[Ukfreebsd] Hosted FreeBSD Servers

At the moment - it doesn't offer me the ability to do the XEN equivalent of
vmotion - so basically the only way to move from machine to machine is to
shutdown the VM and start it up again.

I've read the information about PV kernels - as you say, don't really want
to go there - am wanting to be able to offer FreeBSD to more than just
techie clients -- i.e to be able to offer it as an alternative for web
hosting etc.

Also noted a few comments on various mailing lists about getting people
interested in integrating - it would be great and we are willing to wait it
out - and see if the development path comes good...

Thanks ever so much for your help - we will talk amongst ourselves and with
the sales team and see if we can deliver the service as is.
