That didn’t work quite as planned.
Can I even disable my PCI device for the initial setup of VMs right after installation in the default flow (not with the initial-setup-graphic script)? There is no TTY: Can't enter into TTY from the initial setup
I booted the 4.2-rc5 system without the setup and tried digging into the issue when running initial-setup-graphic (as a reminder: ValueError: ‘Fedora 38 Xfce’ is not in list.). There was this error around NVDIMM (failed to load module nvdimm: libbd_nvdimm.so.2: cannot open shared object file: No such file or directory), which others had too. I found that libblockdev-nvdimm is not installed, should it possibly be? Unfortunately I can’t install it without the VMs as per dom0 design.
In all these attempts, I found that the initial setup breaks the initial setup. What I mean with this is that if I quit the initial setup (literally with the Quit button, see below) and boot the system, the system is pretty broken, can’t use the Q icon and a few features because I think the system expects the host to have dom0 as its name, but it is localhost. It complains about a missing key localhost in a python script for the menu. However, disabling the PCI device and then running the initial setup script works. So the initial setup breaks my chance of running it later when I select that I would like to setup nothing at this point which I absolutely need with my unsupported PCI device though. A quit before entering the submenu with the settings doesn’t do this.
Would this approach result in a usable system? I hope this helps debugging the issue with the initial setup at least.
