Virtualbox (5.2.44) installiert, Prozessor besitzt hardwareseitige Unterstützung für Virtualisierung und diese ist aktiviert

Have now installed Virtualbox 5.2.44 on this PC, running ftm two Atlas from production and
waiting for some tasks from -dev.

Is it possible, because of 5.2.32 in the Atlas.vdi?

If this is a Factor for postponed, then we need to upgrade it in the .vdi, but therefore
we need some -dev tasks to test it now.

Seeing this in Theory on Production.

As expected, no postponed to run Atlas or Theory in -dev AND Atlas from Production in Combination.
So, Virtualbox 5.2.44 is the only Version running both in this Constellation.

Don't know, what change made this problem with newer Virtualbox-Versions.
