Requires two CPUs but doesn't mention that

It seems to check the amount of RAM and disk needed, but not the number of CPUs. You get this error if you only have one:

```

Start by reproducing the Qwen-VL server failure on a one-CPU system and inspect the resource checks and snap configuration in the inference-snaps repository. Done means the CPU requirement is checked or clearly reported alongside the existing RAM and disk requirements, with a test or documented reproduction covering the one-CPU case.
