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

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
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
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.
Knowledge is volatile and fluid. Software is power.
