QEMU device virtio-balloon allows memory ballooning which is useful for memory constrained environment.

I think it should be nice to add an option for memory ballooning. In QEMU, adding -device virtio-balloon enables memory ballooning.

How does one use the balloon? I can enable it and the guest sees the PCI device but it doesn't seem to do anything?

I've tried adding -m size=1G,maxmem=8G but it doesn't grow past 1G.
