It was mentioned that VSZ accounts for virtual memory, not used physical RAM. It's not a guaranteed way of identifying excessive RAM usage. Please post /proc/$PID/maps so we can confirm the 900 MB overhead is heap, not just mmaped files or other things. Also please post the full qemu-kvm command-line so it's clear which features are in use. Stefan
