With many thanks, this comes from @yupavlen-ms's PR #1190 . Other parts of his PR have been split out or handed in different ways.

TODO:

  • Validate the two remaining entries (could be ...)
  • Some additional comments cleanup
  • Make sure I'm handling the Some/None in openhcl_boot appropriately
  • VMM tests
    • allow changing vtl2 memory/openvmm (pr approved)
    • allow changing vtl2 memory/hyper-v (not started yet)
    • discern dev/release runs (dev profiles require more memory per json)

petri: allow test to override default VTL2 allocation scheme (#2224)
83bccbf 
Promote the settings that change how VTL2 memory is allocated to the
Petri VM objects, rather than being hidden in the depths of the OpenVMM
config. This is a convenience for additional tests coming as part of
#2215 .
