They were created and started with the same version of Xen on the same host,
just a few minutes before saving them.
I wanted to try out the features of Xen and there it happened. The error is
reproducable.
Here is my config file:
------------------------------------------------------------
# Automatically generated xen config file
name = "tom1"
memory = "256"
disk = [''file:/data/vdisks/tom1-rhel4.img,hda1,w'']
kernel = "/boot/vmlinuz-2.6.12.6-xen3_12.1_rhel4.1"
root = "/dev/hda1"
extra = "ro selinux=0 3"
vif = [ ''ip=10.0.10.1'' ]
-------------------------------------------------------------

Michael
