I was feeling good about recovering my installation so I decided to go for 4.2.
I believe the update went well and saw the DB get updated (I did register the xen template before doing the update). However I am not able to "see" the login prompt of the UI. I have tried various browsers (chrome, firefox, IE) and the page loads but it is all blank so I can't log in to see what is happening. Also, I am on Ubuntu so the cloudstack-sysvmadm script does not work. I am now stuck unable to restart the system vms. Can I just kill them in XenCenter and wait for Cloudstack to see them gone so that it restarts them? Anyone successful at upgrading management server on Ubuntu with Xen hosts? thanks, Carlos
