*Is the "Protocol 'jabber' not found on CM 'gabble'" tracebackreproducible?*
No, it is not reproducible. I get it only when I start sugar desktop for
the first time after setting sugar.

 *I don't know what you mean by "able to see the buddy icon".  In the*
*context of the thread, I'm confused.*
I meant to say that we are able to see the buddy icon of the other vm in
the neghbourhood view only if the two Vms are on the same network. So if we
are able to see the buddy icon, this means that the vm's are able to
interact, isn't it?

Thanks!
