[pve-devel] [PATCH v2 qemu-server 10/11] live-restore: register qmeventd handle

[Stefan Reiter]

Similar to backups, prevent QEMU from being killed by qmeventd during
the live-restore, so a guest can shut itself down without aborting the
restore operation.

Note that the 'close' is only to be explicit, the handle will also be
closed in case an operation errors (i.e. when the 'eval' is left).
