I'm working on an issue we noticed in openstack where setting the root password 
on a CentOS 6 image through the XenAPI would corrupt the guest image's 
/etc/shadow file.

1. set the root password through XenAPI
2. log in to the account
3. `passwd` -- you should get an error.

To fix you can `rm /etc/shadow; pwconv`

I've tested against an Ubuntu XCP image and everything is fine there… seems to 
only affect CentOS 6
