peth.... :/
Personnally, I stopped rely on the networks scripts of Xen since uears.
As said in the Xen 4.1 release notes, thoose scripts are very fragiles
and I personnally find them evry complicated for what they really do:
configure the dom0 network. In the past I remember having some issue
related to arp being disabled on some underlying device or being nabled
whereas it should not... As you can see I don't clearly remember. :)
If you want to stick with the network-bridge scripts of xen ... may be
you can take a look at the ARP options of the devices. I would recommend
you let the OS take care of Dom0 network config (furthermore Xen 4.1
doesn't provides thoose scripts anymore i think).
I personnally use network-dummy as the network-script in xend-config.sxp
and configure Debian to setup a bridge at startup like this:
auto xenbr0
iface xenbr0 inet static
address 192.168.x.y
netmask 255.255.a.b
broadcast 192.168.x.255
gateway 192.168.x.z
bridge_ports eth0
bridge_fd 3
bridge_maxwait 5
This config allow HVM (here a vista host) to access network with the
following in its configfile:
vif = [ 'bridge=xenbr0' ]
Hope it helps.
