I am trying to create a para-virtualized guest with the same
kernel image and initrd image as dom0.
The configuration is below
================================================================================
kernel = "/boot/vmlinuz-2.6.21.7-3.fc8xen"
ramdisk = "/boot/initrd-2.6.21.7-3.fc8xen.img"
memory = 428
name = "fedora.fc8"
vif = [ '' ]
dhcp = ""
disk =
['tap:aio:/var/lib/xen/images/fedora.fc8.img,xvda1,w',
'tap:aio:/var/lib/xen/images/fedora.swap,xvda2,w']
root = "/xvda1 ro"
================================================================================
The file system and swap images are downloaded from
jailtime.org.
But while creating a domain the guest crashes and here is
what it has to say
=========================================================================================================================
[root@localhost Desktop]# xm create
fedora.fc8.xen3.cfg -c
Using config file "./fedora.fc8.xen3.cfg".

Looks like it is not able to find root file system to mount.
