Re: [Xen-devel] Pygrub in Xen 3.5 unstable cannot read ISO image (CentOS 5.3, SNV_117).Cannot find kernel "/images/xen/vmlinuz"

I was able to perform install via HTTP source :-

# wget http://192.168.1.42/rhel/images/xen/vmlinuz
# wget http://192.168.1.42/rhel/images/xen/initrd.img

name="RHEL53PV"
memory=2048
disk = [''phy:/dev/sdb6,xvda,w'' ]
vif = [ ''bridge=eth0'', ]
vfb = [ ''type=vnc,vncunused=1'' ]
# bootloader = "/usr/local/bin/pygrub"
kernel = "/home/boris/rhel/vmlinuz"
ramdisk = "/home/boris/rhel/initrd.img"
vcpus=1
on_reboot = ''restart''
on_crash = ''restart''

# xm create rhel53.install
# vncviewer localhost:0
