Subject: [pve-devel] [PATCH qemu-server 10/11] live-restore: register qmeventd handle
Date: Mon, 11 Jan 2021 12:14:08 +0100	[thread overview]
Message-ID: <20210111111409.32385-11-s.reiter@proxmox.com> (raw)
In-Reply-To: <20210111111409.32385-1-s.reiter@proxmox.com>

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).
