[Xen-users] TWO NIC WITH TWO BRIDGE NOT WORKS XEN 3.0.3 -- WHAT AM I WRONG ?
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:
-----------------------------------------------------------------------
#!/bin/bash
dir=$(dirname "$0")
"$dir/network-bridge" "$@" vifnum=0 netdev=eth0
bridge=xenbr0lan
"$dir/network-bridge" "$@" vifnum=1 netdev=eth1
bridge=xenbr1wan
"$dir/network-bridge" "$@" vifnum=2 netdev=dummy0
bridge=xenbr2dmz
# EOF
-----------------------------------------------------------------------
I want only the 192.168.0.0 net for dom0 and 10.0.0.0 for two domUs for now
(later I m´ll make new domu in 192.168.0.0).
My problem is that que te domU only has ping if I set the real MAC in the
dum´s cfg script.
domu1 works if add the real MAC in cfg file like this:
--------------------------------------------------------------------
# Networking
#
vif = [
''ip=10.0.0.55,mac=00:13:72:57:7B:AF,bridge=xenbr1wan'' ]
--------------------------------------------------------------------
domu2 works if add the real MAC in cfg file like this:
--------------------------------------------------------------------
# Networking
#
vif = [
''ip=10.0.0.15,mac=00:13:72:57:7B:AF,bridge=xenbr1wan'' ]
--------------------------------------------------------------------
domU 1 and domU 2 not works if I add a no real MAC o MAC is not present in
cfg domU´s file.
For example. If I make cfg with MAC random, empty o FE:FF:FF:FF:FF:FF,
appear the error:
Configuring network interfaces...SIOCSIFADDR: No such device
eth1: ERROR while getting interface flags: No such device
SIOCSIFNETMASK: No such device
eth1: ERROR while getting interface flags: No such device
Failed to bring up eth1.
Moreover, when I add the real MAC in domUs they work (can ping to any IP),
but if I have a ssh session with domU1 and open a new ssh session with
domU2, the network connection with domu1 crash.
So, I can not make two simultaneous ssh connections to domus using the same
real MAC
What is wrong?
Thanks a lot for help.
The dom0 ifconfig is like this:
