The issue got resolved:
First of, I removed the alias entries that I wanted to put to my VM(s) from the host.
Then, I needed to set up my guest's IP according to my provider's instructions. That involved assigning the IP statically to the adapter and alike.
Then, bridge the VM with eth0
. That is fine, because that interface also gets accessed through the IP.
With this done, I can now properly connect to the VM, just like it should be.

Tipp:
I used the VRDP protocol to connect to my VM and set it up. Make sure that the virtual MAC address - or the address that your provider allows you to use - is inserted whilst the VM is offline. You have to do this from your host to ensure that it works as expected. Further, it might confuse you how my provider suggested route add
/route del
for the pre/post scripts. It turns out that this is actually neccessary - and I have no idea why. But it worked that way.
