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.
