Paul: The actual array is attached to dom0, and it's dom0 that's crashing when the register process on dom0 starts talking to the raid controller. Inside the domUs, they only get the generic xen device (disk image on a logical vol, on a different array/controller) that's presented to them. numpty: As noted in the update, the cobag in question isn’t a known employee of any company.

Is the panic occurring in the dom0 or domU RHE instance? If the latter, the BUI needs to be told where the proxy is. The registration wizard will search for you, but I wonder if when the search is being done in the domU (which will be fruitless since it is a virtual machine with virtual drivers), the aacraid driver is choking on the virtual drivers. A possible work-around is to specify the ip address of the dom0 host in the registration wizard. The BUI and the proxy communicate via TCP/IP. As long as there is network connectivity between the domU and dom0 (which is required for CAM to work in your setup), specifying the ip address of the dom0 host in the registration wizard will prevent the discovery from happening in the domU and only occur in the dom0 (which is what you want).

There are good people and bad people in every community; don't kid yourself that just because GNOME isn't a business, that there aren't assholes in our midst.
