Re: [Xen-devel] Xen 3.3.1 latest / starting guests causes Oops in tapdis
It might be interesting to try xen-unstable which should now be switched
over to blktap2 by default. Quite apart from being interested as to how well
that works right now, I also imagine you can get quicker responses from the
developers of that. If it works, blktap2 would port over to 3.4 quite
easily. Probably 3.3 too.
