RHBA-2013:0798 - Bug Fix Advisory

Topic

An updated openstack-nova package that fixes several bugs is now available for
Red Hat OpenStack 2.1 (Folsom).

Description

OpenStack Compute (Nova) is open source software designed to
provision and manage large networks of virtual machines, creating a
redundant and scalable cloud computing platform. It provides the
software, control panels, and APIs required to orchestrate a cloud,
including running instances, managing networks, and controlling access
through users and projects.

These updated packages include an update to the latest stable release of
OpenStack Folsom, version 2012.2.4. These packages address the following issues:

• Previous releases of openstack-nova would produce a stack trace that would get

sent back to the client, and consequently displayed to the user, when attempting
to migrate a virtual machine to an invalid host. Now, a more descriptive error
message is displayed to the user. (BZ#927167)

• Previous releases disabled APIC support in guests. As a result, certain guest

operating system images would not operate correctly. Now, Nova enables APIC
support by default in instances, which resolves the issue. (BZ#921517)

• Previous releases of Nova did not support the 'network-create' command. When

an administrator issued this command from the Nova client, the command would
fail and a stack trace would be produced. This has been resolved. (BZ#948938)

• Prior to this update, the /var/log/nova directory was world-readable. With

this update, world read permissions have been removed from the directory.
(BZ#956818)

• If an administrator typed in the wrong netmask size (for example /2 instead of

/24), nova-manage would try to allocate 2^31 floating IPs, potentially causing a
machine to run out of memory. Nova-manage no longer allows sizes over 1 million
floating IP addresses, which resolves the issue (BZ#918761)

• The resume_guests_state_on_host_boot option in /etc/nova/nova.conf

incorrectly implied that the default was value 'True', when it is, in fact,
'False'. (BZ#923086)

• Previous releases of Nova would fail to restart if a virtual machine had a

CD-ROM device and had also not previously been started by Nova. (BZ#950323)

• Previous releases of openstack-nova would produce a stack trace that would get

sent back to the client, and consequently displayed to the user when running
'nova get-vnc-console' to an instance in the 'BUILD' state. Now, a more
descriptive error message is displayed to the user. (BZ#919868)

All users of Red Hat OpenStack 2.1 (Folsom) are advised to install these updated
packages.
