Subject: [pve-devel] [PATCH v5 qemu-server 03/11] parse_config: optional strict mode
Date: Wed, 9 Feb 2022 14:07:39 +0100 [thread overview]
Message-ID: <20220209130750.902245-11-f.gruenbichler@proxmox.com> (raw)
In-Reply-To: <20220209130750.902245-1-f.gruenbichler@proxmox.com>
when passing a config from one cluster to another, we want to be strict
when parsing - it's better to fail the migration early and upgrade the
target node instead of failing the migration later (when significant
work for transferring disks and/or state has already been done) or not
at all, but silently lose config settings that the target doesn't
understand.
this also might be helpful in other cases - e.g. when restoring from a
backup.
