The VSA package is all you require to deploy a VSA proxy for OpenStack.
The package does need to be installed on an OpenStack instance in the region you are looking to protect.
Another common oversight is not including the port in the keystone URL. Make sure it is formatted like https://keystone-url.domain:443
If all of the above has been done, I would suggest trying to add the OpenStack client again, when it fails to communicate, note the time and check for that time period in the cvd.log file on your VSA proxy. This should provide further details surrounding the failure.
Thank you for your reply, but that wasn't the case.
I reinstalled the vsa proxy on ubuntu 22.04 and it worked.
I think commvault is having problems on ubuntu 24.04, because I'm having problems restoring commvault to an OpenStack environment from a Vm on ubuntu 24.04 but it can't start.
