We offer two virtualization platforms. These are KVM and OpenVZ.
KVM products are based on the so called KVM hypervisor and provide full hardware virtualization (sometimes called "bare metal virtualization"). Almost every operating system (Linux distros, FreeBSD, Microsoft Windows, ...) can be installed. Each KVM server provides 1 virtual CPU core @2.5 GHz. Compared to OpenVZ products, the virtualization overhead is about 30% higher - that's the reason why this product is slightly more expensive than OpenVZ series products.
- TUN/TAP devices are available
- you are able to run every kind of networking services (VPN, ...)
- Runs every kind of admin-panel like cPanel, DirectAdmin, Odin Plesk panel and more.
- A second virtual NIC can be added
- KVM can be compared to a real hardware dedicated server.
- Operating systems can be installed at the touch of a button - through one-click-installation or manually in a VNC session (similar to remote desktop).
- If the server is idle, the load is 0 (this is important for the comparison of the 2 technologies).
OpenVZ (OVZ) is a "context virtualization" platform. This means these are are not real servers, but hidden tasks in a large Linux mainframe. User feels driving a real speedy dedicated server - with minor limitations. Enjoy full root access to the server and install all the software you need. Network resources are shared! This means you don't have full access to all network settings and iptables rules can only be added in a web-frontend. Not all cpu cores are shared across the entire hostnode, but only 2 vcores (depending on the plan you picked). OpenVZ plans are managed using solusVM control-panel. btw: OpenVZ is compatible with cPanel. Operating systems can be installed at the touch of a button. Installation completes faster than on KVM. Due to a much smaller virtualization footprint, OpenVZ products are cheaper than KVM products.
