[Rdo-list] Juno kvm/qemu fail to start after hypervisor reboot

[Ramakrishna Nishtala (rnishtal)]

Hi
Has anyone encountered this problem?
The VM comes up fine for the first time. But when hypervisor is rebooted, it never comes back online.

Issuing a virsh start goes through series of checks but shuts off again.
Only thing found from instance libvirtd/qemu log file is

qemu: terminating on signal 15 from pid 4067

The process 4067 is libvirtd itself.

Tried with both qemu/kvm, local or volume, rhel guest and server images, the problem remains.
Any clues appreciated.

Regards,

Rama
