Two of the DomUs on each machine have dedicated network ports. At

do this documented anywhere and can I make the change without
having to rebuild the DomU?
Not quite sure what your asking? Can you give a little more detail
on what you want to do?
As you know the 4150 has 4 e1000g ports. Our configuration is that
Dom0 uses e1000g0, DomU[0] uses e1000g1, DomU[1] uses e1000g2 and
DomU[2]&[3] use e1000g3 At present all the DomUs have the
networking defined as per the snippet of xml below which, from my
understanding, means network traffic goes through the Dom0 via a
vnic before leaving the box on the specified port. I thought I had
seen a comment in a post some months ago that in the situation we
are in for DomU[0] and DomU[1] the "scripts/vif-vnic" could be
replaced by "scripts/vif-dedicated" (or something similar) and with
some other reconfiguration network traffic could go directly from
DomU[0] to e1000g1, bypassing the vnic through Dom0, similarly for
Domu[1] and e1000g2. Have I mis-understood the situation?
Ah, yes... There are two hotplug scripts, vif-vnic for using a vnic
and /usr/lib/xen/scripts/vif-dedicated for dedicating a NIC to a
guest.
<interface type='ethernet'>
<mac address='XXX'/>
<script path='/usr/lib/xen/scripts/vif-vnic'/>
<target dev='vif-1.0'/>
</interface>
I haven't done this myself, but I believe you just need to replace the
script path.
...and ensure that the 'bridge' parameter specifies the link that you
plan to dedicate to the guest.
