Hi,
no, not really, it’s just a UI-side default suggestion.
In API you supply it yourself in the request, any value you would want. It just 
limits the max hotpluggable amount of memory

Thanks,

Re: [ovirt-users] Feature: Maximum memory size | BUG

2017-07-27 Thread Ladislav Humenik


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.


Thanks,
michal

[ovirt-users] Feature: Maximum memory size | BUG

Hallo, after engine update to 4.1.2 from 4.0.6 we have following bug
