The current driver is a hack, which creates the shared page when invoked (in dom0) with "create" as a module param. However, you can attach as many domUs as you want to that same LAN. > Any idea why there's UDP degradation? No 8(. I'm going to write a block driver and see what that's like. I was surprised at how aggressively Xen is switching between domains when an event channel was activated: so much so that we rarely got 32 packets off before the switch. Less aggressive scheduling will definitely help us, and possibly help the existing drivers. > This stuff looks awesome :-) Thanks, just fiddling. It'll be interesting to see what changes the PPC guys will need for this. Cheers!
