Hi In CS 4.2.0 logs running on CentOS 6.4 64 bit, with XenServer 6.0.2 host I can see this:
2013-11-01 07:58:57,114 WARN [xen.resource.CitrixResourceBase] (DirectAgent-124:null) callHostPlugin failed for cmd: network_rules with args seqno: 1, vmIP: 195.238.173.20, deflated: true, secIps: 0:, vmID: 30, vmMAC: 06:84:18:00:00:11, vmName: i-2-30-VM, rules: eJzztCpJLrAysDIzNTU2tTLQA0N9Ax0/14gQBQBtngbl, signature: 86932b6a64104a3523f52531f0cdfbf4, due to There was a failure communicating with the plugin. 2013-11-01 07:58:57,115 WARN [agent.manager.DirectAgentAttache] (DirectAgent-124:null) Seq 3-1555238330: Exception Caught while executing command com.cloud.utils.exception.CloudRuntimeException: callHostPlugin failed for cmd: network_rules with args seqno: 1, vmIP: 195.238.173.20, deflated: true, secIps: 0:, vmID: 30, vmMAC: 06:84:18:00:00:11, vmName: i-2-30-VM, rules: eJzztCpJLrAysDIzNTU2tTLQA0N9Ax0/14gQBQBtngbl, signature: 86932b6a64104a3523f52531f0cdfbf4, due to There was a failure communicating with the plugin. I assume it's about the plugins existing on the Xen server but I don't know where to look further. Thanks, Daniel
