I'm using Linux 2.6.32.2 with qemu-kvm-0.12.1.1 and, testing memory ballooning, I obtained the following message: root@ubuntu:~# telnet localhost 5001 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. QEMU 0.12.1 monitor - type 'help' for more information (qemu) (qemu) (qemu) (qemu) info balloon The balloon device has not been activated by the guest I have understood that to do balooning it is sufficient that kernel of guest is compiled with virtio-balloon driver: test:~# uname -a Linux test 2.6.32-dgb #1 SMP Thu Dec 24 23:42:21 ART 2009 x86_64 GNU/Linux test:~# test:~# test:~# test:~# cat /boot/config-2.6.32-dgb | grep -i virtio CONFIG_NET_9P_VIRTIO=3Dm CONFIG_VIRTIO_BLK=3Dm CONFIG_VIRTIO_NET=3Dm # CONFIG_VIRTIO_CONSOLE is not set CONFIG_HW_RANDOM_VIRTIO=3Dm CONFIG_VIRTIO=3Dm CONFIG_VIRTIO_RING=3Dm CONFIG_VIRTIO_PCI=3Dm CONFIG_VIRTIO_BALLOON=3Dm Which can be the problem?
