I’m seeing duplicated reboot events when using the python event api. Use is simplified down to the simple test case attached. Running with that results in:
$ sudo ./libvirt_events_single.py Reboot: Domain i-06945b37(21) 1494958504.72 Reboot: Domain i-06945b37(21) 1494958504.74
Can you try with newer libvirt?
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?
Does this happen with 'virsh event --loop --event lifecycle’?
“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
Is there anything fishy going on when looking at the console (VN/spice) during that reboot?
Don’t see anything unusual. I can send you the full console output if you want, but I don’t see anything strange. Thanks Martins
This is reproducible 100% of the time by doing /sbin/reboot from within a VM started with qemu-kvm. Any ideas on whats going on?
Let me know if any other information would be useful.
Thanks
Martins
