Hey Drew,
Unfortunately, I had to tear down the system and did not get an exact SHA or get logs from the nfs-provisioner. I was not using any custom images. That said, I was finally able to get up and running after another full reinstall (SHA 40797b9d44d2e3ccced0ce2d31b8e2a839a34361). I have only done limited interactions, but all the dashboards seem to be up and will give me a chance to evaluate the system.
Just in case any one else hits this kind of issue, one problem I had noticed before teardown was a lot of openstack components stuck in early init phases or in ImagePullBackOff. Checking their state through `kubectl describe pod` showed connection timeouts, TLS handshake timeouts, etc. When trying to manually pull the images in the VM I noticed the download and extract rate was painfully slow (and quite a bit slower than running directly on the host). This led me down the route of looking for any possible performance optimizations for the VM. I've attached my final Vagrantfile and pasted my most relevant environment information below. I continued to run the permissions monitoring script I pasted in discussion opening as well.
