Hi, I believe we do not support this, but there is something similar in the VDSM configuration (/etc/vdsm/vdsm.conf). There are two options: host_mem_reserve and extra_mem_reserve that allow you to reserve memory for the OS and your application. You should be aware of features like fencing though. oVirt can decide to reboot the host and that is probably not what you want when a custom application is running there as well. Is there any reason why the application cannot be run inside a VM? Best regards -- Martin Sivak SLA / oVirt On Thu, Dec 22, 2016 at 4:19 PM, shishir praksh <shishirprakash@live.com> wrote:
