Hi zhwang, can you reproduce it with restart libvirt-guests but not reboot host ?
hi dyuan, It works well with restart libvirt-guests, I wrote it in my description in step 7.
Hi, could you please verify it with the latest libvirt? I've tried to reproduce it, but the guest started correctly after rebooting the host. If it fails again, please include output of those commands: journalctl -n 100 -u libvirt-guests journalctl -n 100 -u libvirtd
Hi, I didn't reproduce the issue with the latest libvirt either, however, while i downgrade the libvirt to the libvirt-1.1.1-2.el7.x86_64, i can hit a similiar issue with the comment0 which the guest was in shut off status while the host was rebooted completely with the comment0's steps, but i can't see the guest's save img in /var/lib/libvirt/qemu/save. Maybe this issue has been fixed by the later libvirt packet.
