Interesting finding!
BTW, the KVM ballooning requires the host OS to cooperate with the guest OS. If you can modify your kernel so that it does not cooperate with the hypervisor, then the hypervisor can't steal the memory from you.

@yuka@s.umeyashiki.org Try setting kernel cmdline `virtio_balloon.disable=1` or, if you compile your kernel yourself, drop it entirely with `CONFIG_VIRTIO_BALLOON=n`.
