This warning is normal for compute nodes that are slow to boot an
instance. As it states, it is "Retrying".
I would wait a while and see if the compute service will finish
booting the instance. You can also watch it progress by using the
compute console.

If you are running this compute node inside virtualbox or on some
other nested virtualization (without vmx/smx support) scenario nova
can take up to 18-20 minutes to fully boot an instance.

If the instance does not finish booting and this times out, the load
balancer will go into an ERROR state. If that is the case, we will
have to debug nova and the image you are using.
