RHBA-2014:1513 - Bug Fix Advisory

Topic

Updated virt-who package that fixes several bugs and adds various enhancements
is now available for Red Hat Enterprise Linux 6.

Description

The virt-who package provides an agent that collects information about virtual
guests present in the system and reports them to the Red Hat Subscription
Manager tool.

The virt-who package has been upgraded to upstream version 0.10, which provides
a number of bug fixes and enhancements over the previous version. This update
includes support for multiple vCenter servers, fixed querying by cluster in
large ESX environments, corrected communication with Red Hat Satellite server
when ESXi has no host, fixed unregistering from Subscription Asset Manager (SAM)
server, fixed bug in Virtual Desktop and Server Management (VDSM) mode, support
for encrypted credentials, and fixed error when creating new VMs. (BZ#1002640,
BZ#994575, BZ#1002447, BZ#1009230, BZ#1011877, BZ#1017056, BZ#1081286,
BZ#1082416)

This update also fixes the following bugs:

• Previously, the virt-who daemon did not report guest attributes to the server,

which disabled the virt_guest_limit feature. With this update, virt-who has been
modified to correctly report guest attributes. As a result, virt_guest_limit is
now supported by virt-who. (BZ#1098019)

• Prior to this update, every call to Libvirtd.listDomains() function from the

/usr/share/virt-who/virt/libvirtd/libvirtd.py script opened a new connection to
the libvirtd daemon but did not close it. Consequently, after several
iterations, virt-who consumed all connections allowed for any client of
libvirtd. With this update, Libvirtd.listDomains() has been modified to properly
close the livirtd connections, thus fixing this bug. (BZ#1113938)

Users of virt-who are advised to upgrade to this updated package, which fixes
these bugs and add these enhancements.
