TL;DR
If you see either of these errors, check grep 'ERROR' /opt/avi/log/cc_agent_go_{{ cloud }} for the potential cause. In my case, the / character was not correctly processed by Avi's Golang client (facing vCenter).
The Problem
When trying to configure NSX ALB + NSX-T on my home lab, I am presented nothing but the following error:
CC_SE_CREATION_FAILURE
The Process
Avi Vantage appears to be treating this as a retriable error, attempting to deploy a service engine five times, which can be re-executed with a controller restart:
Oddly enough, vCenter doesn't report any OVA deploy attempts. The next thing to check here would be the content library:
Now here's a problem - Avi doesn't provide any documentation on how to troubleshoot this yet - so I did a bit of digging and found that you can bump yourself to root by performing a:
sudo su
Useful note: Avi Vantage is running
bullseye/sid
with only 821 packages listed under dpkg -l | wc -l. They did do a pretty good job with pre-release cleanup, but there are still a few oddball packages in there. I'd give it a 9/10, I'd like to see X11 not be installed but am pleased to see only Python 3!Avi's logs are located in:
/var/lib/avi/log
/opt/avi/log
Here's what I found in alert_notifications_debug.log:

From the looks of things - Avi is talking with NSX-T before vCenter to determine appropriate placement, which makes sense.Update and Root Cause
With the Avi 20.1.6 release, VMware has made a lot of improvements to logging! We're now seeing this error in the GUI (Ensure that "Internal Events" is checked:
/opt/avi/log/cc_

Since we don't get a Redeploy (please VMware!) button, I restarted the controller and all SE deployments succeeded after that.
