[Bug 1048973] Re: udev does not export virtioserial ports in /dev

[Neil Wilson]

virtio_console (which is the module that does the magic) doesn't appear
to be in the loadable modules list and since it doesn't load I'm
presuming it isn't in the kernel build list either.

Adding the kernel to the packages affected.

Title:
  udev does not export virtioserial ports in /dev

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

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.
