RHBA-2011:1566 - Bug Fix Advisory

Topic

Updated fence-virt packages that fix two bugs and add one enhancement 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:

• Prior to this update, the domain parameter was missing from the metadata. As a

consequence, existing configurations utilizing the domain parameter did not
function correctly when fencing. This update adds the domain parameter for
compatibility. Now, existing configurations work as expected. (BZ#719645)

• Prior to this update, hash mismatches falsely returned successes for fencing.

As a consequence, data corruption could occur in live-hang scenarios. This
update corrects the hash handling of mismatches. Now, no more false successes
are returned and the data integrity is preserved. (BZ#720767)

This update also adds the following enhancement:

• With this update, the libvirt-qpid plugin now operates using QMF version 2.

(BZ#691200)

All users of fence-virt are advised to upgrade to these updated packages, which
fix these bugs and add this enhancement.
