Could you explain how you measure that exactly?
I check the resident memory (RES) of qemu-system-x86_64 proces.
Yes, this should not happen. One interesting thing to try would be switching device type from virtio-net to e1000. This means vhost will be initialized but not started.
So with virtio-net-pci + vhost=on I have VM process on 580-590 MB of RES memory, if I disable vhost OR set e1000 NIC and leave vhost enabled, its take just 109-120 MB of resident memory.
The memory usage check is done after few minutes after VM start, and the vm have minimal debian7 system without even single additional service.
