Title: during shutdown libvirt-guests gets stopped after file system unmount Status in lvm2: New Status in libvirt package in Ubuntu: Incomplete Status in lvm2 package in Ubuntu: New Status in lvm2 package in Fedora: Confirmed Bug description: When using automatic suspend at reboot/shutdown, it makes sense to store the suspend data on a separate partition to ensure there is always enough available space. However this does not work, as the partition gets unmounted before or during libvirt suspend. Steps to reproduce: 1. Use Ubuntu 18.04.02 LTS 2. Install libvirt + qemu-kvm 3. Start a guest 4. Set libvirt-guests to suspend at shutdown/reboot by editing /etc/default/libvirt-guests 5. Create a fstab entry to mount a separate partition to mount point /var/lib/libvirt/qemu/save. Then run sudo mount /var/lib/libvirt/qemu/save to mount the partition. 6. Reboot Expected result: The guest suspend data would be written to the /var/lib/libvirt/qemu/save, resulting in the data being stored at the partition specified in fstab. At boot, this partition would be mounted as specified in fstab and libvirt-guest would be able to read the data and restore the guests. Actual result: The partition gets unmounted before libvirt-guests suspends the guests, resulting in the data being stored on the partition containing the root file system. During boot, the empty partition gets mounted over the non-empty /var/lib/libvirt/qemu/save directory, resulting in libvirt-guests being unable to read the saved data. As a side effect, the saved data is using up space on the root partition even if the directory appears empty.
