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.

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?

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?) [root@thor /]# yum install python Last metadata expiration check: 2:29:38 ago on Wed 30 Sep 2020 01:18:32 PM EDT. No match for argument: python There are following alternatives for "python": python2, python36, python38 Error: Unable to find a match: python

2) When you have three nodes.. one is set to host the ovirt-engine active, and another as backup. 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?

<smacks forehead> Ya.. that is a lot easier. Someone should put this in as a feature request. I don't want HA (and have errors on getting that to work) I just want VMs to boot on initial cluster start. this was standard in libvirt :) I am trying to convert to oVirt ways...

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! -derek On Wed, September 30, 2020 11:21 am, Jeremey Wise wrote: > 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? > > > -- > p <jeremey.wise(a)gmail.com&gt;enguinpages > _______________________________________________ > Users mailing list -- users(a)ovirt.org > To unsubscribe send an email to users-leave(a)ovirt.org > Privacy Statement: https://www.ovirt.org/privacy-policy.html > oVirt Code of Conduct: > https://www.ovirt.org/community/about/community-guidelines/ > List Archives: > https://lists.ovirt.org/archives/list/users@ovirt.org/message/VAYHFFSANCB... > --        Derek Atkins                 617-623-3745        derek(a)ihtfp.com            www.ihtfp.com        Computer and Internet Security Consultant
