Change default "Physical Memory Guaranteed" value
Yo! Is there a way to easily change this value? I have checked engine-config, files under "/etc/ovirt-engine/config" and "/usr/share/ovirt-engine/conf" and couldn´t find anything after a quick glanse. I just want to lower it from 1024 MB to 512. TIA /K

FWIW, I created a NIC- and Disk-less Template with the settings I wanted and pointed to that template in my "Small" Foreman "Compute profile", so that I could create a VM in oVirt from Foreman with 512 MB RAM. /K PS. CentOS 7 won´t even pxe-boot with any less than 1536 MB any way :(

You can consider using the CentOS cloud image. It is available from the oVirt image repository and AFAIR can boot in VMs with as little as 500MB of RAM. I think its just the installer that needs that much RAM, if you boot from pre-installed images you can do with much less (And you can also save on disk space and I/O by using thin clones). -- Barak Korren RHV DevOps team , RHCE, RHCi Red Hat EMEA redhat.com | TRIED.

Of course, once the VM is installed, I can go in and change the RAM to 512 MB and it´ll boot just fine. It´s as you say that it´s just the installer that absolutely needs it.

That is also an option but I just don´t want to have a dozen images to update and maintain, I´m lazy:) /K

Most of the defaults are coming from the Blank template. You can edit it, just beware that changes are global
