Hi,
I'm looking everywhere for a full list of "OVESETUP" parameters that can be used in the installer answerfile.
Searched the red hat manual and found some in:
"3.6. Passwords in Red Hat Enterprise Virtualization Manager"
But there are more. I can get it from a finished install but some parameters only apply to some types of installation.
I found this one form lzap:
https://gist.github.com/lzap/7a8cbb7f44d41e4ad171
But I don't know if it's complete or just for his personal use.
No hurry, I know you are all busy ;-)
Hi,
The simplest way is to perform setup and record the answer file.
You can even <Ctrl>C at the summary confirmation question and answer file will be generated for you without installing anything.
Full list is available at /usr/share/ovirt-engine/setup/ovirt_engine_setup/, seek *.py and look for @osetupattrs with answerfile=True. Maybe in future we can have utility to extract all with description. Also note:
1. The files there are separated between different packages, so you'll not necessarily have all, if you did not install some optional ones.
2. Not all combinations are supported, and in principle it's possible to manually create answer files that will cause setup to fail, or even to succeed but leave an unsupported, unexpected system setup. I started writing about this some time ago in [1] but got stuck in the middle, and Alon said I should not call it Otopi because it does not document Otopi but engine-setup, and he is largely right. See also [2], which is not directly related (key is not answerfile=True), but does give a relevant example.
[1] http://www.ovirt.org/Otopi [2] https://bugzilla.redhat.com/show_bug.cgi?id=1101001 Yes that was my problem, I was trying to do AIO install but engine-cleanup didn't work because a version mismatch.
So I tried removing everything by hand but the installer never asked me the install local VDSM question... Then I thought I'd get smart and just edit the answer the installer generated and add the AIO lines to it. But nearly all the settings are undocumented so I had to resort to searching on what to set them to on pastebin etc. In the end, I reinstalled the host as it was quicker to do a fresh install. Also I want to create puppet files and deploy engine through foreman. I think as a workaround, I'll do a couple of different installs and rip the generated answer file from them. But when a new parameter get's introduced, I will never know about it until I run into an issue. Something like "ovirt-installer --list-answerfile" should be possible IMHO, as the installer uses and verifies the parameters on install. I'm not a programmer but it should be able to spit out a list them. Kind regards, Jorick Astrego Netbulae
