[Fedora-xen] Re: How is network bridging for Xen handled in F7?

you have any existing guest config files which refer to 'xenbr0' they will
automatically join the eth0 bridge device instead. So existing guests are
supposed to 'just work' even though the Dom0 network config changed a little.
Dan,
I just ran into an issue with this.
I have re-built F8 xen-3.1.2 from SRPM on CentOS 5.1 x86_64 and done a
clean kickstart install of CentOS 5.1 x86_64 which pulls in the
xen-3.1.2 RPMs from a repo (i.e. xen-3.0.3 is never installed).
I have some guests created using xen-??? on FC6 which I have migrated to
a new machine and which use xenbr0.
When I try to start the domains using "xm create -c guestname" I got a
message about not finding xenbr0.
So, I changed xenvr0 to virbr0 and the guests start OK and can talk to
each other but can not talk to anything on the rest of the network.
I have figured that this is related to the issue discussed in this thread.
How come xenbr0 was not recognised? Do I need to update some other
packages, or should I use virsh?
Or do I just configure eth0 as a bridge in Dom0 as described here [1]
Thanks,
R.
