RHBA-2011:1692 - Bug Fix Advisory

Topic

An updated virt-top package that fixes three bugs and adds one enhancement is
now available for Red Hat Enterprise Linux 6.

Description

The virt-top utility displays statistics of virtualized domains and uses many of
the same keys and command line options as the top utility.

This update fixes the following bugs:

• The CSV output of virt-top contains only the headers for the first virtual

machine. This update adds a processcsv.py script to virt-top so that the CSV
output can now be split up into multiple files, each file containing full
headers. (RHBZ#665817)

• When a libvirt error happens early during virt-top start-up, an obscure error

message can be printed. With this update, the manual page contains added
instructions for debugging libvirt errors that can occur during program
initialization. (RHBZ#680031).

• Prior to this update, the terminal was not properly restored if the --csv flag

was given. This update modifies the code so that the terminal is now restored
in the correct mode. (BZ#730208)

This update also adds the following enhancement:

• With this update, the domain memory information is now displayed in the CSV

output mode. (RHBZ#680027)

All virt-top users are advised to upgrade to this updated package, which fixes
these bugs and adds this enhancement.
