This actually fixed the problem, we now get all 24 CPUs: virsh # vcpuinfo 08867271-d458-43dc-8a03-807e83d107b4 VCPU: 0 CPU: 9 State: running CPU time: 1.3s CPU Affinity: yyyyyyyyyyyyyyyyyyyyyyyy To give you an example from the 'broken' host (still with 0.10.2): [root@host29 ~]# virsh vcpuinfo 17db9ebb-691b-47e1-bbf4-c9e3c1388d4f VCPU: 0 CPU: 3 State: running CPU time: 3103.2s CPU Affinity: yyyyyyyyyyyy VCPU: 1 CPU: 1 State: running CPU time: 3460.4s CPU Affinity: yyyyyyyyyyyy -- George-Cristian Bîrzan
