[ovirt-users] Hosted Engine increase memory

[Artyom Lukianov]

I believe it depends on the version of Ovirt that you use, the Yanir
solution can be relevant only for the 3.5 version. Started from version 3.6
you can edit HE VM memory via UI without any troubles, the only thing that
you must be aware of under 4.1 you will need to wait for some time, until
the engine update HE VM OVF file(in 4.2 you do not need to wait).

   1. Enable global maintenance
   2. To reduce wait time you can change # engine-config
   OvfUpdateIntervalInMinutes=1 && systemctl restart ovirt-engine
   3. Change HE VM memory via UI and wait for 1-2 minutes
   4. Change OvfUpdateIntervalInMinutes parameter to default value
   5. Restart HE VM # hosted-engine --vm-poweroff && hosted-engine
   --vm-start
   6. Disable global maintenance

In 4.2 you do not need to apply steps 2-4

Best Regards
