How is the virtualisation done?
In which way is OpenVZ virtual server different from dedicated servers?
Kernel/kernel module/ driver: The kernel and kernel modules are predetermined by the host system and cannot be modified by us. Hence some VPN solutions and real-time virus scanners cannot be used, as well as other applications that need certain kernel properties to function. For the same reason it is not possible to install driver software.
- Virtual memory swapping: Only the amount of RAM ordered can be used. Expanding capacity is only possible by changing to a higher product, but not by using a virtual memory swapping.
- Hard drive/partitioning: The server does not visualise a whole hard drive, but makes a virtual data system available. Because of this no partitioning can take place and the data system cannot be changed.
- Operating system versions: Only the operating system version pre-installed by us is supported. An upgrade to a newer version number of the same distribution or the installation of other distributions may be successful in some instances; however, we cannot guarantee this will be the case. For instance, problems may occur if certain components require newer kernel functions/versions than the ones offered by the host system. The virtual server may become damaged and unusable as a result.
- Hostname: A permanent change of the hostname can only be performed by the Support team.
- Performance: As the hardware is utilised by several customers, resources are divided between all systems, so that only a part of the host system’s capacities can be used.
- Virtualisation: You cannot use any virtualisation solutions (VMWare, XEN, ...) within the virtualisation.
- Time: The server’s time is automatically synchronised with a time server and cannot be changed within the virtual server. A configuration of an own NTP client is therefore neither possible nor necessary.
With which operating system does my vServer run?
When ordering you can choose between different Linux distributions. A new installation or an operating system change can be performed via the KeyVZ or you can request the Support Team to do this for you – free of charge. Please remember to secure your data beforehand, as it is deleted during a new installation. A Windows installation is not possible.
Can I change the hostname of my server?
If you have stated a certain server name at the time of placing the order, we will use this name when we install your server; if you haven’t, the server will be given a name following this template: kmXXXXX-XX.keymachine.de, whereby the letters X stand in for any number between 0 and 9. A permanent change afterwards can be requested from our Support Team.
How do I manage my vServer RVS M14?
You can restart, newly install, secure, etc. via the KeyVZ interface, which you access via https://IhreIP:4643. Use your server ID and root password to login.
How is the virtualisation done withe a RVS S14, RVS L14 or RVS G14 server?
Virtualisation is done on the basis of KVM (kernel-based virtual machine) via Proxmox.
What are the advantages of KVM?
By contrast, the advantage of KVM is that is possible to operate almost any number of operating systems without any additional adjustments under one central administration. This operating type is called full virtualisation or Hardware Virtual Machine (HVM). KVM is a hardware virtualisation technology and is available as a kernel module for the Linux kernel. Hence the hypervisor – i.e. the virtualisation software – also runs very close to the hardware. Complete virtual servers (with our own virtual hardware) are provided, in which almost any type of guest operating system can be installed. The virtual machine acts like your own dedicated server with firmly assigned resources. These resources exist in isolation, in contrast to OpenVZ, and cannot be influenced by other virtual servers.
- Hard drive/partitioning: During installation partitions can be set up which can be formatted with any desired number of file systems
- Operating system version: Almost any desired operating system may be installed. The operating system version can be upgraded – the same as for dedicated servers
- Hostname: The hostname can be changed by the user at will
- Performance: The resources are available to the virtual server as dedicated resources and are not influenced by other VPSs
- Virtualisation: Theoretically the installation of another virtualisation within a virtual server is possible. However, we do not recommend doing this.
- Time: The time can be set within the virtual server, for example by using an ntp server
With which operating system is my vServer (RVS S14, RVS L14, RVS G14) run?
When ordering you can choose from different Linux distributions. Retrospectively you may also install any other system of your choice, even Windows, if you hold the respective licence. A new installation can be done via the Proxmox administrative interface.
Can I change the hostname of my server (RVS S14, RVS L14, RVS G14)?
You can change the hostname in the configuration of the installed operating system.
How do I manage my vServer (RVS S14, RVS L14, RVS G14)?
You can manage your virtual server via the Proxmox interface (restarts, new installations, etc.).Use the server ID and the password assigned to you to login.
