CL220 lab is broken

Hi everyone,

A node called ose-node.lab.example.com from the lab of CL220 course can't start - the boot process is stuck at "Booting from Hard Disk..." stage, which makes it impossible to complete a lab with creating an OpenShift container provider. There may be more affected labs, but I'm only at the chapter 4 yet. Resetting the node didn't help. Is there anything else that can be done? Thank you in advance.
