Subject: vdisk_list: skip scanning storages which cannot have images/rootdisks
X-Git-Url: https://git.proxmox.com/?p=pve-storage.git;a=commitdiff_plain;h=c43655d2ed63f1ca690807c7d6c3cdff8cce30b8

vdisk_list: skip scanning storages which cannot have images/rootdisks

Do not try to scan (and thus activate) storages which aren't
configured to support (or cannot support) "vdisks" anyway.

Avoids seemingly strange failures of VM migrations due to a backup storage
not being currently online - even if that storage isn't referenced in
the VM config anywhere..
