2026-03-30 13:41:31,888 - INFO - TEST DESCRIPTION : 
        Test:- Test vdns functionality. On VM launch agent should dynamically update dns records to dns agent
            1.  Create vDNS server
            2.  Create IPAM using above vDNS data
            3.  Create VN using above IPAM and launch 2 VM's within it
            4.  Ping between these 2 VM's using dns name
            5.  Try to delete vDNS server which has IPAM back-reference[Negative case]
            6.  Add CNAME VDNS record for vm1-test and verify we able to ping by alias name
        Pass criteria: Step 4,5 and 6 should pass
