Hi,
I'm afraid I actually don't know that much about SELinux but I read
that it relies on using extended attributes in the file system to
accomplish its labeling.
Do you still experience this issue when you enable extended attribute
support[1] in virtiofsd? The example in the optional parameters snippet
enables extended attributes with the xattr='on' element.
