[qemuserver.pm] Subject: [pve-devel] [PATCH v2 qemu-server 10/11] live-restore: register qmeventd handle X-BeenThere: pve-devel@lists.proxmox.com X-Mailman-Version: 2.1.29 Precedence: list List-Id: Proxmox VE development discussion List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 03 Mar 2021 09:57:56 -0000 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).
