SymptomsService VE has been reinstalled on Virtuozzo node and now it is configured as Offline in HSPComplete.
CauseThe reason of this is that ssh keys which is used for Virtuozzo management through Vzagent have been recreated and do not correspond ssh key which HSPComplete has.
ResolutionThe simplest way in this case is to re-register hardware node in HSPcomplete system with entering vzagent0 password once again - in the same way as for VZMC:
To make so please login to HSPComplete, click on Connect button on the Top of Service Director, Virtuozzo Manager, Nodes, Hardware Node Name, General Settings screen and enter vzagent0 password.
After that HSPcomplete system should connect to the hardware node and upload new SSH keys once again.
