Can I build custom Kernel on my VPS ? (virtual servers)
The answer is YES, We run Xen® hypervisor as a base for our VPS, this is the closest type of virtulization to a real dedicated server.
You can build a custom Xen kernel from source.
The advantage to building the Xen kernel from source is that you can add, or remove, drivers - so the kernel is utterly customised for your system.
