Can you try with the firewall disabled on both the host and the guests? If it works, then we know it's a firewall issue. You probably need to allow traffic through 1229/udp on the host, in addition to 1229/tcp on the guests, if you are not already doing so. (Not sure if 1229/tcp is needed on the host.) You can also try with SELinux (or AppArmor or whatever) disabled or not-enforcing. I haven't configured or troubleshot fence_xvm or fence_virt in a long time. Firewall issues have been the most common problem for me though. -- Regards, Reid Wahl (He/Him) Senior Software Engineer, Red Hat RHEL High Availability - Pacemaker _______________________________________________ Manage your subscription: https://lists.clusterlabs.org/mailman/listinfo/users ClusterLabs home: https://www.clusterlabs.org/
