Hi
Does anyone know how to use the images from http://www.jailtime.org/?
I've downloaded the CentOS 5.1
(http://www.jailtime.org/download:centos:v5.1) to my CentOS 5.1 x64
Xen 3.1 server, and unpacked it to my /home folder.
Then I took the included config file, centos.5-1.xen3.cfg and copied
it to /xen - and modified to my needs:
[root@gimbli home]# more /etc/xen/centos5-1
kernel = "/boot/vmlinuz-2.6.18-53.1.13.el5xen"
memory = 256
name = "centos5-1"
vif = [ '' ]
dhcp = "dhcp"
#disk = ['file:/home/vm/centos.5-1.img,sda1,w',
'file:/home/centos.swap,sda2,w']
#root = "/dev/xvda1 ro"
disk = [ "tap:aio:/home/vm/centos.5-1.img,xvda,w" ]
root = "/dev/xvda ro"
Probably you need a initrd image built using --with=xennet
--preload=xenblk and specify that as ramdisk= in the guest
configuration file and change the /etc/fstab references in your image
to xvda after loopback mounting that in dom0.

Hi Sadique
I'm going to attempt this again. I've installed Xen 3.2 on my CentOS 5.1
machine, and want to try use this jailtime image again.
I've mounted /home/centos.5-1.img on /mnt/vm, edited /mnt/vm/etc/fstab &
changed it to use /dev/xvda1
# This file is edited by fstab-sync - see 'man fstab-sync' for details
/dev/xvda1 / ext3 defaults 1 1
From this, I realize there's no /dev/xvda on the image:
[root@temp01 ~]# ll /mnt/vm/dev/x*
crw-rw---- 1 root root 10, 179 Mar 25 2001 /mnt/vm/dev/xsvc
crw-r--r-- 1 root root 204, 191 Mar 21 2007 /mnt/vm/dev/xvc0
So, how do I get it?
I'm trying to understand what you mean with the --with-xennet
--preload=xenblk stuff, but I don't understand how / where to put it.
Please elaborate?
Yet, when I try and use it, I get the following error:
VFS: Cannot open root device "xvda" or unknown-block(0,0)
Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: Unable to mount root fs on
unknown-block(0,0)
Any ideas on how to get these images to work?
