Your price criteria is quite demanding (what you're looking for tends to be 1800+ Euro), but the short quick answer would be http://www.pcspecialist.co.uk/notebooks/defianceII-15/
6th Gen Intel i7 Quad Core 8 Thread 6700HQ, has Vt-x and VT-d
GeForce GTX 965M 2GB Graphics Card
32GB (4x8GB) 2133MHz DDR4 Memory installed-supports 64GB
3 year standard warranty
15.6" Matte Full HD IPS
Backlit Keyboard (very very nice)
4 x USB 3.0
HDMI Output Connection & Mini Display Port
Intel AC8260 (867Mbps) M.2 Wireless and Bluetooth
with a 500GB HDD (36 Euro) and Windows 10 (106 Euro) and delivery to EU (26 Euro-they do deliver elsewhere) comes to a total of 1334 Euro. Using their configurator you could remove Windows 10 for a Linux distro and replace the HDD with a 240GB SSD for 1284 Euro. If you need Windows you could install that later as a host OS or a VM. At the same time It's a very good graphics card and to utilize it fully with Direct X (to play some games too), maybe buy a standalone Windows license. As opposed to an OEM Windows license, which only allows you to use Windows on that machine (hard install or VM), you can easily move Windows to any another machine (physical or VM). Highly recommended to buy the HDD caddy too.
If you know you need 32GB this is the system I would recommend, as it exceeds both your required (2133 MHz DDR4 RAM, I assume you would have been happy with 1600MHz DDR3L) and not required (gaming graphics) specs. It'll easily destroy any common VM setup. Should handle any personal cloud computing stuff, obviously depends on the stuff. I'd leave server stuff to servers, again depending on end use, a small server shouldn't be too much of a problem.
Another (possibly cheaper) Option:
You would want an i7 with virtualization support i.e VT-x (either 5th or 6th Gen) but are you sure you really need 32GB? You could get a dual core, four threaded i7 machine with 8-16GB with at least 2 RAM slots and pretty good graphics for 700-1000 Euro. 16GB is a lot of memory for running VMs. For example you could buy a 16GB machine easily for under 1000 Euro and try it. If you actually do need more RAM you could upgrade and you wouldn't necessarily be limited by 2 RAM slots (4 slots is obviously preferable). SODIMM RAM on laptops is usually limited to 8GB due to specification, however a clever company called Intelligent Memory has managed to stack a massive 16GB DDR3 on a single stick! So even with only 2 RAM slots you can reach 32GB.You can get them at amazon.de all you need is any 5th (Intelligent Memory) or 6th (PACCOM) Intel CPU, which you'll already have.
