I think you meant PVH mode in the sentence above instead of PVM?
Sadly status is still the same, there's no support for PVH and PCI
passthrough on domUs yet.
Arm folks are working on using vPCI for domUs, which could easily be
picked up by x86 once ready. There's also the option to import xenpt
[0] from Paul Durrant and use it with PVH, but it will likely require
some work.
