[Xen-users] After migration from 2.0 to 3.0: Unable to reboot VMs

[<HSeffler@xxxxxxxx>]

Hi,

I am migrating from a xen 2.0 setup to a new one based on xen 3.0. In both 
cases basically the same setup of debian sarge is used as dom0.

Images created for the xen 2.0-machine are working fine except one thing: the 
VMs do not come back after a reboot from within the VM or by 'xm reboot <name>'.

A configuration looks like this:

kernel = "/boot/vmlinuz-2.6.12-xenU"
memory = 400
name = "xen000"
nics = 1
vif = [ 'mac=aa:00:00:00:00:11, bridge=xenbr0' ]
root = "/dev/hda1 ro"
disk = [ 'file:/xen/xen000.img,hda1,w', 'file:/xen/xen000-swap.img,hda2,w' ]

The logs shows:
