Description of problem: According to https://bugzilla.redhat.com/show_bug.cgi?id=1824472#c1 Ballooning should be enabled by default on Default cluster. Currently, Ballooning is enabled by default on Default cluster but not on new clusters created: engine=# select enable_balloon,bios_type from cluster where name='Default'; enable_balloon | bios_type ----------------+----------- t | 2 engine=# select enable_balloon,bios_type from cluster where name='new_cluster'; enable_balloon | bios_type ----------------+----------- f | 2 Version-Release number of selected component (if applicable): ovirt-engine-4.4.0-0.33.master.el8ev vdsm-4.40.13-1.el8ev.x86_64 How reproducible: 100% Steps to Reproduce: 1. Create new cluster and add host to cluster. 2. 3. Actual results: Ballooning is disabled. Expected results: Ballooning behavior should be the same as in Default cluster (enabled). Additional info:
Is there any reason why ballooning is not enabled in new clusters?
other than it being a bug? no
Verification on ovirt-engine-4.4.1.7-0.3.el8ev.noarch. The new cluster is created now with 'Enable Memory Balloon Optimization' = true, 'Enable KSM' = false. While the Default cluster is set with both these options true. Please confirm if this result is what we wanted to get engine=# select name, enable_ksm from cluster_view; name | enable_ksm ---------------------------+------------ Default | t new_cluster | f engine=# select name, enable_balloon from cluster; name | enable_balloon ---------------------------+---------------- Default | t new_cluster | t
I didn't change the behaviour for enable_ksm. I'm not sure it is in the scope of this bug. Arik, should it be changed also?

after discussion with Arik this one I verify. for ksm I create a separate bug
