Oh, actually upon looking again I spotted something:

nvme nvme0: pci function 10000:e1:00.0

Note the wider-than-16-bits segment number. Which, afaict, is an effect of
using the Volume Management Device:

vmd 0000:00:0e.0: PCI host bridge to bus 10000:e0

You may want to go through firmware setup options to see whether there's a
way to disable it / its use. Neither Xen nor the Dom0 Linux kernel (i.e.
when run under Xen) have been enabled so far to make this work (and, from
inspection quite a while back, the kernel implementation, during its design,
not having considered the possibility of running on a type-1 hypervisor will
likely make adding support, well, interesting).
