RHBA-2012:0754 - Bug Fix Advisory

Topic

Updated perl-Sys-Virt packages that fix multiple bugs and add various
enhancements are now available for Red Hat Enterprise Linux 6.

Description

The perl-Sys-Virt packages provide application programming interfaces (APIs) to
manage virtual machines from Perl with the libvirt library.

The perl-Sys-Virt package has been upgraded to upstream version 0.9.10, which
provides a number of bug fixes and enhancements over the previous version.
(BZ#752436)

This update also fixes the following bugs:

• Prior to this update, the perl-Sys-Virt spec file did not contain the

"perl(Time::HiRes)" requirement. As a consequence, perl-Sys-Virt could not be
rebuild in mock mode. This update adds the missing requirement to the spec file.
Now, perl-Sys-Virt can is rebuild in mock mode as expected. (BZ#661801)

• Prior to this update, the perl-Sys-Virt man page did not document the "$flags"

parameter for the "get_xml_description" executable. This update modifies the man
page so that the parameter is correctly documented. (BZ#747483)

• Prior to this update, the default settings for the remote domain memory

statistics used a length of 16 bits only. As a consequence, the
get_node_cpu_stats() function could send the libvirt error "code: 1, message:
internal error nparams too large". This update modifies libvirt so that the
maximum length is now 1024 bits. (BZ#748689

• Prior to this update, the bandwidth in the "block_pull and

set_block_job_speed" method was incorrectly given in Kilobytes per second
(Kb/s). This update changes the bandwidth unit to Megabytes per second (Mb/s).
(BZ#773572)

• Prior to this update, the bandwidth for maximum migration bandwidth was

incorrectly given in Kilobytes per second (Kb/s). This update changes the
maximum migration bandwidth unit to Megabytes per second (Mb/s). (BZ#800766)

• Prior to this update, the documentation for "Sys::Virt::StoragePool"

incorrectly stated that the object method "get_info()" returns a hash. This
update corrects this misprint and correctly states that object method returns a
hash reference. (BZ#809906)

In addition, this update adds the following enhancements:

• Prior to this update, the Perl API bindings could not handle tunable

parameters in string format. As a consequence, the block I/O tunable parameters
could not be read or updated. This update adds support for string parameters.
Now, the block I/O tunable parameters can be read and updated from the Perl API.
(BZ#800734)

All users of perl-Sys-Virt are advised to upgrade to these updated packages,
which fix these bugs and add these enhancements.
