Hi oVirt,
What is the cleanest way to increase the memory and cpu for SHE engine?
Did you try to simply edit the vm from the admin ui? This should be
possible for most fields for quite some time now:
https://bugzilla.redhat.com/show_bug.cgi?id=1160094
We have the Engine running on top of three HA hosts, so I guess the specs need to be
change on all three, while engine is down.
Is it done by editing the VM libvirt conf file or some other way?
Where do I allocate more RAM to JAVA for oVirt?
You can control the values passed as -Xms and -Xmx using the config
values ENGINE_HEAP_MIN and ENGINE_HEAP_MAX.
They are set by engine-setup on initial setup but not changed later.
It writes /etc/ovirt-engine/engine.conf.d/10-setup-java.conf .
It's probably safer to create your own file for overriding, e.g.
99-my-setup-java.conf or something.
There have been various relevant changes to this over the years, you
can search bugzilla for 'ENGINE_HEAP_MIN' to find them.
We are currently running 4.3.8 version.
Kindly awaiting your reply.
Good luck and best regards,
