-Subject: Only check for cluster fs if we're using a filesystem
-
-otherwise migration fails for e.g. network filesystems like sheepdog
-with:
-
-   error: Invalid relative path 'virt-name': Invalid argument
-
-while we should fail with:
-
-    Migration may lead to data corruption if disks use cache != none
