https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Virtualization_Deployment_and_Administration_Guide/sect-Managing_guest_virtual_machines_with_virsh-Shutting_down_rebooting_and_force_shutdown_of_a_guest_virtual_machine.html
suggests that virsh reboot can take a comma separated list for the
--mode option and will try them each in turn.

It doesn't say the same for virsh shutdown but it might be reasonable to
assume that this is a docs issue not a functionality one.

If that were the case then I think the below would do the trick, but as
I say I don't have an immediately convenient way to test, nor a need
since there are no such tests right now.
