Mmmm, seems I was mistaken, as it works now. I had the following issue:

kvm: cannot set up guest memory 'pc.ram': Cannot allocate memory
TASK ERROR: start failed: command '/usr/bin/kvm -id 100 -chardev 
'socket,id=qmp,path=/var/run/qemu-server/100.qmp,server,nowait' -mon

But this was with only 4GB of RAM (3GB requested for VM). I fixed this 
changing to 2GB RAM. I would expect this to work, but that's another 
issue :)

I have now 20GB of RAM in that server, and increased VM to 8GB, but the 
first time I wrongly typed 80GB, so I mistakenly thought this was 
because of win10/win8 setting.

Thanks a lot and sorry for the noise!
