So Working on CEntOS 5 I am trying to sett up Xen with 2 bridges, one that
connects dom0 and most of the domU to the physical card and the out to the
network. Got that figured out no problem, now i want to have a second
bridge that runs a local network for all the doms that doesn''t connect to
the network.

Hello everyone.
I just installed Xen 3.0.3 in a debian etch box.
Linux server1.example.com 2.6.18-6-xen-686 #1
This server1 has two real nic (eth0 with real MAC 00:13:72:57:7B:AE and eth1
with real MAC00:13:72:57:7B:AF).
I made a network-bridge custom like this:

I have two nics. I just put the second one to DHCP and modified the

arpwatch has indicated flip flips. I can find no rhyme or reason to
predict them. I know I missed I must have missed a step somewhere.

xen 3.4.3 on CentOS 5.5 dom0: multiple nic issue -- eth1 won''t restart
Hi Folks:
I have a strange problem with multiple (2) NICs on a CentOS 5.5 dom0
setup running xen 3.4.3 and have been struggling to fix it for some
time. I could not find anything by googling or searching through this
list but that is probably because I couldn''t figure out the correct
search terms.
After I configure my bridges the command "system network restart" fails

I''ve setup Xen 3.0.2-2 (binary install) on Ubuntu 6.06, got my domUs up
and running, got them connected to the Internet but I can''t even ping to
any of these VMs.
Now I''m not linux/xen genious but could the problem be that xen-br0
doesn''t have an IPv4 address? (it''s got an IPv6 address)
Since I don''t use IPv6 on my network this seems a

Xen Dom0 network fails to start at boot
I have a server running Centos 5.2 as a Xen host. A problem that's
shown up recently is that at boot, the dom0 interface eth0 doesn't come
up properly, with the result that the host is only accessible via remote
console. If I execute 'service network restart', eth0 comes up
normally, with an IP address and the correct routing.

Hi,
we''re running 4 xen servers on our network with multiple network cards.

output looks as follows:

Hi all,
Has anyone seen this before? I''m running a CentOS 5.3 with xen 3.0 and the
server has been running fine for a long time. In fact, it was up for 186
days before I had to reboot after the "network died", and I couldn''t fix it.
The server has multiple domU''s on it, which all still works when the host

network-routing
Dear Xen-Users,
I use Xen 3.1.0_15042 on my OpenSuSE-10.3-computer. Without starting the
xen-kernel I can connect my second computer via my native computer to
the internet. After starting the xen-kernel the xen-bridge came
automatically up.
How can I configure the xen-bridge or the xen-devices?
I get routing problems:
