Subject Re: 4.2.0 Upgrade and System Templates (KVM - Ubuntu 12.04)
Date Sat, 26 Oct 2013 23:22:38 GMT
I'm not sure. Somebody on the list has asked about this before, so you may
be able to find answers in the history. I've never actually done it because
I could never get answers about how it was supposed to work. I did do some
digging and found that cloudstack always looks for the newest system type
template of a certain name and uses that. But I wasn't sure how the script
went about triggering a redeploy of the root disk, it just seemed to reboot
the VMS.

Personally, I've always just replaced the template file by hand, swapping
out the old file with the the new on secondary and primary storage, then
set the global variable that recreates system VMs when you restart them. I
wouldn't recommend doing it that way unless you don't care if it gets
messed up (Dev environment).

When I ran through upgrade scenarios in testing the release, I was always
using the newer template with 4.1 thus didn't need to do that step.
