[ovirt-users] Re: Ovirt engine showing wrong host's memory usage

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"?
