On the PowerPC platform, binary files generated by the OCaml compiler were running with executable stacks. As this was not a necessary or desirable behavior, Exec-Shield stack protection has been enabled for the file usr/bin/virt-top. Binary files generated by the OCaml compiler no longer run with executable stacks. (BZ#605124)

The "historical %CPU" was displayed at the bottom of virt-top's output, whereas the virt-top(1) manual page indicated that it was placed at the top of virt-top's display. This update corrects virt-top's output so that the "historical %CPU" is now correctly displayed in the top right-hand corner of virt-top's output, thus resolving the issue. (BZ#629500)

When a user randomly changed the size of the terminal window in which the virt-top utility was running, virt-top aborted unexpectedly. This update corrects the behavior so that virt-top no longer aborts unexpectedly when resizing the terminal window. (BZ#634435)

Previously, the virt-top manual page referenced the xm and xentop utilities of Xen. Because Red Hat no longer ships these utilities with Red Hat Enterprise Linux 6, the references in the virt-top manual page have been removed. The manual page no longer mentions the Xen utilities that are not available in Red Hat Enterprise Linux 6. (BZ#648186)

The virt-top(1) manual page and help option incorrectly indicated that Xen was the default hypervisor. This update corrects the virt-top manual page and help option to remove the incorrect indications. (BZ#676979)

The virt-top utility previously required the ocaml-camomile-data package in order to be built. Because the ocaml-camomile-data package is not present in Red Hat Enterprise Linux 6, and is actually not a requirement for building the virt-top package, this dependency has been dropped. This updated virt-top package no longer requires the ocaml-camomile-data as a dependency. (BZ#661783)

When a user used the "--end-time" option of the virt-top utility, the specified execution time was not followed. Instead, the "--end-time" option gave inaccurate results due to the erroneous computing of timezones. The issue has been resolved by fixing the problem. Now the "--end-time" option works correctly and provides expected output. (BZ#637964)

When using the "--end-time" option of the virt-top utility, the utility did not stop at the time specified. Instead, the utility continued in execution. This has been caused by virt-top not following user's local timezones and making use of UTC instead. The problem has been fixed so that virt-top now uses local timezones and stops at the time specified by the user. (BZ#680344)

Previously, the virt-top(1) manual page did not give correct information on virtual machine's memory usage when running in batch mode. It did not mention the fact that the virt-top utility only shows the memory allocated to the guest, not the real amount of memory used by the guest. This misleading information has been corrected and the virt-top utility manual page no longer confuses the user. (BZ#647991)

Previously, the virt-top's option "-b" as documented in the virt-top manual page did not work as expected. The results of the "virt-top -b" and "virt-top" commands were the same. The issue has been resolved by making virt-top's behavior in batch mode similar to the command "top -b". Now virt-top works correctly in batch mode. (BZ#643893)
