"The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in
the RHSA-2018:0369 advisory.

    OpenStack Compute (nova) launches and schedules large networks of virtual machines, creating a redundant
    and scalable cloud computing platform. Compute provides the software, control panels, and APIs required to
    orchestrate a cloud, including running virtual machine instances and controlling access through users and
    projects.

    python-novaclient is the python client for the OpenStack Nova API. The client's Python API (the novaclient
    module) and command-line script (nova) both implement 100% of the OpenStack Nova API.

    The following packages have been upgraded to a later upstream version: openstack-nova (14.1.0), python-
    novaclient (6.0.2). (BZ#1501736)

    Security Fix(es):

    * By rebuilding an instance using a new image, an authenticated user may be able to circumvent the Filter
    Scheduler, bypassing imposed filters (for example, the ImagePropertiesFilter or the IsolatedHostsFilter).
    (CVE-2017-16239)

    Red Hat would like to thank the OpenStack project for reporting this issue. Upstream acknowledges George
    Shuklin (Servers.com) as the original reporter.

    Bug Fix(es):

    * Prior to this update, QEMU (also known as TCG) guests had an issue where the `guest.get_vcpu_info`
    method was throwing an exception indicating that 0 were vCPUs used on the host, regardless of how many
    guests were running. Consequently, this caused the 'get_available_resources' method to report incorrect
    vCPUs used values for the Compute node. This meant it was overcounting resource consumption for plain QEMU
    guests, as they can only ever consume 1 pCPU of time, regardless of vCPU count. With this update, if a
    host does not report detailed vCPU usage from libvirt, then it should default to reporting 1 vCPU per
    guest, so that the 'vcpus_used' field reports some reasonably meaningful data on host CPU usage. As a
    result, libvirt does not report that 'cpu affinity is not supported' when guests are running in TCG.
    (BZ#1515165)

    * With this enhancement, the act of evacuating instances with pinned CPUs can result in these instances
    being hosted on a hypervisor which already handles instances with the same pinning configuration. This was
    added because the resource tracker does not track CPU pinning for instances on hosts. As a result, a
    condition has been added to the NUMATopologyFilter filter, which passes on hosts which already manage an
    instance with same CPU pinning configuration as the instance being evacuated. (BZ#1517272)

    * Previously, the `request_spec.spec` column's TEXT type was too small, with the result that large
    request_specs may not have fit successfully. Consequently, running the online data migration as part of an
    OSP9 to OSP10 upgrade could have resulted in failure if an instance created before the upgrade had a large
    request_spec (for example, by having many members in its affinity/anti-affinity group). With this update,
    the request_spec.spec column has been increased to `MEDIUMTEXT`. As a result, online data migration should
    no longer fail during a OSP9 to OSP10 upgrade. (BZ#1526082)

    * Previously, when detaching a Ceph volume connected to guest as a PCI device, the volume was not detached
    and libvirt reported an invalid PCI address. This arose because the PCI address of the device was not
    properly formatted due to a missing method in the guest XML formatter. To address this issue, this update
    adds a proper `format_dom` method for `LibvirtConfigGuestDeviceAddressPCI`. As a result, it is now
    possible to detach a Ceph volume. (BZ#1527345)
