List:

I have a new installation of FreeBSD Current that won't boot the Xen kernel.
I loaded the most recent snapshot and then ran 'svnup' to bring my source
tree up to date on Saturday 10/17/2015.  I followed the instructions on the
FreeBSD Wiki page on setting up Dom0 support.  I made the changes to
sysconf.conf, /etc/ttys, /boot/loader.conf and generated a new
/boot/menu.rc.local.  When the computer was rebooted, it would not load the
Xen boot file and choked giving me the OK? prompt.

This is my dmesg output showing the CPU information:

Having a non-functioning entry in /boot/loader.conf is a tough one to recover
and requires booting to a live filesystem.  Loading one of the working
kernels still loads the same loader.conf.  This motherboard uses UEFI and was
installed with a UEFI kernel.  This computer was able to successfully load 
the
Citrix XenServer 6.5 and had all 'green' lights when I ran 'xl dmesg'.  I
used another hard drive for the Citrix load.  It seemed to be happy with all
of my CPU and hardware features.  I was able to make a DomU image from an
OpenBSD 5.8 snapshot.  I have been running FreeBSD since version 4.11 and
would prefer not to run the Citrix XenServer because of all of it's
'Linux-isms'.  Their filesystem uses Logical Volume Manager and I much prefer
ZFS for disk management.

Is there any other information that should be sent to this list?

Tom
