Description of problem: Service qemu-guest-agent fails to start.

Version-Release number of component in guest: qemu-guest-agent.x86_64                 2:2.11.1-2.fc28 @anaconda

How reproducible: Enable component (successful command).

Actual results: Subsequent commands –systemctl status/start qemu-guest-agent– produce error messages:

$ systemctl status qemu-guest-agent

Expected results: no reason for errors messages

Are you trying to run it inside a properly configured VM? The guest agent service won't start unless there's a org.qemu.guest_agent.0 virtio channel attached
Comment 2 ricky.tigg 2018-06-12 19:51:02 UTC 
I Just changed actual set on a shutdown domain following manual procedure on section 11.1.1.1 at  
https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/pdf/virtualization_deployment_and_administration_guide/Red_Hat_Enterprise_Linux-7-Virtualization_Deployment_and_Administration_Guide-en-US.pdf.

virsh # edit <domain>
...
    '<channel type='spicevmc'>
      <target type='virtio' name='com.redhat.spice.0'/>
      <address type='virtio-serial' controller='0' bus='0' port='1'/>
    </channel>'
to
    '<channel type='unix'>
      <target type='virtio' name='org.qemu.guest_agent.0'/>
      <address type='virtio-serial' controller='0' bus='0' port='1'/>
    </channel>'

At last this service allowed for being started.
