[ovirt-users] SLA : RAM scheduling

[Gilad Chaplik]

Hi Nathanaël, 

You have 2 ways to get what you're after (quick/slow):
1) install 'oVirt's external scheduling proxy', and write an extremely simple weight function that orders hosts by used memory, then add that to your cluster policy.
2) open an RFE for oVirt 3.4 to have that in (https://bugzilla.redhat.com/enter_bug.cgi?product=oVirt).

let me know if you consider (1), and I'll assist.

anyway I suggest you'll open an RFE for 3.5.

Thanks, 
Gilad.
