Virtuozzo VS Hyper-V - Which is better ?









Being the two commonly used virtualization technologies, Virtuozzo VS Hyper-V is a tough decision to make.

Out of the various virtualization technology available today, it is difficult to select virtualization that matches your current requirement.

Here at Ibmi Media, as part of our Server Management Services, we regularly help our Customers to perform Server Control panel related queries.

In this context, we shall review Virtuozzo and Hyper-V.


Virtuozzo VS Hyper-V

Here is a small comparison between Virtuozzo and Hyper-v, which discuss the key difference between these two virtualization technologies.


1. Operating System-Level Virtualization Technology – Virtuozzo

In OS-level virtualization, creating virtual servers by utilizing a single base operating system with strong resource sharing and isolation for the guest containers is also known as container-based virtualization.

In addition, finite number of resources can allocate to users depending on their needs.

Moreover, we can use it with either a Windows or Linux OS.

In Virtuozzo, all the virtual machines in a hardware node run on the same kernel. Therefore we can create only Linux virtual servers inside a Linux hardware node. So is the case with windows hardware nodes.

Hence, any patch or updates applied to the main hardware node will propagate to all the virtual servers inside it.

A drawback of this technology is that we cannot employ full customization on any particular virtual server.

In the case of a dedicated server, we may want to run multiple OSs (Windows and Linux) on the same server. In such cases, we will not be able to use OS Level Virtualization.

If we require a customized kernel or unique kernel modules on a server, then a Hypervisor VPS is the best suite for your needs.


2. Hypervisor Based Virtualization – Hyper-V

A Hypervisor server employs true virtualization providing each guest virtual machine with its own virtual hardware.

We can install any OS in the virtual server as per our requirements. In addition, we can allocate resources according to our needs.

Since all the virtual machines isolate from each other, we can customize our server and apply security patches without affecting other servers. This is one of the major advantages of it.

A good example of hypervisor-based virtualization is Hyper-V.

The hyper-v servers are basically windows VPS and we use Hyper-V Manager to manage the VPS on a hardware node.

In hyper-v servers, the resource assigned to a VPS is specific to that VPS and will no other VPS will use it on the hardware node. This ensures better performance on the VPS.


When to use a Virtuozzo VPS?

1. Lower disk and memory consumption.

2. Cost-effectiveness.

3. Windows VPS and Linux VPS.

4. Higher VPS density and more efficient usage of resources.

5. Patches are applied automatically on all VPS.


When to use a hypervisor VPS?

1. To run multiple OS on a dedicated server.

2. Customized kernel or unique kernel modules.

3. Guaranteed performance.

4. Windows VPS.

5. Full control of all updates and patches.

Conclusion

This article covers some comparison between Virtuozzo VS Hyper-V. 

Hyper-V and Virtuozzo are both popular VPS platforms used by a large number of web hosting providers for the provisioning of Windows VPS hosting services, with Virtuozzo being favoured for Windows Server 2003 VPS hosting and Hyper-V being the most reliable solution for Windows Server 2008 VPS hosting services.


Advantages of using Virtuozzo over Hyper-V include:

1. Direct Linux support – Virtuozzo can be installed on their Windows or Linux VPS hosting nodes, and although Hyper-V can be used for the hosting of virtual machines running Linux it is only available for use on Windows Server 2008.

2. Web based control panel (Parallels Power Panel) – the Parallels Power Panel will allow users to manage their Linux or Windows VPS hosting server from a web based interface meaning that if they aren't in a situation where they can access their VPS server via Remote Desktop then they can use the Power Panel to restart their VPS server if necessary or to kill any services or processes which may be overloading their VPS server’s resources.

3. Separate application – the fact that Virtuozzo is a separate application which can be installed on top of the operating system can have its advantages in some cases, for example if a web hosting providers wishes to discontinue using a server for VPS server hosting then all they have to do is uninstall the application from their server, although in most cases it is advised to do an OS reload anyway to ensure that you have a blank canvas to start with.


Advantages of using Hyper-V over Virtuozzo:

1. Cost – with Virtuozzo VPS hosting web hosting providers have to pay for the cost of the Virtuozzo application and the cost of the operating system license, but because Hyper-V is part of the Windows Server 2008 operating system they will only need to pay for the operating system license – this can help to reduce the costs of Hyper-V VPS hosting services and as the cost of the operating system falls, prices will fall further and will eventually meet Virtuozzo Windows Server 2003 hosting services when it comes to price which will mean that people will gradually move over to using Windows Server 2008 VPS hosting.

2. Reliability – as Hyper-V is part of the Window Server 2008 operating system, web hosting providers are able to guarantee reliable Windows Server 2008 VPS server hosting services.

3. Native support for Windows Server 2008 – although Virtuozzo may have support for Windows Server 2008, it hasn’t been able to offer the most reliable of Windows Server 2008 VPS hosting services.
