8.56. fence-virt

Updated fence-virt packages that fix two bugs and add two enhancements are now available for Red Hat Enterprise Linux 6.
The fence-virt packages provide a fencing agent for virtual machines as well as a host agent, which processes fencing requests.

Bug Fixes

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.
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.
In addition, this update adds the following


With this update, the libvirt backend of the fence_virt daemon has been extended to support multiple KVM hypervisors.
With this update, fence-virt fencing using KVM serial ports instead of network multicast is supported for production use.
Users of fence-virt are advised to upgrade to these updated packages, which fix these bugs and add these enhancements.
