+For this challenge, your team must live migrate the virtual machine named `fedora` in namespace `demotestwtf17` from one node to another and record the name of the node the vm has migrated to.
 
 No command line is required. However before you can complete the migration you will first need to investigate and correct why the virtual machine is not running. You had one too many coke zeros last night and can't remember how you got the machine into the state it's in 🤦.

-Acme Financial Services have agreed to run a small scale proof of concept for OpenShift Virtualisation.
-
-They have spun up a bare metal OpenShift cluster, installed OpenShift Virtualisation and now have a small number of virtual machines running.
-
-One of the goals of the pilot is to ensure their virtual machine workloads will run efficiently on their new infrastructure and continually auto balance over time based on available underlying infrastructure capacity so they don't have some nodes much busier than others.
-
-The Acme team are stuck on how they might implement this goal within the poc. They told you they found some documentation online on this thing called "deschedular" but didn't have any luck setting it up.

-Your pre-sales team have offered to setup an example environment for them and give them a quick demo on how it works.
