Re: [Xen-users] Using bonding-device bond0 for Xen

["Richard Mayer" <Richard.Mayer@xxxxxxxxxx>]

OK, Thank you very much for your help.

This option:

pre-up /usr/sbin/brctl setfd br-bond0 0

seems to have solved my problem.

I'm still getting this warning that Xen0 received a packet with its own
address as source:

satan:/opt/vmachines/vm1# ping satan-db
PING satan-db.dnbond0: received packet with  own address as source
address

but network connectivity of the XenU now seems to be ok!

I'll try if redundancy is also ok when I unplug one of the Ethernet
cables...

Thanks for your help!

This might be an normal IP network problem. Do you have a default
gateway 
within the domU?

pre-up /usr/sbin/brctl setfd br-bond0 0

might be a good idea to add as well.

You won't gain anything with it, it's much more complex.

It must be for new stuff for many - and difficult to understand as it's
light 
on documentation.
