Hi,
I am using Qemu-KVM-0.12.5
This is somewhat old. Try upgrading.
on Intel Xeon (Vt-x enabled) processors and
monitoring the system using htop on the host. On the processors that
are running Qemu-KVM I am seeing a 50/50 split between userspace and
guest ("gu:" in htop). I have pinned the vCPU qemu-kvm threads to
specific host CPUs using taskset. In the guest the CPUs are nearly
100% userspace in htop.
Does anyone have ideas on why this is? Is there a way I can get much
higher utilization for the guest virtual CPUs wrt the host?
Please build qemu with --disable-cpu-strip and run 'perf top' to see
what's going on.
