Thanks for your assistance.
I ended up noticing what was wrong - the BAR required for MSI-X wasn't
being assigned but moving the card back to the original slot (not as
good for airflow) solved the issue and now the bars are assigned again
for some reason and it works once more. I wish I had checke

Hi,
I notice a problem with a PCIe endpoint, which is behind a PLX switch, assigned
to a VM by VFIO.
The problem is switch report a UR error when the EP tries to DMA to a memory
zone inside VM's address space.
Assume that the DMA destination address is between in the VM's ram address
space, and
