[Bug 2061701] [NEW] check_can_live_migrate_source fails with mkfs.vfat error: Label can be no longer than 11 characters

 

Public bug reported:

When testing NBD TLS live-migration the initial attempt failed. Looks
like a generated filesystem label is too long.

Subsequent attempts succeeded

$ nova-compute --version
