[Xen-users] xen live CD demo

[Arijit Ganguly <aganguly@xxxxxxxxx>]

All, 

I was looking at the scripts available to create new domains when I
boot up from the Xen live CD. There are scripts in /sbin with names
start_debian.sh
start_netbsd.sh 
etc.
I started on a few domains. These scripts specify a COW file system for the disk. 

I was wondering if such support is already there in Xen. Allowing
different domains to share a common root file system, and storing
differences in local copies. 

I could find it in demo CD basd on Xen 2.0.5 and not in the Xen 2.0.7 that I have. 

The problem is it takes a lot of time/space to clone a Vm if each has an independent root disk.
