This includes the following new types:

• c3-standard-192-metal
• c3-highcpu-192-metal
• c3-highmem-192-metal

It requires the idpf drivers to be installed (already in Fedora and RHEL9+) and the IDPF guest OS feature enabled on uploaded disk images.

The fix for this went into next stream release 41.20240916.1.0. Please try out the new release and report issues.
