This is a hardware limitation and there's nothing that can be done. The only way to run Xen on that box is to use Linux in PV mode, which FreeBSD doesn't support. You can check the CPU features at: https://ark.intel.com/content/www/us/en/ark/products/63918/intel-celeron-processor-867-2m-cache-1-30-ghz.html Search for VT-d. If you want to run FreeBSD/Xen you will need a newer CPU, sadly there's no way around that. > > > > Do you have a serial console attached to the box so that we could > > > > see the log of Xen and FreeBSD booting? > > > > > > how to? every time I boot into xen I have to zpool import -f and mount it > > > from rescue CD.

See: https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/serialconsole-setup.html That way you can get the output of FreeBSD or Xen booting in text mode, so that you can for example paste it on an email when things go wrong.
