With Ubuntu 18.04
1. without --bypass-cache qemu errors out,
# virsh save virt-tests-vm1 /var/tmp/save.file
Domain virt-tests-vm1 saved to /var/tmp/save.file
# virsh restore /var/tmp/save.file
error: Failed to restore domain from /var/tmp/save.file
error: internal error: qemu unexpectedly closed the monitor:
2018-02-27T12:54:55.160391Z qemu-system-ppc64: Not a migration stream
2018-02-27T12:54:55.160488Z qemu-system-ppc64: load of migration failed:
Invalid argument
Does this error appropriate/expected ? Earlier Libvirt was handling the
error for apparmor permission denial, but in bionic Qemu errors, I still
feel the inconsistency and it would be better to document well to make
sure users/customers to understand how it works / how to use
2. with --bypass-cache it works with /var/tmp
# virsh save virt-tests-vm1 /var/tmp/save.file --bypass-cache
Domain virt-tests-vm1 saved to /var/tmp/save.file
# virsh restore /var/tmp/save.file --bypass-cache
Domain restored from /var/tmp/save.file
3. in /var/lib/libvirt/images it works fine without issues,
# virsh save virt-tests-vm1 /var/lib/libvirt/images/save.file
Domain virt-tests-vm1 saved to /var/lib/libvirt/images/save.file
# virsh restore /var/lib/libvirt/images/save.file
Domain restored from /var/lib/libvirt/images/save.file
