Xen support hasn't been dropped, we are probably just failing to detect
that xen is available.

First, can you try 'virsh --connect xen:///' and see if it succeeds? If
that works, you can manually pass the connection string to virt-install
in the interim (virt-install --connect xen:/// ...)

Can you also check if the following 3 locations exist:


That is what we check in virtinst to guess that xen is present, and we
should use its connection by default. If one of those is missing, any
recommendations on how to detect xen presence would be appreciated.
