It's kind of weird, it's not exactly showing up correctly on my system.

# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/sda1             446G   43G  381G  10% /
tmpfs                 3.9G     0  3.9G   0% /dev/shm

Right here alone, has me kind of sketcy. Total - 446G - 43G should =  
403G
But in var/lib/xen/images.....

# du -sh *
9.8G    ns1.img
9.8G    ns2..img
119M    shared01.img
20G             www.img

Doing the command as you say.....

9.8G -rwxrwxr-x 1 root root 9.8G Jan 28 15:18 ns1.img
9.8G -rwxrwxr-x 1 root root 9.8G Jan 28 15:18 ns2.img
134M -rwxrwxr-x 1 root root  98G Jan 28 15:18 shared01.img
 20G -rwxrwxr-x 1 root root  20G Jan 28 15:18 www.img

I'm just overall kind of confused how this is working.  I should in  
theory be able to over allocate a number of vm's, so that when I get  
close to running out, I can just add more disk space as cash allows.
Thanks,

Charlie
