A given image is pushed to hub twice, once as
kernel:<kernel version>.<major version>.x and once as
kernel:<kernel version>.<major version>.<minor version>-<n>.
The latter is used to decide if a new kernel image is pushed to hub.
Most users should use the former to pick up the latest kernel.

LTP is compiled in on debian container and the binaries
then copied into another container, which is pushed to hub.
LTP does not compile on Alpine as it uses glibc specific
pthread extensions.
I tried to link LTP statically to not require a glibc based
base image but that failed too.

Passing accel=kvm:tcg causes it to try KVM first if available with a fallback
to TCG (emulated/JIT mode) if it is not available. With this the boot logs gain:
+Hypervisor detected: KVM
and also
-Booting paravirtualized kernel on bare hardware
+Booting paravirtualized kernel on KVM
Among various other noise.
If I rename my host /dev/kvm then this is reversed, although with the following
message:
Could not access KVM kernel module: No such file or directory
failed to initialize KVM: No such file or directory
Back to tcg accelerator.
Q35 is a more modern emulated platform based on the ICH9 host chipset rather
than the default "pc" I440FX (Pentium Pro / Pentium II era) emulation. See
http://wiki.qemu-project.org/Features/Q35 for more info. Switching to Q35 is
not a requirement for enabling KVM but seemed like a reasonable change.

- Currently only works if you add your ssh key in the example yaml, but will replace
with metadata support shortly.
- sshd logging not yet configured (needs to share syslog socket).

- these were set via the Alpine config file previously.
- removed `kernel.panic` as we have decided to avoid reboot on panic.

- VHD is uncompressed VHD. Currently hard coded at 1GB, which may need to change. Use `format: vhd`
- GCE is the GCE compressed tarred raw image. Use `format: gce-img` - reserving `gce` for actually
uploading the image.

- in a much better state than previous commit, but still some issues
running system containers with it that need more work, so staying with `runc`.

os.FindProcess() does not return an error when then process does not
exist. It even returns a dummy process object.
Use the go-ps package to find out if the hyperkit process is actually
running.
