If XCPs linux kernel exports his config to /proc/config.gz (check if that file 
is there) and if you just want the kernel config you can just get out the 
configuration of the running linux kernel you can use:
        zcat /proc/config.gz > /usr/src/your_kernel_sources/.config

if you want to use the default kernel configuration.

Make shure you are using a xenified linux kernel (i.e. SuSe ones) - otherwise 
xens functionality would not be used / there.

i won't makes sense to run such a kernel as DomU as it is designed for Dom0.

Do you mean XCP ISO?

It's intended to run on bare metal, not as a VM.

It can work as HVM domU, but performance-wise it'd suck. Still useful
for testing purposes though.

any 64bit HVM OS template should work, as long as it has pae and acpi on.

If you're thinking about using custom kernels, you might be better off
using a linux distro that comes with xen (opensuse, centos, ...)
