Issues with newer style network interface renaming (em1, em2)

[antonym]

With the newer style network interface renaming which reflects the location of the device, (em1, em2, p1p2, etc) it causes issues when XAPI attempts to start. I was able to figure this out and get it working again by passing biosdevname=0 on the kernel command line.

Doing that reverts the default install of Ubuntu to utilize legacy interface naming (eth0, eth1, etc) and then allows xenserver-install-wizard to properly set up the devices. I also had to remove the old em1 devices with xe pif-forget before things worked.
