Xen appears to configure the same MAC address for both the frontend
and backend in XenStore. e.g.
[tal@dom0 ~]$ xenstore-ls /local/domain/3/backend/vif/19/0
frontend = "/local/domain/19/device/vif/0"
mac = "00:16:3e:5e:6c:00"
[...]
[tal@dom0 ~]$ xenstore-ls /local/domain/19/device/vif/0
mac = "00:16:3e:5e:6c:00"
This works if the client uses just a simple ethernet device, but fails
if it connects via a bridge. HVM domains have an associated stub domain
running qemu, which provides an emulated network device. The stub domain
uses a bridge to connect qemu's interface with eth0, and this didn't
work.
Force the use of the fixed version of mirage-net-xen, which no longer
uses XenStore to get the backend MAC, and provides a new function to get
the frontend one.
