RHBA-2012:0900 - Bug Fix Advisory

Topic

Updated virt-who packages that fix several bugs and add various enhancement are
now available.

Description

The virt-who package provides an agent that collects information about virtual
guests present in the system and reports them to the subscription manager.

The virt-who package has been upgraded to upstream version 0.6, which provides a
number of bug fixes and enhancements over the previous version. (BZ#790000)

These updated virt-who packages provide fixes for the following bugs:

• When the libvirtd daemon was stopped, the virt-who utility no longer received

information about the state of the guest, and showed an inaccurate list of guest
UUIDs. With this update, polling is used to check the connection to the libvirtd
daemon, and the time for which the list of UUIDs is inaccurate was minimized.
(BZ#746163)

• Prior to this update, the virt-who utility could not connect to the libvirt

daemon due to a regression in the code that handles forking of the virt-who
daemon. With this update, a connection is open to the libvirtd daemon after the
fork of the virt-who daemon; thus, fixing this issue. (BZ#813299)

• This update includes a missing python-suds dependency into the virt-who

specfile. The missing dependency was causing the virt-who daemon to fail to
start. (BZ#801657)

• The virt-who daemon did not use double forking when it was started.

Consequently, the daemon did not detach from the terminal correctly. With this
update, virt-who uses double forking, and is able to correctly detach itself
from the terminal. (BZ#806225)

• Previously, the virt-who utility could not handle all events that were being

sent by the libvirtd daemon. If an unrecognized event was received, virt-who
logged an IndexError in the logs, and returned a traceback error. With this
update, virt-who handles all error events (even unknown), and no longer returns
a traceback error. (BZ#815279)

Users are advised to upgrade to these updated virt-who packages, which resolve
these issues and add these enhancement.
