Hey, I have a problem with xen networking. I'm using centos 5.5 64bit, and have installed xen 3.4 from gitco (unofficial) repository, along with libvirt and xen-tools. I got it previously working on official xen (3.2 iirc) without much of a hassle - I believe network just worked in default settings, with bridged settings (given that I provide= mac address for guest adapter that hetzner - my hoster - set up for me for my additional ip, my guest windows os will just found dhcp server and all will work automagically).
However, now I can't get it to work. If I leave default network-bridge xen settings enabled, my dom0 instantly gets down after reboot or xend restart. I don't really know what happens, since the only way to get my server back is to reboot it...
I've also tried routed setup, but I did not work after a few hours of struggling to set it up properly, so I eventually gave up, as it seems to be more challenging setup... so I'd rather try to get bridged attempt to work.
The settings in xend.sxp I want to use are:
(network-script network-bridge) (vif-script vif-bridge)
Here is my ifconfig if I comment out everything network-related in xend.sxp along with the ifconfig after starting the network-bridge (i.e. there is already no connectivity when it happens - I've dumped it to the file): http://pastebin.com/nPT8nVBc - is the Bcast of 0.0.0.0 normal for the already-virtual eth0?
I've tried running the network script by hand to see what will happen:
cd /etc/xen ./network-bridge start; ./network-bridge stop
but no luck, it still goes down somewhere in the process and doesn't go back - restarting is the only way to get my server back.
bash -xv ./network-bridge start 2>&1 | tee out.txt
gave me this output: http://pastebin.com/E6JPBb90 . Interestingly, the last line in ssh wasn't always the same: it would sometimes show up to the 305th line of the paste:
the other it would stop at 530th line:
+ ip link show peth0
Still, I don't know wha could I make out of it or what else should I try?
Sorry for the lengthy description. I would appreciate all kind of suggestions.
