RHBA-2013:0391 - Bug Fix Advisory

Topic

Updated virt-top packages that fix two bugs and add three enhancements are 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:

• Prior to this update, the "-o" (sort) option was not properly described in the

output of the "virt-top --help" command. Four of the possible sort parameters
were not mentioned in the description. This bug has been fixed and the full
range of sort parameters is now shown in the virt-top --help message.
(BZ#807176)

• Previously, the column names of the virt-top summary table were not explained

in the virt-top man page. The manual page has been updated, and the headings are
now properly documented in the "COLUMN HEADINGS" section. (BZ#834208)

This update also adds the following enhancements:

• The copyright information has been updated in the virt-top man pages and help

documents. (BZ#825627)

• This update adds a separate man page for the processcsv.py script, which was

previously documented only in the virt-top man page. (BZ#835547)

• With this update, the "virt-top -1" command has been enhanced to separately

display the usage of virtual CPUs. Two numbers are now shown under each domain
column; the first is the percentage of the physical CPU used by the domain and
the hypervisor together, the second is the percentage used just by the domain.
This information is important for performance tuning and other tasks.
(BZ#841759)

All users of virt-top are advised to upgrade to these updated packages, which
fix these bugs and add these enhancements.
