Looks like the news exposure hit this beta project rather hard they’ve had to stop issuing work for the moment!
So I guess that renders moot me about to ask about typical ram usage and unit run times. I’ll still look to give it a go when I get home, if its up by then.
hmmm… Linux… Virtualbox… headless nodes …
Surpose you sacrifice a bit of performance but save alot of cash only requiring network bootable boards and no Wins licences.
Still keeping up to date with the project news, they’re working on the issues and restated the project is in beta. So the number of users they have right now is more than enough for them. So I’d let their willing volunteers iron out the bugs before I join later. More docking for now 
Yes, lots of bugs at the moment - not a project that you want to involve your machine in if you already run VMs under VirtualBox - seems that it deletes the descriptors for the existing installations.
