There are lots of virtualization technologies used by hosting-providers for creating VPS nowadays.
The most popular are:
Although the number of platforms is quite big there are only two types of virtualization:
OS-level virtualization is implemented on the physical server's OS kernel-level thus VPS's are able to work only with hosting kernel modifications, while hardware virtualization deals with hardware level dividing one hi-end server into few VPS's with lower performance.
Each virtualization type has it pros and cons. VPS with OS-level virtualization is valued due to competitive pricing and good performance. It takes only a few moments to complete such common actions like installing OS or rebooting the server. The major problem though is possible overlapping of virtual instances while using hardware resources.
Such issue is impossible with hardware-assisted virtualization platforms like:
Average fee for VPS based on hardware virtualization technology is higher than for OS-level based one, but you can't overlook the main benefits – stable performance of each virtual machine is guaranteed while all VPS's are fully independent and not affected by possible excessive load of the neighbor.
