   You might try the 4.9.110-3 kernel from stretch-proposed-updates,
  which I noticed is required to fix a reboot-loop on stretch:

 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=903767

   That doesn't seem to match your situation 100% as you do
  seem to gain access, albeit briefly, but it might be worth a go.

I've noticied that, and tried to run 4.9.110-3+deb9u2 as 4.9.110-3 is 
out from stretch-proposed-updates.
I ran 4.9.110-3 too, same problem. (and almost every 4.9 version that 
where in repo since stretch is out, got a freeze each time, had to 
fallback each time)



When running on jessie's 3.16 kernel, the guest is running fine.
I have other VMs on this host running 4.9 kernel without problem.


   It is interesting that not all guests fail ..

Indeed, it is. But I don't figure WHY this guest fails. And as it's the 
"put-it-here-if-there-is-no-obvious-choice" machine of my network, 
there's many installed services on it.
