I forgot to say that I had added support for simulating a CPU topology
with the vkernels.

Usage: ./kernel [-hsUv] [-c file] [-e name=value:name=value:...]
        [-i file] [-I interface[:address1[:address2][/netmask]]] [-l cpulock]
        [-m size] [-n numcpus[:lbits[:cbits]]]
        [-p file] [-r file]
For details about lbits/cbits (logical/core bits): man vkernel.

Thanks,
Mihai
