I've observed that oVirt considers cache/buffer memory as "used”.
Where do you see that?
So a host can report, for example, 10% memory utilisation when hosting 0 VMs. A reboot of the host will of course free all that memory and the host will again report something close to 0%.
This caused me a shock a few weeks ago when I thought my cluster was running out of memory.
Given that the kernel will give back the buffer memory as required, is it not perhaps a bit misleading to count it as "used"?
it is not counted as used, https://github.com/oVirt/vdsm/blob/95d734bace00b87a17d333ac1871a489b1812160/...

Hi,
My ovirt engine is showing wrong host's memory usage. Even when this one has no VM. How to fix it ?
What’s wrong with it?
