[Bug 1048973] Re: Quantal kernel doesn't support virtio_console module

[Neil Wilson]

Need to install the 'extra' package which contains the additional
modules.

These dependencies are brought in with the 'linux-image-server' package
but not with the 'linux-image-virtual' package.

Title:
  Quantal kernel doesn't support virtio_console module

Status in “linux” package in Ubuntu:
  Invalid
Status in “udev” package in Ubuntu:
  Invalid

Bug description:
  Under libvirt you can specify special dedicated serial channels that
  link the Host to the Guest OS.

  e.g.

  <channel type='dev'>
    <source path='/dev/urandom'/>
    <target type='virtio'/>
  </channel>

  On a Redhat derivative distribution this would show up in /dev as
  /dev/vport0p1 (with an associated link name if one was specified).

  On Ubuntu they don't appear at all.

  lspci does show that the controller exists:

  
  00:07.0 Communication controller: Red Hat, Inc Virtio console

  
  And the kernel appears to enumerate the device. 

  But no devices are created in the filesystem on Ubuntu.
