Thanks for the info Stephan. I'm taking your response into consideration and will most likely NOT go forward with this based on your response, as well as Oracle's response to this same type of question. They seemed to believe that performance may be impacted.
1) However, before I completely ditch the idea, does anyone know if this is even possible? <-- that is, using linux software bridges via the `brctl` command. 2) When you were using "dedicated iSCSI NICS" were you just connecting to the sessions from the dom0 and then passing the raw device through to the domU's as a physical device? I guess that is another way of doing this, but then I have to manage which blk devices are used for physical access to the domU and which ones are actually being mounted on the dom0 (for Oracle VM, these are mounted under /OVS/) Thanks, Joe On Oct 6, 2009, at 11:41 AM, netz-haut - stephan seitz wrote: > > Hi there, > > I'ld recommend not to export LUNs directly to domU's.
