Virtualization Solutions
The network setup of all virtualization solutions is similar. Depending on the software, one or more variants are possible
- Bridged
- Routed
- NAT
Single IPs
For the use of additional single-IPs in bridged mode virtual MAC addresses need to requested. You can get a MAC address for your additional single IP through Robot. Simply login, select your server and then go to the "IPs" tab. Here you will see a small button next to the additional single IP address. Clicking on that button will give the IP address a virtual MAC.
Virtual MAC addresses can only be requested for individual IPs, not for subnets.
| Bridged | Routed | NAT | Special | |
|---|---|---|---|---|
| Linux KVM (also Proxmox) / Xen | x | x | x | - |
| OpenVZ (also Proxmox) / Virtuozzo | x[1] | x[1] | x[1] | x[2] |
| VMware ESXi | x | |||
| Microsoft Hyper-V | x | x[3] | x[3] |
- applies only to veth devices
- applies only to venet devices
- Requires RRAS (Routing and Remote Access) services
Subnets
For the use of IPs in a subnet with a virtualization solution that does not have routing capabilities a VM is necessary to perform this function. The subnet must then be routed on this VM.
| Direct Routing | Router VM | |
|---|---|---|
| Linux KVM (also Proxmox) / Xen | x | (x) |
| OpenVZ (also Proxmox) / Virtuozzo | x | (x) |
| VMware ESXi | x | |
| Microsoft Hyper-V | x | (x) |
(x) - Use of a router VM possible, but not necessary
