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

Hi, I am running qemu guest agent in Windows 2k8. I am able to execute "qemu-agent-commands" using socat but not through "virsh qemu-agent-command". *Guest VM xml* <controller type='virtio-serial' index='0'> <alias name='virtio-serial0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0'/> </controller> <channel type='unix'> <source mode='bind' path='/var/lib/libvirt/qemu/g06.agent'/> <target type='virtio' name='org.qemu.guest_agent.1'/> <alias name='channel0'/> <address type='virtio-serial' controller='0' bus='0' port='1'/> </channel> *Guest win2k8 is running following command* C:\qemu-ga> qemu-ga.exe -t c:\qemu-ga -p \\.Global\org.qemu.guest_agent.1 *Host CentOS system* socat returns response appropriately. [root@sdsr720-14 ~]# echo "{'execute':'guest-ping'}" | socat stdio,ignoreeof /var/lib/libvirt/qemu/g06.agent {"return": {}} *"virsh qemu-agent-command" returns blank.* [root@sdsr720-14 ~]# virsh qemu-agent-command vm_win_06 '{ "execute": "guest_ping"}' [root@sdsr720-14 ~]# Why "virsh qemu-agent-command" is not working? Am I doing something wrong here? Regards, ~Puneet
