- It is NOT the same as the server kernel, it is significantly stripped down and lacks a large number of hardware drivers for devices that would not normally be seen in a virtual environment.
- It IS designed for server virtualization, certainly... which is what the vast majority of users would be using it for. Desktop virtualization is the special/unusual case, not server virtualization.
Per the Ubuntu Server FAQ:
What are the differences between the server and virtual kernels?
The difference between the Virtual and Server kernels is that the Virtual kernel is intended to be utilized inside a virtual machine. The virtual kernel only includes the necessary drivers to run inside popular virtualization technologies such as KVM, Xen, and VMWare. The server kernel in contrast contains the necessary drivers to work with a wide range of hardware, and should be installed directly on host systems. Other than that, all other options are identical between the server and the virtual kernel.
