RE: [Xen-devel] xen-unstable on OL6 (RHEL6 clone) problems

Hi Pasi!

Actually I meant to mention in the original email, yes
this WAS very helpful, thanks very much for writing that
or I wouldn't have gotten as far as I did.

However, I am trying to install xen-unstable rather than from
rpms so this is Xen 4.1 (rc) not Xen 4.0 and I think that's
where my problems are.

Yep, did that both on an OL6 machine without Xen installed and
an OL6 machine with Xen-4.1-rc3 installed (built from scratch).
The bridging looks to be working fine on the machine without Xen.
On the Xen machine, I am still seeing a long sequence of

/sys/class/net/virbr0/bridge: No such file or directory

and that directory shows up fine with "ls -l".  That message
also shows up many times with "brctl show", so I suspect something
in the Xen install/startup is changing something that is confusing
something.  Or it is possible I committed some pilot error elsewhere.

Thanks for the help!
Dan
