Do be clarify: you want virtualisation environment, hypervisor? If yes, then you can go with VMWare ESXi or Proxmox. Both have web based consoles to add and manage virtual machines. Like you mentioned, you need additional IP-s, Hetzner has 6 (/29) for €6.72 per month [0], OVH has one time fee €2.00 per additional IP[1].
