Comment 0 for bug 570542

The linux-image-2.6.32-21-virtual kernel package does not include the ahci module:

  $ dpkg-deb -c linux-image-2.6.32-21-virtual_2.6.32-21.32_amd64.deb | grep ahci
  $

this is unfortunately the driver that virtualbox guests need to use virtual sata devices (rather than ide) within virtualbox, meaning that virtualbox guests with the virtual kernel installed won't boot. Installing the ahci.ko from the corresponding linux-image-2.6.32-21-server kernel and updating depmod and the initramfs lets the system boot under virtualbox.

(It doesn't look to be a regression from karmic, as that version's virtual kernel also didn't include the ahci, though I haven't tested it for sure -- it's possible ahci could have been a built-in module).
