but after import in 3.6.1 I see it configured as with spice console in web admin gui.

I indeed am able to access it via spice, but just to notice that if one eventually would like to have it vnc, he/she has to edit the engine vm

That smells like a setup bug... Simone did you ever see that?
 

after update to 3.6.1.....

BTW: is it possible/supported to edit engine vm from the gui and change for example the console mode?

yes, in 3.6.2
