[c-nsp] IOS XRv in a virtual environment

Hi Aaron,

How much RAM has been assigned to this Virtual Machine by your Linux engineer?

On my laptop with 4GB RAM, if I assign 2GB to an IOS-XRv VM it will
run but has periodic memory dumps. On my desktop with many GBs of RAM
(can't remember how much I have assigned to the IOS-XRv VM on their)
it doesn't.

Cheers,
James.
