Bug Description

Description of problem:
Added support for Intel VMD, which exposes 32-bit PCI domain numbers. Tooling needs to allow this.

Version-Release number of selected component (if applicable):
ahead of 0.13.4 (currently is 0.13.4)

Steps to Reproduce:
1. Enable VMD in Intel platform BIOS
2. Boot Ubuntu 17.04 in graphics mode

Actual results:
System halts at segfault in xstart

Expected results:
Successful boot

Additional info:
VMD provides a storage domain that does not need to be known by xstart, so these can be filtered out. The upstream patch that fixes this is provided here:
