Green pipeline: https://gitlab.com/xen-project/people/marmarek/test-artifacts/-/pipelines/2498055947

Example Linux test:

Linux-next (20260504):
    https://gitlab.com/xen-project/people/marmarek/test-artifacts/-/pipelines/2496653697

A few genuine failures there:
- kbl-pci-pv-x86_64-gcc-debug:
   domU gets:

   (domU) [    0.449203] pcifront pci-0: xenbus: state reset occurred, reconnecting
   (domU) [    0.449426] pcifront pci-0: 22 freeing event channel 8

   and no PCI device ever appears
