[ale] [OT] VMWare learning environment?

[Tory Deron]

We are experimenting with Nutanix AHV, which is based on Linux KVM, but commercially supported.    From what I’ve seen so far, I expect our relationship with VMware to diminish over the next couple of years as we start to move work loads to AHV.

As far as I can tell, AHV is just an overlay over standard KVM.  I can even connect and manage VMs with Virt-Manager, and other KVM tools.

New host starts new instance, pauses, overlays old instance memory, pauses old and unpauses new. Can't start new with a locked drive to start process. Process continues anyway on shutting down old instance. Demo goes down. Ouch.
