network dead after xend started

network dead after xend started

[Michael Stoehrel]

Installed xen-2.0.4 from sources.
boot 2.6.10-xen0 
interface has fixed ip
ping to other systems are good
ping from other systems are good
starting xend /etc/init.d/xend start
all networking is dead.
And of course after starting a vm the network is dead, too...

If I install the binary 2.0.4: No network at all:

what did I missed?

Michael

you probably got hammered by the bridge. 

do an ifconfig -a before and after xend and you'll see what I mean ...

Did you have an existing Xen installation and scripts, etc?
Try moving the old scripts out of the way - and make sure
your new scripts are getting deployed - it bit me too.

I've had this problem too, fixed it by starting xen-br0 manually at boot 
with commands:

  ifconfig eth0 0.0.0.0 promisc up
  brctl addbr xen-br0
  brctl setfd xen-br0 0
  brctl sethello xen-br0 0
  brctl stp xen-br0 off
  brctl addif xen-br0 eth0
  ifconfig xen-br0 xxx.xxx.xxx.xxx broadcast xxx.xxx.xxx.xxx netmask 
xxx.xxx.xxx.xxx up
  route add default gw xxx.xxx.xxx.xxx

works for me

Regards,
Anton Titov

I'm trying to track down this problem - I'd like to ensure
stuff starts automatically without manual fiddling  - so if
you have any more info on what broke for you, let me know,
I'd appreciate it!

thanks,
Nivedita
