After the deploy of 3 Nested Nutanix CE VM’s, we need to create a Nutanix cluster.

 Connect to one of Nutanix CVM Console

a) Create the cluster:


The process discovers 3 nodes:


The process configures Zeus mapping on 3 nodes:

With the message:


CVM is trying to contact the host KVM and being unsuccessful

Restart Genesis services on 3 nodes:


Check the errors on genesis log : tail -f genesis.out


Log on each KVM host


Run : sshd-keygen on each KVM host


Log on each CVM :

Run : cluster –f destroy

Try to recreate the cluster !

2 Validate Nutanix Cluster status

After creating a cluster ensure everything is working successfully.

Log onto one of CVM:

Run a diagnostics test with the command:

Test latency stats and IO stats for random/sequential reads/writes and network performance


Check the cluster status (if all services are UP) :

Run command:
