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

xen hotplug scripts not working
Hello Everyone,
I have set up a xen server with 10 physical network devices using the bridge mode of XEN. This is because I want to split and separate the network traffic for security reasons. Maybe the best way is to use pci back hide. But I want to understand what is going on here.
For all testings I have only activated eth[0-3].
My first tests were successful. I have created a VM using

Server with 2 Nics (continuation)
Hi *.*,
This is a continuation on the 2 NICs thread after some more testing.
Just to remember my goal.
---------------------------
I want to create a domU with 2 virtual NICS. One of them will contact
the outside world, the other one will contact a VPN. No reason in
concrete for choosing the bridging protocol, only because its the
default one. I installed the dom0 with the 2 NICs active, with

outgoing domu network dies after a while
I have a OpenSuse 10.3 with xen 3.1.0 running and it''s been running fine
for a few months.
This past weekend it suddenly started to act up and after some
troubleshooting I can now say that it seems like the guests(domU) loose
the outgoing network pipe, from the console I can see that the TX
counter is stuck at the same value but it''s no errors. It behaves as if

Problems with bridged networking
Hi,
I''m using Xen 3.0.3 on two servers with Debian Etch (amd64). These
servers have 10 nics (2 onboard and 8 in two 4-port cards) so that
every vm can have its own interface.
This worked so far with the Xen Version from Etch with a wrapper
script wich started 10 bridges at boot time. But now I''ve updated Xen
on one of these server to Xen 3.2.0 from backports.org and now the
