[PATCH 2/2] kvm tools: Print out important command line options at startup

[Pekka Enberg <penberg@kernel.org>]

It's important to know what the guest configuration looks like when debugging
issues so print out important command line options at startup:

  $ ./kvm run -k ../../arch/x86/boot/bzImage -m 512
    # kvm run -k ../../arch/x86/boot/bzImage -m 512 -c 1
