SymptomsParallels Virtuozzo Containers for Linux 4.0 server with PIM 4.0 on board is shown as 'Stopped' in POA CP, while it is running and available.
CauseOnce of possible reasons of the issue could be corrupted VZAgent inside service container #1 on the HW node, which returns the following error:
# ssh email@example.com
<packet version="4.0.0"> <target>agent</target><data><error><code>"1"</code> <message>connect to /var/vzagent/vzlnpipe.sock failed: 2</message></error></data></packet>
Connection to 192.168.101.101 closed.
ResolutionTo solve the issue it is required to recreate Service Container #1 on the hardware server using instruction from the KB article, and update HW ID of the PVCfL server in POA database:
1. check HW ID of the PVCfL server inside its VZAgent config file /var/vzagent/etc/vzagent.conf:
2. save this ied in POA database for the specific PVCfL server using its ID shown in POA CP (in our example ID=7):
plesk=> update hw_nodes set eid ='12345678-1122-1111-1111-c11111cc1111' where host_id=7;
