there were some changes in how networking is done going from 5.0 to 5.1.
You may need to revisit the documentation for CentOS 5.1

Hello,
I have a big problem:
Dom0 is centos5.1, domU are centos5.1. My setup is really simple, the
only thing is that I give 3 nics to the domU so I use a modified
network script (which has worked since january... since fedora 6):
"
#!/bin/sh
dir=$(dirname "$0")
"$dir/network-bridge" "$@" vifnum=0
"$dir/network-bridge" "$@" vifnum=1
"$dir/network-bridge" "$@" vifnum=2
"
So I have updated my xen dom0 from 3.0.3-rc5-8.1.15.el5 to
3.1.0-53.1.4.el5 (and kernel-xen 2.6.18-8.1.15.el5xen to
2.6.18-53.1.4.el5xen) and now my domU cant access the network. The
interfaces are good in the domU, all seems to be ok but there are no
connectivity at all (no arp entries). This message shows up on the
dom0 each time I launch a domU:
blkback: ring-ref 9, event-channel 7, protocol 1 (x86_64-abi)
Do someone know what is happening ? this is very embarrassing after a
simple upgrade... Hopefully I have another identical server (Centos
5.0 with 5.1 domUs) which is still in 3.0 but I cant stay not updated.
Thanks for any help.
