Hi, i have some problems creating a second bridge for my second nic. I''m using the following script (two-bridges): ................................................................................................................................... #!/bin/bash XENDIR="/etc/xen/scripts" $XENDIR/network-bridge "$@" netdev=eth0 bridge=xenbr0 vifnum=0 $XENDIR/network-bridge "$@" netdev=eth1 bridge=xenbr1 vifnum=1 ................................................................................................................................... And patched xend-config.sxp like this: (network-script two-bridges). xend creates both bridges, but when call »brctl show« both bridges are using the same bridge id (the nics seem to be assigned correctly)! I can ping the ips assigned in dom0 but nothing else. The domU has no working network. When i check my routing table (»ip route show«) the listing is quite slow but looks okay? Does anybody know, what''s going wrong? My system is SuSE 10.2 with xen 3.3. Thanks!

I had this problem on opensuse 10.2 as well. I was following the HOWTO at http://en.opensuse.org/Xen3_yet_another_Virtual_Network_Concept I could ssh from dom0 into a domU, but once I was in a domU i could not ssh into dom0 or any other machine, nor could I get access to websites. I suppose this confirms that a networking problem exists in 10.2, but not what the problem is. After upgrading to 10.3 (yesterday) and installing a virtual machine my networking problems disappear. I can ssh from a domU to dom0 and can view web pages. If your hangup is networking you might consider trying opensuse 10.3.

Is it kernel, hypervisor, something else?

Re: [Xen-users] Problem using 2 nics and 2 bridges
Hello Razi, if i can''t solve the problem the next few days, i will upgrade the system. Good to know that this would be a workaround. Do you remember, if on suse 10.2 both bridges on your system got an equal bridge id too? Perhaps this will be a problem?! regards Harry Am Sonntag, 28.
