Something worth of note: To generate a valid SAS address I need an IEEE number. I seem to remember Qumranet donated their PCI id for KVM use. I don't actually know if that donation extends to the IEEE number, too. If not then obviously I would need to use another one here. Who would be best in a position to answer this? Paolo? Someone at RH should know ... Cheers, Hannes -- Dr. Hannes Reinecke zSeries & Storage h...@suse.de +49 911 74053 688 SUSE LINUX Products GmbH, Maxfeldstr. 5, 90409 Nürnberg GF: J. Hawn, J. Guild, F.
