Subject: [pve-devel] [PATCH qemu-server 5/6] template: add -snapshot to KVM command
Date: Fri, 4 Jun 2021 11:47:47 +0200 [thread overview]
Message-ID: <20210604094748.3383339-6-f.gruenbichler@proxmox.com> (raw)
In-Reply-To: <20210604094748.3383339-1-f.gruenbichler@proxmox.com>
this allows effectively setting ALL volumes as read-only, even if the
disk controller does not support it. without it, IDE and SATA disks
with (base) volumes which are marked read-only/immutable on the storage
level prevent the template VM from starting for backup purposes.
