Hi, Most of our VMs are SLES SP15 and also few are CentOS 7. But the problem looks to be same for any type of VM. Today, I tried to clear the "buff/cache" memory manually for one of the VM using "sync; echo 3 > /proc/sys/vm/drop_caches" linux command and then I noticed in ovirt GUI that VM's memory usage dropped to 54% from 98%. So, it is clear that ovirt is not considering the actual "available" memory but is considering "free" + "buff/cache" and is reporting the same in ovirt GUI as memory usage %. Isn't this a bug? /Kishore
