Sure, PROBES as an VM in e.g. overloaded environments are a problem.

So Probes on a VM = can result in some troubles in the existing Atlas model.

To make a "second class" probes I agree that this takes too much efforts.

ANCHOR as an VM would really make sense.

What do you think about this ?

PACKAGES for an OS I see too much dependencies / problems incoming.

So a VM with an isolated OS for this usage makes sense.

Just my 2 cents .-)

Hello,

As a researcher, I will have to filter out these VM probes unless there
is considerable evidence that VM probes are able to produce results
comparable to hardware probes. Note, calibrating probes is really
hard and it takes time and effort [1, 2].

The idea of using these VM probes for "second-rate monitoring” is also
less useful because it leads to fragmentation of RIPE Atlas vantage points.

I am completely in line with Daniel’s view — the novelty of RIPE Atlas
is being able to produce repeatable / comparable results. We should
not compromise this unique standpoint.
