Enable the VM debug console whenever the VM Kernel debug
is enabled.

Fixes: #559.

Has a dependency on having a updated agent being installed in the container rootfs to add the new systemd services.

clearcontainers/agent#122

CI is failing though. I suspect we probably have a vendor or merge dep? In f26 we have:

../../../go/src/github.com/clearcontainers/runtime/list.go:84: undefined: defaultRootDirectory
../../../go/src/github.com/clearcontainers/runtime/main.go:91: undefined: defaultRootDirectory
../../../go/src/github.com/clearcontainers/runtime/config.go:146: too many errors

Hmm, actually the CI run was successful for all 3 runs. Looks like there might be an issue with the jenkins-github plugin @sboeuf ?

@grahamwhaley - the undefined errors are caused by the jenkins scripts incorrectly go get'ing the runtime code (it should be go get -d). Hopefully we can resolve that once clearcontainers/jenkins#10 lands.

Hi @mcastelino - this requires an update to the tests. From the CI logs:

./create_test.go:848: cannot use func literal (type func(string) []virtcontainers.Param) as type func(string, oci.RuntimeConfig) []virtcontainers.Param in assignment

Can you add a $ prompt for consistency with the rest of the doc please. Also, presumably we need a sudo in there too?

@iphutch - please can you review these doc changes?

Hi @mcastelino - just one final nit in the docs from me.

We should avoid using an "if" clause unless we provide options for when the kernel does not boot successfully.
Let us ensure that our instructions are accurate and assume the reader has followed the instructions exactly:
After the kernel boots, the virtual machine console can be accessed for further debugging.

Hi @klynnrif, @rcaballeromx - I'm assuming @iphutch won't be able to complete this review so could one of you take a look and if you're happy, we'll force-merge this as we will have the requisite doc team approval.
