RHBA-2014:1589 - Bug Fix Advisory

Topic

Updated fence-virt packages that fix two bugs and add two enhancements are now
available for Red Hat Enterprise Linux 6.

Description

The fence-virt packages provide a fencing agent for virtual machines as well as
a host agent, which processes fencing requests.

This update fixes the following bugs:

• Previously, the manual page for the fence_virt.conf file did not describe

the relationship between socket path for fence_virtd and virtual machine serial
socket path. This could cause confusions or misunderstandings. With this update,
the description of "path" in the manual page has been extended to explain the
aforementioned difference. (BZ#1014238)

• Prior to this update, the fence-virt agent could not fence inactive virtual

machines. As a consequence, the cluster became unresponsive because the
fence_virtd daemon was unable to find the running domain. The underlying source
code has been patched, and fence-virt now fences both active and inactive
virtual machines. (BZ#1104740)

In addition, this update adds the following enhancements:

• With this update, the libvirt backend of the fence_virt daemon has

been extended to support multiple KVM hypervisors. (BZ#914144)

• With this update, fence-virt fencing using KVM serial ports instead of

network multicast is supported for production use. (BZ#1054225)

Users of fence-virt are advised to upgrade to these updated packages, which fix
these bugs and add these enhancements.
