Hi, I want to use 384 GB RAM with 40 Core CPU in my compute node...i want to know how i can assign the overhead memory to Qemu/KVM for the host machine purpose,so it will be well optimize and stable.. Thanks, Punit

afaik ovirt does reserve some portions of memory for itself, so there's nothing to do imho. -- Mit freundlichen Grüßen / Regards Sven Kieske Systemadministrator Mittwald CM Service GmbH & Co.

Hi Sven, Thanks...is there any guide or link for the optimization of the ovirt host for best performance and stability ?? Thanks, Punit On Fri, Oct 31, 2014 at 4:48 PM, Sven Kieske <s.kieske@mittwald.de> wrote:

Thanks, Punit
I don't remember any particular doc regarding it, it could be nice to have something related to it added to the great doc we now have on oVirt: http://www.ovirt.org/OVirt_Administration_Guide oVirt already runs some optimizations/configurations by itself, but if your hosts are based on CentOS/Red Hat 6.x I think you could also refer to these docs https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/htm... https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/htm... and put questions and write answers here, if you find something useful not already covered in oVirt semi-automatic setup Gianluca
