[ovirt-users] howto change hosted-engine config memory

Tue Feb 2 19:33:15 UTC 2016

Hi Simone,

I have exactly as you stated, but found maybe a problem/bug.

1. I put hosted engine to maintenance and powered it off
2. Changed memory in /etc/ovirt-hosted-engine/vm.conf to memSize=8192
3. I restarted both ovirt-ha-agent and ovirt-ha-broker:
/etc/init.d/ovirt-ha-broker
restart && /etc/init.d/ovirt-ha-agent restart
4. I started hosted-engine and turned off global maintenance.

The hostedengine webinterface still says 4096MB

Now I logged on with ssh and ran the command "free -m"
This command shows:

Mem:          7870       ...
So, I believe my hostedengine was updated, but the webinterface is showing
incorrect values: http://screencast.com/t/Bg5xU0Ja

Any idea why web interface is not showing correct value under Defined or
Physical memory?

Regards,
Paul
