Is there an existing issue for this?

What are you currently unable to do

When creating a virtiofs based disk device for a VM, POSIX ACLs are not passed to the VM.

What do you think would need to be added

It would be nice if a "posix_acl=true/false" (or similar) option could be added to the disk device type.

Virtiofsd supports passing POSIX ACLs and/or extended attributes (xattr), see man virtiofsd(1).

Alternative: add raw.virtiofsd disk option

Alternatively, add a raw.virtiofsd option to the disk device type.
