RHBA-2009:1092 - xen bug fix update

Synopsis

xen bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated xen packages that resolve an issue 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:

  • the Linux bonding driver aggregates multiple network interfaces into a single, local "bonded" interface. The 802.1Q specification (also known as VLAN tagging) allows multiple bridged networks to transparently share a single physical network link. When attempting to use a bonded interface and 802.1Q VLAN tagging together, the "network-bridge-bonding" networking script incorrectly called the ifdown command on interfaces other than "bond0", with the result that only the bond0 bridge became active (and not, for example, the "bond0.5" bridge). With these updated packages, using interface bonding together with 802.1Q VLAN tagging works as expected and all interfaces that are expected to become active do so, thus resolving the issue.

All users of the xen packages are advised to upgrade to these updated packages, which resolve this issue.
