Currently there's no alternate reality available in which one can run Remus? blktap - not really there (and it would have other nice features) dr:bd - doesn't play with xl xm - not supposed to use that any more older distros - will not take remus patches i guess older howtos - broken since Remus is already part of Xen by now (And I don't think it will get better by pointing at a workaround else if one thing that should work isn't working. Instead, soon, it will no longer work at all)
