Package: libvirt-bin Version: 0.9.12.3-1 Severity: normal Hi,
I faced an issue while attempting to decrease the number of vcpus one of my guest runs on, from 2 to only 1. vcpu definition in my <domain> definition file: <vcpu placement='static'>2</vcpu> Although the following command (in virsh environnment): "setvcpus <domain> 1" issues the following output: "error: internal error got wrong number of vCPU pids from QEMU monitor. got 2, wanted 1" libvirt seems to take that request into account : virsh # vcpuinfo <domain> VCPU: 0 CPU: 1 State: running CPU time: 178909,3s CPU Affinity: yyy virsh # vcpucount <domain> maximum config 2 maximum live 2 current config 2 current live 1 While on the guest side a cat /proc/cpuinfo still gives back two cpu available. Unless I'm mistaken somewhere in my use of setvcpus, I think the previous command left my host/guest in an inconsistent state. The command setvcpus <domain> 2 runs flawlessy and gives me back a "consistent" output of vcpuinfo/vcpucount regarding the guest /proc/cpuinfo.
