Xen users - Jun 2013 - Errors creating Domu with xl/xm on Xen 4.1.5 with Fedora Dom0

I want to get couple of DomUs running with Xen. I installed Xen 4.1.5 from
source on a Fedora 17 Dom0.

I did some reading on configuring DomUs using xl/xm and cfg files.
http://www.fclose.com/b/linux/2544/setting-up-lvm-backed-xen-domu/
http://www.fclose.com/w/Setting_Up_Xen_DomU_on_Fedora:_Unmodified_Fedora_on_Top_of_Xenified_Fedora_Xen_Dom0%23Install_Fedora_12_Linux_via_Internet

So basically I create the cfg file, and do "xm/xl create xmf16install
-c"
This is one of my cfg files.

name="xmf16install"
memory=2048
vcpus=1
disk=[''phy:/dev/xenvg/xmf16lvm,xvda,w'']
vif = [ ''bridge=br0'' ]
kernel = "/home/fedora16pxe/vmlinuz"
ramdisk = "/home/fedora16pxe/initrd.img"
onreboot = ''restart''
oncrash = ''restart''

The CentOS/Fedora installers are being launched, but I think I am running
into a problem when the installers ask for HTTP location from where to
pickup the images for install. I got different kinds of errors each time (I
tried multiple installations (F15,16, F17, CentOS5).

Some of the errors I got from the anaconda installers were
(F12, CentOS5)
'''' loader received SIGSEGV!  Backtrace:

F(15)

I am guessing there is a problem when it tries to connect to the internet
to download packages.
I have also attached my domU cfg file for reference in the email.

Could someone point out where am I going wrong ?

Is there something wrong with my cfg files. Or is something else the issue
here ?
