[PATCH V1 0/3] allow cpr-reboot for vfio

Posted by Steve Sistare 1 year, 11 months ago

Allow cpr-reboot for vfio if the guest is in the suspended runstate.  The
guest drivers' suspend methods flush outstanding requests and re-initialize
the devices, and thus there is no device state to save and restore.  The
user is responsible for suspending the guest before initiating cpr, such as
by issuing guest-suspend-ram to the qemu guest agent.

This series depends on the series
