Symptoms

Converting Shared VPSs into Hardware Nodes fails with error:

Host key verification failed.'
2014-05-26 05:35:29.622  INFO <- Checking host host01.domain.tld (123) failed [00.124]
2014-05-26 05:35:29.622 ERROR Precheck error: There is no password, pubkey ssh access to host hwhost01.domain.tld (12)
You should: Provide no password, pubkey ssh access to host hwhost01.domain.tld (12)

However, passwordless account was configured properly between OA Management Node and Virtuozzo Hardware node.

Cause

HW node was registered in the past by old style via Service container IP address. In the current version such registration is impossible.

Resolution

  1. Check IP address of the service container on the HW node:

    # vzlist 1
CTID      NPROC STATUS    IP_ADDR         HOSTNAME                        
 1         77 running   10.0.5.47       ServiceCT

  2. Check that its IP is indeed shown as HW IP in OA database:

    plesk=> select host_id, agent_ip from hw_nodes where host_id = 12\x\g\x
Expanded display is on.
-[ RECORD 1 ]----+----------------------------------------
host_id          | 4
agent_ip         | 010.000.005.047
  3. If it is so, please contact Odin technical support to fix the issue in database.
