Nova requires python-libguestfs in Kilo

[Kevin Carter]

For Nova in Kilo as of "2015.1.dev672" the system package "python-guestfs" which brings in "libguestfs0" is required. While we may be able to get around requiring in later releases, as this looks like it may be an issue with the dev release of Nova for Kilo, it did not function in fallback mode at all. Without that package installed this was the error:

    Updated repository for minimum viable kilo install

    * Updated Keystone wsgi and paste files from upstream.
    * Updated all clients in the openstack_client.yml file.
    * Kilo services are tracking the head of master.
    * Removed pinned middleware because they're pinned else where.
    * Added additional service references for neutron vpnaas, fwaas, and
      lbaas which have now been moved into their own repos and no longer
      exist within the core neutron repository.
    * The neutron vpnaas, fwaas, and lbaas have been removed from the
      basic plugins being loaded and a comment has been added to describe
      how one might add them back in.
    * Updated rootwrap filters for neutron dhcp and l3.
    * Updated heat policy.json
    * Added the `python-libguestfs` to the nova-compute installation
      packages.
    * Updates all services to point to the latest kilo tag

    Services updated due to deprecated configs:
    * Keystone
    * Glance
    * Nova
    * Neutron (is still using the deprecated nova auth plugin)
    * Heat
    * Tempest

    Items for future work post initial release:

      TODO(cloudnull) remove this script once the bug is fixed.
    * roles/rabbitmq_server/tasks/rabbitmq_cluster_join.yml:17:
      TODO(someone): implement a more robust way of checking

Hi,
 I am facing the same issue. which package I need to install to correct this issue?

[Kevin Carter (kevin-carter)]

@randhirsingh21 i was able to resolve this issue by installing "python-guestfs".

[randhir singh (randhirsingh21)]

Thanks Kevin, I have installed python-libguestfs, libguestfs-tools and it working.

[Davanum Srinivas (DIMS) (dims-v)]

This issue was fixed in the openstack/nova 14.0.0.0b1 development milestone.
