Not 100% it's a bug or something i did wrong, but,

with xl create i start a PV with 3 pci passthroughs

after wards, xl pci-list shows all 3 nicely

looking at the domU boot logs, pcifront is only creating one pci device
and lspci in the guest shows only 1 pci entry

in at least 4.14.1 it still works.

This reminds me of my report at

Meanwhile the proposed pciback change has gone in upstream:

I wasn't, however, aware that this may have been an issue going
from 4.14.1 to 4.15.0, i.e. something that was presumably (as
George also has just said) a regression in the tools. Or else I
probably wouldn't have suggested taking care of this in Linux.
Nevertheless you may want to give that change a try.

Well, both tests have only different tools en hypervisor, no kernel
was changed between both tests, neither in dom0 or domU , so, it might
not be pciback?

forgot to mention, dom0 is 5.7.19 and domU is 5.10.27 for all tests
