Download and startup of the machine went smooth as expected. The machine is running in a host-only network and got the IP address 192.168.56.101 assigned. The host's virtual network interface is 192.168.56.1.
General remark: You may experience problems with the VM at times. It may become unresponsive or one of the payloads you used won't work anymore. From my observations this becomes very likely if you are using brute force techniques. These will fill up the logs and exhaust disk space up to the degree where the machine can't even store sessions anymore which will prevent you from logging in. If that happens restart the machine, that did fix the issue for me most of the times. At one point though, only rolling back to a previous snapshot solved my issues.
