What I'm looking to do is set the ExtensionData.Summary.RebootRequired of a VMHost object to true on demand. The reason is then I can have a script that makes a setting change and trigger this flag, then I can have a generic script just look for hosts with the flag, instead of having to be very specific about this host or that host. It seems in some cases, like pushing firmware and drivers from HPe's SPP application this flag get's set, but I cannot figure out for the life of me how to do that. I would even use something ESXCLI based if needbe, but I'm hoping it's not some hidden, partner only API. I also need this backwards compatible back to vSphere 6.0, up through 6.7.
