Comment 2 for bug 902951

Chuck,
  As shown below, at very least the current pangolin -virtual kernel *does* have VIRTIO_BLK=y, but the -server kernel does not.
  This *is* a change from oneiric, where both -server and -virtual of 3.0.0-14 have VIRTIO_BLK and VIRTIO_NET built in.
  So, I would say that unless there is a reason for this change in behavior, we should have these options built in.

$ grep VIRTIO /boot/config-3.2.0-4-virtual
CONFIG_NET_9P_VIRTIO=m
CONFIG_VIRTIO_BLK=y
CONFIG_VIRTIO_NET=y
CONFIG_VIRTIO_CONSOLE=m
CONFIG_HW_RANDOM_VIRTIO=m
CONFIG_VIRTIO=y
CONFIG_VIRTIO_RING=y
CONFIG_VIRTIO_PCI=y
CONFIG_VIRTIO_BALLOON=m
CONFIG_VIRTIO_MMIO=m

$ grep VIRTIO /boot/config-3.0.0-14-server
CONFIG_NET_9P_VIRTIO=m
CONFIG_VIRTIO_BLK=y
CONFIG_VIRTIO_NET=y
CONFIG_VIRTIO_CONSOLE=m
CONFIG_HW_RANDOM_VIRTIO=m
CONFIG_VIRTIO=y
CONFIG_VIRTIO_RING=y
CONFIG_VIRTIO_PCI=y
CONFIG_VIRTIO_BALLOON=m
