Hello, i will describe my approach
1) I have downloaded Centos5-64bit xen image from jailtime.org 2) I have created own swap image with 512MB file size 3) I have used same as dom0 kernel 2.6.18-53.1.19.el5xen 4) I have mounted my image file and copied /lib/modules/2.6.18-53.1.19.el5xen 5) I have created custom ramdisk for domU with mkinitrd --with=xennet --preload=xenblk /boot/initrd-2.6.18-53.1.19.el5xen.domU.img `uname -r` (uname -r = 2.6.18-53.1.19.el5xen) 6) Here comes my config file :
kernel = "/boot/vmlinuz-2.6.18-53.1.19.el5xen" ramdisk = "/boot/initrd-2.6.18-53.1.19.el5xen.domU.img"
memory = 512 name = "webdev"
vcpus = 2
vif = [ '' ]
disk = [ 'tap:aio:/home/xen/webdev/webdev_root.img,sda1,w', 'tap:aio:/home/xen/webdev/webdev_swap.img,sda2,w' ]
root = "/dev/sda1 ro"
7) when i will run domU machine using xm create webdev_config.xen -c , it will start booting but it will got freeze , exactly at step after starting crond
Using config file "./webdev_config.xen".
