernel 4.7 backports) and the host cpu is always around 30-60% when the vm is/should be idle. Host load average is: 0.48, 0.65, 0.95.
I'm using virtio/virtnet. Host CPU is AMD x86_64.
Do you have any ideas or new finding in the meantime?
The only thing I could found are some other reports, indicating that it might be a general freebsd on kvm issue:
