It is perfectly possible to *recompile* a kernel within a vserver, compiling
is as normal as any other process.

There is only *one* kernel in the system. The kernel that the vserver is
talking to is the same one that processes in the host server are talking to,
it is just that they cannot see each other.
Upgrading the kernel on the host server is therefore upgrading the kernel
for everyone.
If you really want to run seperate kernels you either need to run a
full-blown emulator/virtual-machine setup such as Bochs and VMware; or run
User Mode Linux (UML) to give you a second, seperate kernel and operating
environment running within the first, boot kernel.
Both this are significately slower which is why vserver "is so great!".
