RHBA-2009:1514 - Bug Fix Advisory

Topic

Updated xen packages that close a memory leak in xend are now available.

Description

Xen is a high performance and secure open source virtualization framework.
Virtualization allows users to run guest operating systems in virtual
machines on top of a host operating system.

These updated xen packages fix the following bug:

• issuing an "xm info" command or any virsh commands caused xend to leak

memory. As well, xend's memory consumption grew very quickly in combination
with cluster suite, which uses virsh to monitor running guests. This update
fixes the underlying errors in the PyList_Append and PyDict_SetItemString
functions that caused the memory leaks. (BZ#528163)

All xen users are advised to upgrade to these updated packages, which
resolve this issue. Note: after installation, the xend service must be
restarted for this update to take effect.
