Allow cpr-reboot for vfio if the guest is in the suspended runstate. The

by issuing guest-suspend-ram to the qemu guest agent.
Can you briefly explain what cpr-reboot is, or do you have a pointer to
some more details?
What is is good for, why would you use it, how does it work?
I *suspect* that you want to live-migrate a VM with vfio devices
attached, whereby you don't want to migrate device state.
