AD Child direct integration failure

[justin-stephenson]

On Fedora 34 I am trying to setup sssd-test-suite with AD and AD child for direct integration, I am running:

$ ./sssd-test-suite provision enroll child ad

This works fine, then I run and get this error about renaming:

$ ./sssd-test-suite provision enroll ad-child
...
<snip>

==> ad-child: Machine booted and ready!
==> ad-child: Setting hostname...
==> ad-child: Removing domain...
==> ad-child: Deleting the machine folder
Renaming the Windows guest failed. Most often this is because you've
specified a FQDN instead of just a host name.

Ensure the new guest name is properly formatted. Standard names may
contain letters (a-z, A-Z), numbers (0-9), and hyphens (-), but no
spaces or periods (.). The name may not consist entirely of digits.

I see the same error if I try running ./sssd-test-suite provision enroll client ad ad-child
