Thanks Ian,
I used your example and I get this message now:
[root@keepup1 vms]# xm create -c jnew vmid=1
Using config file "./jnew".
Error: Device 769 (vbd) could not be connected.
Device /root/vms/jnylund2 is mounted in the privileged domain,
and so cannot be mounted by a guest.
My conf file is:
[root@keepup1 vms]# cat jnew
# -*- mode: python; -*-
kernel = "/boot/vmlinuz-2.6.20-1.3002.fc6xen"
memory = 512
name = "jnylund2"
vif = ['bridge=xenbr0' ]
disk = ['phy:/root/vms/jnylund2,hda1,w','phy:/root/vms/j2swap,sda2,w']
ip="*.*.*.*"
netmask="255.255.255.0"
gateway="*.*.*.*"
hostname = "test2.domain.com"
root = "/dev/hda1 ro"
extra = "3"
any ideas?
thanks
Joel

Here is a sample working config file using LVM, I have swapped out

Subject: Re: [Xen-users] how to create a vm from a file system
Hi, I have looked through the manual now, but I still dont get it.
Lets say I have a standard fedora setup running xen kernel & xen
I have a the filesystem I want the vm to use (files given to me from a
previously used vm ) starting with its root starting at (/root/vms/
jnylund2)
My hard drive devices are:
Device Boot Start End Blocks Id System
/dev/sda1 * 1 13 104391 83 Linux
/dev/sda2 14 30401 244091610 8e Linux LVM
I created a config file with the following:
# Kernel image file.
kernel = "vmlinuz-2.6.20-1.3002.fc6xen"
memory =512
name = "jnylund2"
vif = [ '' ]
disk = [ 'phy:sda2,sda2,w' ]
dhcp="dhcp"
hostname= "vm%d" % vmid
#root = "/root/vms/jnylund2"
root = "/dev/sda1 ro"
#extra = "4"
When I try to run:
[root@mymachine vms]# xm create -c j2-conf vmid=1
Using config file "./j2-conf".
Error: int argument required
It doesn't work, and I also dont understand where im supposed to tell
it to use /root/vms/jnylund2 as the root of the virtual machines file
system.
thanks
Joel

Oh, wait. You have to build the file system first, edit /etc/mtab
and /etc/fstab appropriately, make sure your kernel has the
appropriate modules to access the Xen virtual hardware for network
and hard drive controllers, and be prepared to reset all your
SELinux settings.
It's not as easy as many manuals make it out to be. It's often
easiest to actually delete the kernel, and do a Fedora upgrade or
install on top of the existing OS with the virt-install tool.
