Odd, please step back, why have you determined that this is something
that you have to do?  Were you told to do this by someone?  Is this a
homework assignment?  What problems are you thinking that this might
help with?

And please define "VM" here, what exactly is that?  A KVM image?  Xen?
Hyper-V?  Something else?

thanks,
