Port Xen 3.3 to CentOS 5.2 has been done via http://www.gitco.de/repo/xen3.3.0 .
Install CentOS 5.2 PV DomU via virt-install in text mode utilizing NFS share with mounted loop DVD ISO image.
Create profile PV DomU as follows not using vfb at this time and setup “vnc” at DomU afterwords.
[root@ServerCentOS52 vm]# cat rhel52.pv-grub
name = “rhel-pvgrub”
memory = 2048
vcpus = 1
disk = [ ‘phy:/dev/sda10,xvda,w!’ ]
vif = [ “bridge=eth0” ]
kernel = “/usr/lib/xen/boot/pv-grub-x86_64.gz”
extra = “(hd0,0)/grub/menu.lst”
************************************
