In EL 8 , there is no 'default' python. You can use both. My choice would be ansible because APIs change , but also ansible modules are updated. If you create your own script , you will have to take care about the updates, while with ansible - you just update the relevan packages :) Best Regards, Strahil Nikolov В сряда, 30 септември 2020 г., 22:55:40 Гринуич+3, Jeremey Wise <jeremey.wise@gmail.com> написа: As the three servers are Centos8 minimal installs. + oVirt HCI wizard to keep them lean and mean... a couple questions 1) which version of python would I need for this (note in script about python 2 but isn't that deprecated?)

If this is added to rc.local. Of the two nodes hosting HA for oVirt-engine.. node which boots first will host (or so it seems). I think if I add this to both those hosts .. it will not create issues. Any thoughts? On Wed, Sep 30, 2020 at 3:23 PM Derek Atkins <derek@ihtfp.com> wrote:

The script is smart enough to wait for the engine to be fully active.

i would like to eventually go ansible route.. and was starting down that path.... but this is fabulous.
I will modify and post how it went.
One question: How /where do you set this saved new and delicious script so once oVirt-engine comes up... it runs?
Thanks

Hi,
I had a script based around ovirt-shell which I re-wrote as a script around the Python SDK4 which I run on my engine during the startup sequence. The script will wait for the engine to come up and ensure the storage domains are up before it tries to start the VMs. Then it will go ahead and start the VMs in the specified order with specified delay and/or wait-for-up signal between them.
You can find my scripts at https://www.ihtfp.org/ovirt/
Or you can go the ansible route :)
Enjoy!

When I have to shut down cluster... ups runs out etc.. I need a sequence set of just a small number of VMs to "autostart"
Normally I just use DNS FQND to connect to oVirt engine but as two of my VMs are a DNS HA cluster.. as well as NTP / SMTP /DHCP etc... I need those two infrastructure VMs to be auto boot.
I looked at HA settings for those VMs but it seems to be watching for pause /resume.. but it does not imply or state auto start on clean first boot.
Options?
