[pve-devel] [PATCH v5 14/15] ui: window/Migrate: allow mapped devices

[Dominik Csapak <d.csapak@proxmox.com>]

if the migration is an offline migration and when the mapping on
the target node exists, otherwise not

this does not change the behaviour for 'raw' devices in the config
those can still be forced to be migrated, like before
