I'am using 11.1-STABLE (r321629) as Xen dom0, running under
Xen kernel 4.7.2_3.

I have sucessfully started appliances built on oldish RedHat kernels
(2.6.32-573.18.1.el6.x86_64) without any problems. 
For Fedora 25 (4.10.8-200.fc25.x86_64) I had to add

xen_platform_pci=0

to the config file to get it running.
This still seems to be needed.

My disk definition for fedora and the RedHats
looks like this:

'/dev/zvol/zroot/fedora0,raw,hda,w'

(xvda seems to work well in place of "hda" for RHEL and Fedora
as well)

Forgot to mention, I use tiger-vnc [0] on OS X as the client.

That makes it the default, you don't need to press any key.

If you paste your guest config file + the serial output I might be
able to give you some clues.
