Hi,
One more query. When i had build the source code of the xen
hypervisor (make world) it had build the linux kernel also(downloaded
the bits using mercurial).
Would it be possible to just build the hypervisor ?
Isn't the hypervisor and linux kernel linked ? Pardon my ignorance.
Like is the linux kernel which is used is specially build to work
with the hyper visor or i can i can build any version of the kernel
and it should work with the hypervisor.
thanks
