Installation guide

Clients that ordered a VPS based on the KVM virtualization technique have two ways to install their OS


Using OS Templates:
- This is the easiest and most used way to install an OS

1) Login into the VPS Panel.
2) Navigate to your VPS.
3) Click on "reinstall", and select the OS you prefer, followed by a click on "reinstall".
4) After you have clicked on reinstall, you'll see your new password which is random generated. For security reasons we recommend that you change this password asap.
5) Wait a couple seconds to a few minutes until your IP address pings.

Notes:
All IP addresses assigned to your VPS will be configurated automatically.

Manual install via ISO:
- This is the advanced method, great for clients who profer a custom installation of their OS, or when there is no template available

1) Login into the VPS Panel.
2) Navigate to your VPS.
3) Navigate to 'CD-ROM' and select + mount the ISO image you would like to use.
4) Under 'settings' there is an option to select the 'boot order'. Make sure you set the CD-ROM as first boot device.
5) Click on "reboot", and click on "VNC" after +/- 5 seconds. Your OS installation should begin now.
6) Once the installation is finished, unmount the ISO and set the boot order to Hard Disk. Unmounting the ISO is very important - otherwise your VPS might refuse to boot in the future.

Notes:
a) We recommend to use the "VirtIO" disk driver. Use IDE only when your OS has no support for VirtIO, since IDE much slower compared to VirtIO. All recent OSes have drivers built in to support "VirtIO". Make sure you select the preffered disk driver before installing the OS.
b) Besides the VirtIO disk driver, we also recommend to use the "VirtIO" network driver. The standard Realtek will work fine, however we see some performance gain in network throughput when using the "VirtIO" network driver.
c) During the installation you can use DHCP for internet connectivity. Although we recommend to set the IP details static once the installation is finished.
d) Most operating systems will take care of disk alignment during partitioning. If you use FreeBSD as OS, please manually create partitions based on the 4K sector size and use 1M boundaries, otherwise you can loose I/O performance up to 25 times.
e) Make sure to unmount the ISO after the installation to avoid boot issues in the future.



Network settings:
We recommend to set the IP details static in your network config. When using a OS template, you can skip this since the template will configure everything for you.
IPv4 details:
Gateway: XXX.XXX.XXX.1
Netmask: 255.255.255.0
* Where "XXX" are the first 3 parts of your primary IPv4 address.
* An exception on this are VPSes hosted within the 5.2.65.x range. If you ave a VPS with an IP address from this block; use "5.2.65.129" as gateway, together with "255.255.255.128" as netmask.

IPv6 details:
You can find the IPv6 gateway in the VPS panel by navigating to tab "Network", and click on your IPv6 subnet. This page shows all the details that you'll need to configure IPv6.
Make sure to use the correct netmask!, as you get a subnet assigned from a larget IPv6 block.
- When you have a /64 subnet assigned, use /48 as netmask when configuring IPv6 addresses.
- When you have a /80 subnet assigned, use /64 as netmask when configuring IPv6 addresses.

2a01:1b0:7999:446::1:4


Known issues:
1) In some cases the SWAP partition isn't being created properly. If your VPS shows only <64MB of swap, you might face this problem. Solving this SWAP issue is very easy by entering 3 commands - in the example below '/dev/vda2' is the SWAP partition:
swapoff /dev/vda2
mkswap /dev/vda2
swapon /dev/vda2
