A Virtuozzo-related task fails with the following error message:

Cannot connect to VZAgent: address XXX.XXX.XXX.XXX (IP of VZ HW Node)

For example:

Task name Migrate VPS (host_id: XXXX) from HN (host_id: YYYY) to HN (host_id: ZZZZ)
Task description Task that performs VPS migration
Subscription ID 1018444
Parent task ID 85
Queue status Failed
Start not earlier than Dec-02-2013 19:00
Method name taskVPSMigration on OBJREF:VPSTasks:0:getVPSMigrationManager:0
Last execution output Cannot connect to VZAgent: address XXX.XXX.XXX.XXX> 


The connection from the Parallels Operations Automation (POA) core server to the Virtuozzo Hardware Node cannot be established using the IP address mentioned in the error message. You can check this with the telnet utility, which can be launched from the POA core server:

[root@osscore ~]# telnet XXX.XXX.XXX.XXX 4434
telnet: connect to address XXX.XXX.XXX.XXX: No route to host


Make sure that the Virtuozzo Hardware Node is accessible from the POA core server and PVA Agent is listening on the mentioned IP address:

[root@vzlin0X ~]# netstat -antp | grep 4434
tcp        0      0      *                   LISTEN      2387/pvaagent [gend
tcp        0      0 :::4434                     :::*                        LISTEN      2387/pvaagent [gend
