[Xen-users] Some Xen newbie questions

[FreeBSD Prospect <mailings.freebsd@xxxxxxxxx>]

Hi!

I'm a total Xen newbie, and I just started reading into all that stuff. Until 
now I am curious about the following:

Where exactly is the kernel of a DomU stored, which is used for booting the 
DomU?

I may be confused by this, but it was mentioned that the Xen Dom0 kernel 
contains all the necessary hardware drivers, the Xen DomU kernel only the 
necessary Xen driver modules to interface with Xen, and that a DomU kernel 
can be reused by different DomUs, so I assume all used kernels simply go 
to /boot, which lies in the Dom0 filesystem,or will it be copied over to each 
DomU filesystem?

If an OS has been ported over to Xen, like FreeBSD or NetBSD, does that just 
mean the kernel of that OS has been ported, or does it include something else 
as well?

My idea was, to install Gentoo Linux in Dom0, and use pfsense (which is a 
firewall distribution based on FreeBSD 6.1) in the first DomU. I could not 
find any info about pfsense running with Xen, so I thought, most likely it is 
not about porting a distribution, but just the OS in General or specifically 
just the kernel, which would mean, as the ported version of FreeBSD 6.1 
should run in DomU, the use of the pfsense firewall distribution should be 
possible as well. Or are there any problems to be expected, if running a *BSD 
in a DomU with Linux in Dom0?
