Config similar to

name="blabla"
memory=1024
vcpus=4
...
builder="hvm"
device_model="/usr/lib/xen/bin/qemu-dm"
kernel="/usr/lib/xen/boot/hvmloader"
boot="d"
disk=[ 'file:/var/lib/xen/images/sles11sp1 gmc-hvm/disk0,hda,w', 
'file:/path/to/centos6.iso,hdc:cdrom,r', ]
...

/etc/xen/examples/ contains quite a few examples for both pv and hvm. 
But vm-install should help with the installation.  Just ensure to check
"Full virtualization" for Virtualization Method.

Jim
