Virtualization technology

What is the difference between virtualization technique and a hypervisor? Are they both means the same?

Hello,

I'll take a shortcut by saying hypervisor is the OS installed on a server hosting virtual machines.

2nd shortcut, virtualization technique is more referring to how the hypervisor emulates its hardware to simulate a hardware config for the vm OS. This way vm OS runs quiet much as if it was running on a physical server.

In simple words, Hypervisor is a software which is used to create or run Virtual Machines. Its also called as a Virtual Machine Monitor.

Using Hypervisor on physical server, one can run different operating systems (like Linux, Windows etc) on virtualized hardware resources.

Pete already explained Virtualization Technique in his reply. 🙂

Hello,

Most common virtulization in market now a days.

OpenVZ & KVM

OpenVZ is a container style of virtualization which relies on the host node's kernel. KVM has no restrictions in terms of functionality, but it has more overhead than OpenVZ. OpenVZ is constrained by the host node kernel, but it has less overhead in the containers themselves. KVM is generally more stable than OpenVZ.

Just FYI as well, OpenVZ only supports linux distros. So if at some point you want to run Windows VM's you may want to consider KVM. We use KVM with SolusVM for a control panel just to make life a bit easier.
