@jburwell Creating Marvin test for this PR will be a huge undertaking. It
would require building and configuring a hypervisor in a deployed VM and then
creating VM in VM. Considering storage, environmental and network implication
the test will be complicated and error prone. An alternative approach would
require integrating vSphere SDK with Marvin python libraries and query vSphere
for the actual nested virtualization settings from a deployed VM. The effort
doesn't seem to be warranted for such a minor change. As long as standard
integration suite is passing this shouldn't affect any existing functionality.
What do you think?

> h2. Introduction
> It is desired to support nested virtualization at VM level for VMware
> hypervisor. Current behaviour supports enabling/desabling global nested
> virtualization by modifying global config {{'vmware.nested.virtualization'}}.
> It is wished to improve this feature, having control at VM level instead of a
> global control only.
> h2. Proposal
> A new global configuration is added, to enable/disable VM nested
> virtualization control: {{'vmware.nested.virtualization.perVM'}}. Default
> value=false
> h2. Behaviour
> After a vm deployment or start command, vm params include
> {{nestedVirtualizationFlag}} key and its value is:
> * true -> nested virtualization enabled
> * false -> nested virtualization disabled
> We will determinate nested virtualization enabled/disabled by examining:
> * (1) global configuration {{'vmware.nested.virtualization'}} value
> * (2) global configuration {{'vmware.nested.virtualization.perVM'}} value
> * (3) {{'nestedVirtualizationFlag'}} value in {{user_vm_details}} if present,
> null if not.
> Using this 3 values, there are different use cases:
> # (1) = TRUE, (2) = TRUE, (3) is null -> ENABLED
> # (1) = TRUE, (2) = TRUE, (3) = TRUE -> ENABLED
> # (1) = TRUE, (2) = TRUE, (3) = FALSE -> DISABLED
> # (1) = TRUE, (2) = FALSE -> ENABLED
> # (1) = FALSE, (2) = TRUE, (3) is null -> DISABLED
> # (1) = FALSE, (2) = TRUE, (3) = TRUE -> ENABLED
> # (1) = FALSE, (2) = TRUE, (3) = FALSE -> DISABLED
> # (1) = FALSE, (2) = FALSE -> DISABLED
