[ovirt-users] Balloon driver unavailable

[Groten, Ryan]

I also recently started getting these errors.  They started when I upgraded from 3.4.0 to 3.4.2.
The error appears on certain VMs (but not all) consistently every 15 minutes.  It doesn't matter if the "Memory Balloon Device Enabled" checkbox checked or unchecked.

I got the message to stop appearing by changing the value of Physical Memory Guaranteed to match the VMs configured memory.

Just an FYI.

In my case the balloon driver was installed and it was running. The problem was eventually resolved by uninstalling the entire agent suite, rebooting and reinstalling it. Doing the same just for the balloon driver didn't work.

I'm seeing it for a VM that most definitely does have the balloon driver installed. Care to take another guess?

you receive this error because on your cluster configurations you have checked "Enable Memory Balloon Optimization", and on some of your VMs there aren't balloon driver available; if you don't want anymore this warning messages you can uncheck this under

Clusters -> (select your cluster) edit -> Optimization -> uncheck Enable Memory Balloon Optimization
