[Bug 1411278] Re: nova-compute doesn't reconnect to libvirtd

OK so I'm pretty sure that newer nova-compute versions do reconnect to
libvirt if connections are lost (I just checked on a newton cloud,
restarting libvirt did not cause any side-effects in nova, and the
compute unit is still reporting as active and is functional).

This is possibly an issue that impacted older nova versions; either way
this is not a charm problem, so adding a task for nova in Ubuntu
(icehouse is no longer supported upstream).

Title:
  nova-compute doesn't reconnect to libvirtd

Status in nova package in Ubuntu:
  New
Status in nova-compute package in Juju Charms Collection:
  Invalid

Bug description:
  I've found nova-compute disabled on a prod system with this in the
  log:

  2015-01-09 20:14:53.906 26500 WARNING nova.virt.libvirt.driver [-]
  Connection to libvirt lost: 1

  And this in libvirt.log:

  2015-01-09 20:14:53.647+0000: 6646: error : netcfStateCleanup:109 :
  internal error: Attempt to close netcf state driver with open
  connections

  However, libvirtd seems to operate normally now. After restarting
  nova-compute it connected successfully to libvirtd.

  Shouldn't nova-compute try reconnect automatically?
