I’m not sure. I will have to see if I can build it, unless there is a repo somewhere with centos7 rpms. I assume by this you mean that you don’t see this with current libvirt?

“lifecycle” shows no output, but with “reboot” or “all”:
$ sudo virsh event --loop --all
event 'reboot' for domain i-06945b37
event 'reboot' for domain i-06945b37

Don’t see anything unusual. I can send you the full console output if you want, but I don’t see anything strange.
