I use a custom kernel config containing:

include         MYNORMALCONFIGFILE
ident           SPECIALCONFIG

nooptions       XENHVM
nodevice        xenpci

The system running that is 10.1-STABLE #0 r283511 from May 24 2015.  It
previously ran an earlier build, probably from March or Jan.  re0 is
available with this config.
