xen reset guest root password

[unclecameron]

I need to reset a root password on a xen guest DOMU, does anyone know how to reset it some other way besides remounting the vm and chrooting into it? I'm not confident I know the commands involved in doing that. Otherwise, does someone have the commands I need to use?

This is how i did it on my centos xen install. This may or may not work for you depending on how your domU is setup.
