I tried a litte bit further. Here is the output of guest-info:

virsh # qemu-agent-command windows7 '{"execute":"guest-info"}'
{"return":{"version":"0.12.1","supported_commands":
[{"enabled":true,"name":"guest-set-vcpus"},{"enabled":true,"name":"guest-get-
vcpus"},{"enabled":true,"name":"guest-network-get-interfaces"},
{"enabled":true,"name":"guest-suspend-hybrid"},{"enabled":true,"name":"guest-
suspend-ram"},{"enabled":true,"name":"guest-suspend-disk"},
{"enabled":true,"name":"guest-fstrim"},{"enabled":true,"name":"guest-fsfreeze-
thaw"},{"enabled":true,"name":"guest-fsfreeze-freeze"},
{"enabled":true,"name":"guest-fsfreeze-status"},{"enabled":true,"name":"guest-
file-flush"},{"enabled":true,"name":"guest-file-seek"},
{"enabled":true,"name":"guest-file-write"},{"enabled":true,"name":"guest-file-
read"},{"enabled":true,"name":"guest-file-close"},
{"enabled":true,"name":"guest-file-open"},{"enabled":true,"name":"guest-
shutdown"},{"enabled":true,"name":"guest-info"},{"enabled":true,"name":"guest-
set-time"},{"enabled":true,"name":"guest-get-time"},
{"enabled":true,"name":"guest-ping"},{"enabled":true,"name":"guest-sync"},
{"enabled":true,"name":"guest-sync-delimited"}]}}

So the agent command guest-get-vcpus is there. But:

virsh # qemu-agent-command windows7 '{"execute":"guest-get-vcpus"}'
error: internal error: unable to execute QEMU agent command 'guest-get-vcpus': 
unknown QEMU command error

Libvirt.log:

2014-11-05 21:47:51.498+0000: 1981: error : qemuAgentCheckError:1058 : 
internal error: unable to execute QEMU agent command 'guest-get-vcpus': 
unknown QEMU command error

Is this a qemu or a libvirt bug?
