Hi Jon,
Nice one. I can confirm it works at my side too, successfulyl
plugged/unpluged vbd to dom0,
including the ones on my ocfs2 storage.

Unplugging also works, but leave this entry in the dmesg:
[ 1072.380954] WARNING: g.e. still in use!
[ 1072.381029] WARNING: leaking g.e. and page still in use!
I don't know if this is relevant to something bad. Anyone knows what it
means ? Should it be ignored ?
Thanks a lot for your work.
I'm now going to test the network things. Talking about this, does it
makes sense to use standard bridged
networking when openvswitch is available ? Looks to me like in XCP and
XenCenter beta (project boston)
it has been replaced by openvswitch.
The openvswitch version provided by the debian sid repository contains a
kernel module that does not
recompile compile against a 3.0.0 kernel, it has checks that looks for a
"2.6" in kernel version.
So I have built the latest openvswitch version from the git repo as
debian packages and vswitch is up
and running on my sandbox.
Any lead on how to use openvswitch layer with xapi on debian ?
The file
/usr/src/openvswitch.last/xenserver/opt_xensource_libexec_InterfaceReconfigureVswitch.py
exists, but how to tell xapi to use this instead of bridge ?
I'm maybe going a bit too fast about this, but I'm ready to test it :)
Cheers,
Sébastien

I've uploaded a new deb, which Works For Me. Give it a spin and see how it goes!
