You nailed it! To export from dom0 (to real network -- not tested with domU hosts) you have to tell vblade to bind to xen-br0 (on xen2 -- not tested with xen3) not eth0. I never would have thought to do this as dom0 should be as close to "real" linux as possible. So in summary for aoe on xen: 1. Compile aoe in kernel (Device Drivers/Block devices/ATA over Ethernet) to be able to see aoe devices (remember you can't see vblade exports on the host exporting them). Module did not work for me, but your milage may vary ;) . 2. If you want to use vblade (http://aoetools.sf.net) to export a disk/lvm/loopback device, you have to use xen-br0 (for xen2 -- adjust for xen3) NOT eth0. Thanks for the help on the list. PS - I'm getting in the 3U SATA raid from coraid in a week or 2, and assuming I can get xen3 on my single proccessor Sun V20z (Opteron), I will post performance numbers from dom0 and domU. As the sata boxes do raid on board, it should be a great option for large and/or redundant shared drives for xen migration. -- Jeb Campbell jebc@c4solutions.net
