[CentOS-virt] sorting virtual network interface names with xen

[lee]

Hi,

how would I make it so that a particular virtual network interface of
dom0 is attached to a particular bridge created for a particular VM?

When I start the VM with 'virsh start <domU>', I get interfaces vif1.0,
vif1.1 and vif1.2.  After shutting down domU with 'virsh shutdown
<domU>' and starting it again as before, the virtual network interfaces
are vif2.0, vif2.1 and vif2.2.

I want them to keep their names so that they would be vif1.[0-2] again.

In the end, I want to give them different names, like vif_domU.loc,
vif_domU.dmz and vif_domU.mta, which they are supposed to keep
consistently.

Is it possible to hardcode the interface names in the domain
description?  Currently, the default script /etc/xen/scripts/vif-bridge
is used to create them.

And once hardcoded, how do I make it so that the corresponding
interfaces in domU have appropriate names like eth_loc, eth_dmz and
eth_mta?

Generic interface names for all the bridges and interfaces would lead to
total confusion in this case because I`d never be able to tell which
bridge or interface in dom0 corresponds to what in any of the domUs.
