Which virtualization method are we using?
We use a real full-virtualization, also known as bare-metal virtualization, for our virtual servers, which offers very high performance and security. In contrast to other virtualization products, you have an independent server instance, which completely isolates you from other customers.
Our full virtualization emulates a complete computer with virtual hardware, which can be addressed by the guest operating system like real hardware. Thereby, the layer of the guest operating system is dispensed with and the commands of the individual fully encapsulated virtual servers are forwarded directly to the hardware. Due to the fact that the commands are directly forwarded and do not have to be processed additionally, full virtualization has a very high performance. Therefore, you can also install and operate unmodified operating systems.
By default, we provide you with a large selection of Linux distributions and versions. You can also select from many versions for the operating system Windows.
Can I run a VPN on my server?
Yes, a VPN can be set up and operated on a Linux as well as a Windows Virtual Server.
For the Windows Virtual Server, the use of PPTP is the easiest method to build a VPN. This connection type is not as secure as L2TP or IPsec, but it is sufficient for many applications.
PPTP-based VPN traffic consists of a TCP connection to the TCP port 1723 on the VPN server and GRE (Generic Routing Encapsulation) -coded packets for the VPN data. However, PPTP traffic can cause problems with firewalls, NATs, and web proxies. To avoid this, firewalls must be configured to allow both the TCP connection and GRE-encapsulated data.
With Linux Virtual Server, For example, the tunnels are built using OpenVPN.

Can I use a custom kernel?
Yes, you can use any kernel you want. We offer you a large selection of Linux distributions or different versions of Windows. If the operating system you are looking for is not listed, please let us know. Mail to Online Support.
We are using a real virtualization for our virtual servers (KVM). You can also use unmodified kernels.
