Message-ID: <20250728143042.103045-3-f.ebner@proxmox.com> (raw)
In-Reply-To: <20250728143042.103045-1-f.ebner@proxmox.com>

The QMP reference docs describe the 'device' status as:

> During device serialisation (also known as switchover phase). Before
> 9.2, this is only used when (1) in precopy, and (2) when
> pre-switchover capability is enabled. After 10.0, this state will
> always be present for every migration procedure as the switchover
> phase.

Since Proxmox VE did not use the pre-switchover capability, it has not
been observed before QEMU 10.0. The state is still only reached during
block device inactivation, but it will be reached.
