That wouldn't be any different than if they were on separate Dom0s. You're talking about having two systems accessing the same block device. Honestly, for data that I need shared between multiple Dom0s or DomUs, I use NFS, and it still works great.

But supppose I need two domUs (in the same dom0) needing the same iSCSI resource. Could they share it if I configure it in the dom0? -- Angel L.
