and:
- If 4GB or more are allocated to the domain, you get this:
PCI: Warning: Cannot find a gap in the 32bit address range
PCI: Unassigned devices with 32bit resource registers may break!
and the device shows up as disabled and is not usuable.
- No support yet for 'reassign_device' which page aligns the BARs
on PCI devices.
- Haven't tested FLR or PCI AER.
- Saw this once:
WARNING: at drivers/pci/msi.c:602 pci_enable_msi_block+0xcd/0x339()
.. snip ..
Call Trace:

But besides that it works :-)
