Benifits of VPS over Dedicated Servers and Shared Hosting
Some info on VPS (Virtual Private Server)
Virtual Private Servers are the most advanced step in server virtualization technology.
They are used to partition a single physical server into many isolated virtual private servers.
Each virtual private server looks and behaves exactly like a real networked server system,
complete with its own set of init scripts, users, processes, filesystems, etc.
Appears to have its own processes, users, files and provides full root access
Each has its own IP addresses, port numbers, tables, filtering and routing rules
Each can have its own configuration files for the system and app software
Each can have its own versions of system libraries or modify existing ones
Each can delete, add, modify any file, including files in /root, and install its own application software or custom configure/modify root application software
VPS has five main benefits over a dedicated server:
A virtual private server gives you the functionality of a dedicated server at a fraction of the cost.
With a virtual private server you get built in incremental backups on top of a world class RAID 5 array to ensure data integrity.
The nature of a virtual private server means we can manage all aspects of software upgrading and patching, no need to worry about updating your packages it is all controlled by us.
A virtual private server is functionally equal to a dedicated server.
You get the resources you need when you need them and all resource guarantees are instantly scalable to suit your needs as you grow.
VPS has four main benefits over shared hosting:
A virtual private server gives you root access to the system, this allows you to modify server configuration files, install applications or modify system software, in a shared environment you have to rely on server settings that are 'best fit' for all clients and this may not suit your needs.
With a virtual private server your file system is not accessible or viewable by any other VPS owner, unlike a shared envoronment where anyone with shell access can browse through your files a VPS ensures full privacy and security.
In a shared hosting environment you are 'held hostage' to the actions of others, if another shared account runs a script that crashes the server then your site goes down too. With a virtual private server you have complete resource isolation, no matter what another VPS user does it will not affect your server.
In a shared environment resources goes to the site 'that shouts the loudest' in other words a big site can drain all resources and leave yours performing badly. In a virtual private server environment you are guaranteed a set of resources to ensure your site always performs at full speed, these resource guarantees ensure other virtual private servers have no affect on the performance of your site

VPS surely is good option for small hosting or medium sized web applications. The only drawback is when u need custom kernel modules for some of your applications, which cannot be loaded.

You can on Xen, openvz & virtuozzo shares the host node's kernel.

SelectByte is correct.
On Xen and I believe VMWare, you can have custom kernel compiles (along with your OS of choice). With VZ based systems, you're limited in what you can do, however the performance is slightly better (depending on implementation).
