Subject: [PATCH] xen: do not disable netfront in dom0
Date: Sun, 20 May 2012 13:45:10 +0200	[thread overview]
Message-ID: <20120522130558.D828E6C7@duch.mimuw.edu.pl> (raw)

Netfront driver can be also useful in dom0, eg when all NICs are assigned to
some domU (aka driver domain). Then using netback in domU and netfront in dom0
is the only way to get network access in dom0.
