To be consistent w/ the rest of the document you should put the following
paragraph into a “Note”:

“After installing the para-virtualized drivers on a guest operating system you
should only use the xm command or virsh to start the guests. If xm is not used
the network interfaces (for example, eth1 and so on) will not be connected
correctly during boot. This problem is known and the Bugzilla number is 300531
and a bug fix is in progress. The bug connects the network interface to qemu-dm
and subsequently limits the performance dramatically. “
