Can we say xilkernel as RTOS?? Is there any free RTOS available in Spartan 3e or Virtex4....??
Any tutorial or information regarding this will be very helpfull........

That depends on what you consider real time. xilkernel seems to be a preemptive OS, but I do not know how deterministic it is. Another free OS is FreeRTOS (www.freertos.org), which has a port for microblaze. It is licensed using a modified GPL license, meaning you can probably use it without having to disclose your source code.

Here is a good article on RTOS that has the formal definition and some examples.
RTOS-es can be classified as soft real-time and hard-real time. An example of free soft real-time OS that can run on Spartan FPGAs is embedded Linux. For example Petalinux distribution running on a MicroBlaze processor.
I'd speculate that xilkernel is a hard real-time OS (unless this claim is disproved by somebody more knowledgable).
