Re: [Qemu-discuss] [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).

address@hidden virtio-win]# echo "{'execute':'guest-ping'}" | socat stdio,ignoreeof /var/lib/libvirt/qemu/g05.agent
{"return": {}}

address@hidden virtio-win]# virsh qemu-agent-command vm_win_05 '{ "execute":"guest-ping"}'

address@hidden virtio-win]#

Regards,

Note your spelling...

and compare it to here.  There is no guest_ping command, only
guest-ping.  It's a bug in libvirt that guest-agent-command doesn't
output a useful error message when attempting to run a non-existing
command, but you'll never hit that bug if you pass valid commands to the
agent in the first place.
