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

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:)

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).

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.

[ovirt-users] Change default "Physical Memory Guaranteed" value

2017-04-26 Thread Karli Sjöberg 
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
