Hello, thank you for fast response.
The point of changing the max_mem_size is little tricky, as we have
environments with together ~13k VMs running on top of ovirt, no kidding
:) and currently doing upgrades from 3.6 > 4.1. So we can easy set those
values to the needed ones for every VM, thats not a big deal.
However, I was just hoping it is editable without changing/modifying our
current API calls, for any newly created VM (as this is the reason for
asking for help), somewhere in engine-config or in DB.
I'll just opened an RFE https://bugzilla.redhat.com/show_bug.cgi?id=1475382
Best regards,
Ladislav Humenik

if the issue is with GUI then setting the max memory in the template
would be inherited to all VMs from that template, you can even change
that in “Blank” I think, Jakube?
That’s for the default case, you can change that any way you like for
the concrete VM you’re creating.
if the issue is with API you can simply provide any number for the max
mem in all the requests
the VM[64|32]BitMaxMemorySizeInMB values are for the total maximum the
particular qemu we ship supports, it’s not anything you should need to
change.
