[libvirt] Not able to run "virsh qemu-agent-command" when socat is working

[Puneet Bakshi]

Sorry, that was a typo. But, it is still not working. (For some reason, I
had to move to Windows2012 with name vm_win_05).

[root at sdsr720-14 virtio-win]# echo "{'execute':'guest-ping'}" | socat
stdio,ignoreeof /var/lib/libvirt/qemu/g05.agent
{"return": {}}

[root at sdsr720-14 virtio-win]# virsh qemu-agent-command vm_win_05 '{
"execute":"guest-ping"}'

[root at sdsr720-14 virtio-win]#

Regards,
~Puneet
