Question:
Is there any option for a more verbose output or the source of the qemu-ut-pdk snap?

Searching for the issue on the internet surfaces this: https://forum.manjaro.org/t/snaps-stopped-working-after-2020-12-30-update/45518/13

It's possible you need to upgrade your kernel to something newer, since this is a mismatch between snapd's AppArmor profile and the AppArmor support in the kernel.

For some reason I thought it was a PDK specific problem. Updating the kernel helped, but I still couldn't get the PDK to run on OpenSUSE, so I switched to Ubuntu. Perhaps the errors that have occurred are a topic for new issues, but this one can be considered closed, or renamed to something like "launching PDK on OpenSUSE"
