Could reporduce it on RHEL6.5 with following packages: qemu-kvm-rhev-0.12.1.2-2.415.el6_5.3.x86_64 libvirt-client-0.10.2-29.el6_5.2.x86_64 libvirt-0.10.2-29.el6_5.2.x86_64 qemu-guest-agent-0.12.1.2-2.415.el6.x86_64 The step is same with bug description, and the result shows below: [root@red01 images]# virsh dumpxml rhel6u5_qcow2 | grep vcpu <vcpu placement='static' current='1'>3</vcpu> [root@red01 images]# virsh setvcpus rhel6u5_qcow2 --guest 2 error: internal error guest agent reports less cpu than requested [root@red01 images]# virsh setvcpus rhel6u5_qcow2 --guest error: command 'setvcpus' requires --count option [root@red01 images]# virsh vcpucount rhel6u5_qcow2 --guest 1 Fixed upstream:

qemu: Improve error when setting invalid count of vcpus via agent
https://bugzilla.redhat.com/show_bug.cgi?id=1035108
When attempting to enable more vCPUs in the guest than is currently
enabled in the guest but less than the maximum count for the VM we
currently reported an unhelpful message:
error: internal error: guest agent reports less cpu than requested
This patch changes it to:
error: invalid argument: requested vcpu count is greater than the count
of enabled vcpus in the domain: 3 > 2
This bug is fixed in latest libvirt-0.10.2-32.el6, the verification steps are below:
# virsh dumpxml r6 | grep cpu -A 3
<vcpu placement='auto' current='3'>5</vcpu>
<numatune>
<memory mode='strict' placement='auto'/>
</numatune>
# virsh setvcpus r6 4 --guest
error: invalid argument: requested vcpu count is greater than the count of enabled vcpus in the domain: 4 > 3
# virsh vcpucount r6 --guest
3
# virsh setvcpus r6 2 --guest
# virsh vcpucount r6 --guest
2
# virsh setvcpus r6 -1 --guest
error: Invalid number of virtual CPUs
# virsh setvcpus r6 99999 --guest
error: numerical overflow: input too large: 99999
# virsh setvcpus r6 9999 --guest
error: invalid argument: requested vcpus is greater than max allowable vcpus for the domain: 9999 > 5
And I change the status to VERIFIED.
