I have the same problem on a ProLiant ML350p Gen8 when trying to install (using virt-install with PCI passthrough --host-device=....etc) using the integrated Broadcom NetXtreme BCM5719.
I also have an Intel dual port I350 on the system and with it everything is works as expected (virt-install with PCI passthrough).
