All,
I put together a full purge ansible script for CentOS. I figured I'd
share it here. I ran into many issues with spurious failures of
installs when I would try to reinstall ovirt on CentOS after having
"removed" it.
I was developing an automated install of our own software along with
ovirt but along the way I had to reinstall on the same box numerous
times. Initially I'd get spurious failures from leftover cruft that
would get in the way. I eventually found
this:https://www.ovirt.org/documentation/how-to/hosted-engine/#recoving-f...
and then crafted my own ansible purge script.
It uses ovirts own engine cleanup script first if it exists, then
fully cleans every other thing that can affect it.
Tested on CentOS, probably will work on other distros without too much
trouble. Hopefully someone saves themselves some grief

#The reason we include the ovirt packages is so that they can be reinstall
