I can't comment on some of the fancier images offered by jailtime, but
for something like Centos (or rhel), I recommend you roll your own
image. I created a local mirror of the Centos 5.1 files, and it takes
about 8 min to do a kickstart installation.
>From what I've learned so far, xvda is provided by the xen block
device driver, which is either in the kernel image, or part of the
initial ramdisk (initrd). I see in your config file you are booting a
special kernel, but without special initrd. Usually they go hand in
hand.
Here is my centos 5.1 xen config file. You'll note I am using an lvm
logical volume as the block device, instead of a loopback file.
# cat netserver
# uncomment the kernel, ramdisk and extra lines for a kickstart install
# make sure to comment the bootloader line
# after the install, comment kernel, ramdisk and extra, uncomment bootloader
#kernel = "/root/xen/centos64-xen-vmlinuz"
#ramdisk = "/root/xen/centos64-xen-initrd.img"
#extra = "text ks=http://192.168.2.8/centos64-2.ks";
bootloader = "/usr/bin/pygrub"
name = "netserver"
memory = "256"
disk = [ 'phy:vg0/xen_netserver,xvda,w', ]
vif = [ 'bridge=xenbr0', ]
vcpus=1
on_reboot = 'restart'
on_crash = 'restart'
on_poweroff = 'restart'
#on_reboot = 'destroy'
#on_crash = 'destroy'
#on_poweroff = 'destroy'
This is the site that taught me how to do a centos domu via kickstart:

Hi Gordon
I actually want to get FreeBSD & Windows working on my CentOS 5.1 x64
server as well, so the jailtime images seem ideal.
I've modied the /etc/xen/centos.5-1.cfg file a bit, and the VPS is
starting up, but haning at the sshd service:
INIT: version 2.86 booting

This is my config:
[root@temp01 ~]# more /etc/xen/centos.5-1.xen3.cfg
kernel = "/boot/vmlinuz-2.6.18-53.1.14.el5xen"
ramdisk = "/boot/xen-guest-initrd"
memory = 512
name = "centos.5-1"
vif = [ '' ]
dhcp = "dhcp"
disk = ['file:/home/centos.5-1.img,xvda1,w', 'file://centos.swap,xvda2,w']
root = "/dev/xvda1 ro"

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?
