Support for running 32 bit Paravirt Xen VM's on a 64bit host was added
to 5.1 as a technology preview by the upstream provider. This means
that this has not been fully tested and is not supported.
I've also have been testing this and I had the same issues. Most of
the times I could not even get a install to finish.
So I guess the best thing to do is to create tickets for this in the
upstreams bugzilla and hope they have fixed the issues for 5.2

Hoping the problem magically goes away by ignoring it is the
"microsoft approach to programming" and should never be allowed.
