Various Virtualization Technologies for VPS

Scopehosts provides the VPS hosting service on various virtulization technologies as follows:

- OpenVZ (Open Virtuozzo)
- XEN-PV (ParaVirtulization)
- XEN-HVM (Hardware Virtual Machine)
- KVM (Kernal-based Virtual Machine)

OpenVZ (Open Virtuozzo) is an application based Virtualization Technology mounted on the base Linux kernel and operating system. OpenVZ allows a physical server to run multiple isolated operating system within a separate environment, called containers, virtual private servers (VPSs).

Features

- Low Price and no complication
- Better Performance than Shared Hosting
- Scale Up without reboot needed
- Container based VPS with shared resource
- Reliable for Active website with good traffic.
- Self Managed with Remote Panel

OpenVZ has burstable memory which can be used by multiple virtual Environments only when it is available to use on Main server.  OpenVZ VPS are most suitable for the clients who are surfing for solid performance at affordable price.

XEN-PV and XEN-HVM
XEN is a New and most popular Virtualization , that has an hypervisor on  microkernel to reach out the better performance of multiple Operating Systems to run their Applications on Same Computer Hardware at a time. XEN requires highly privileged CPU state to run the application. It supports both operating systems like LINUX and WINDOWS.

Here Hypervisor plays an important role, that contains the allocation of the resources among the virtual machines presently running on Main Machine like Memory allocation / management, CPU of all virtual machines and creates the Most privileged domain(dom0) which will have direct root access to machine hardware by default and a unprivileged Domain(domU). The Resources are  dedicated to all the virtual machines running on machine. XEN is featured with maximum of Configurable options.

Features:
- 100% Dedicated Resource
- Own kernel and isolated environment
- 99% similar to dedicated server
- Overselling of resource impossible
- Suitable for High Traffic and Disk load usage
- Self Managed with Remote Panel.

XEN has SWAP memory allocation, helps to free up the RAM, XEN allows user to experience the high performance. As it has SWAP memory allocation, leads to run many applications on VPS at an Extreme Load. XEN Virtualization is suitable for the one who is more concern about VPS stability and Higher performance rather than Cost.


KVM

KVM Virtualization is the leading open source complete virtualization solution on x86 hardware and it supports all major operating systems including Linux and Windows, KVM hypervisor is a program that allows multiple operating systems to share a single hardware host. In KVM, the Linux kernel acts as a Type 2 Hypervisor, streamlining management and improving performance in virtual environments.

Features:
- A Full Hardware Virtualization

- Wide range of Linux distros with any kernel
- VM with own virtualised hardwares
- Overselling of resource impossible
- Enterprise applications can be hosted
- Self Managed with Remote Panel
