Description Doran Moppert 2019-06-03 07:19:34 UTC 
It was discovered that in fence-agents prior to 4.3.4, including non-ASCII characters in a guest VM's comment or other fields would cause fence_rhevm to exit with an exception.  In cluster environments, this could lead to preventing automated recovery or otherwise denying service to clusters of which that VM is a member.
