Yeah yeah, but don't knock it till you really tried.

I pooh-poohed the availability manager notion for a decade before
finally it clicked (Het kwartje viel).

Oddly enough it was right after finally install Personal Alpha on my
laptop.
It seemed a good idea to be able to look back into itself using
Availability Manager.
What else was I actually going to 'do' with it?  (1)

Sure enough, after a little poking with a loop-back connector driver,
and maybe a (software) network bridge it all worked.
I thought it was pretty cool to have a console, a telnet session, and
an outside monitor tool looking at my this non-existing Alpha.
Next I enabled it on my oher servers and voila!

I may or may not work on Linux or Mac. It's mostly (only?) Java best I
can tell.
But I would take te road of least resistance which for me means to
take a crappy PC with a reasonable network card and allow it to run
(not-)OS you love to hate, disabling all the clutter it can bring.
Then RDP into that from your favourite desktop.
I suspect using a VM solution will be tricky as Availability Manager
uses a private wire protocol with broadcasts and stuff.

(1) I end up using the Personal Alpha a lot more than I expected
A) Simple command (help) verification
B) Crash and burn tests, like recently for

C) Demonstrate OpenVMS to the uninitiated masses out there

Hein.
