Why not just give the 2 LV's to the dom0, and raid it on the dom0

With that setup, are you able to do live migration ?

no he cannot

he can do live migration if he make the raid1 inside domus

That's what I thought...



Why not?

Live migration only relies on shared storage on the dom0, not on the domU

Then, how do you achieve shared raid1 ? How may the first dom0 be aware of the mirroring the other dom0(s) is(are) doing ?
I must be missing something here.
