VM Stuck on installing

Hi, I've tried using windows 11 as well as "Ubuntu 26.04 LTS". However, they build the disk and get stuck on installing. I'm not sure if this is user error or something else.

Reproduce the installation with Windows 11 and the Ubuntu ISO, then review the HCS callback, IDD probe, and HCS enumeration output after the VM reaches Running. Compare the installation logs around that point and determine why setup does not complete; done means the VM finishes installing rather than remaining stuck.
