[ovirt-devel] Fwd: [ovirt-users] How to use ovirt-guest-agent without VDSM?

Hi I have added channel device to vm already. And viewing vdsm/virt/guestagent.py now. Can give me some suggesting.

Hypervisor is Ubuntu 14.04 (OpenStack Icehouse) and the virtual machine is Ubuntu 14.04 cloudimage. In Hypervisor launch a instance and attach a chardev, like: # ps -ef | grep guest_agent libvirt+ 2649 1 1 Sep08 ? 00:15:36 /usr/bin/qemu-system-x86_64 ... -chardev socket,id=charchannel0,path=/var/lib/libvirt/qemu/org.qemu.guest_agent.0.instance-00000210.sock,server,nowait -device virtserialport,bus=virtio-serial0.0,nr=1,chardev=charchannel0,id=channel0,name=org.qemu.guest_agent.0 ... In virtual machine was installed ovirt-guest-agent 1.0.11-1.1 and service running OK. But i don't know how to get memory usage and other information in hypervisor(OpenStack compute node)? I have failed when i try to use linux command 'socat' and python socket. I need some sample or link. Thanks a lot!

I'm almost certain that ovirt-ga searches for a device with the name 'com.redhat.rhevm.vdsm' when starting up. Once you are connected, take a look at vdsm/virt/guestagent.py in the vdsm source code for hints about how to talk to the agent. -- Adam Litke
