Hi,

I have deployed a single node Nutanix CE, the deployment is done, and I am able to reach the AHV IP address but the CVM IP address is unreachable. However the CVM is reachable from the AHV when ssh. Unable to resolve the issue.

I tried doing a virtual three node cluster with CE on ESXi but could never get the three host to reliably talk to each other to build the cluster.  1 out of the three host’s CVM would always be unreachable.  I single node cluster works.  I simplified to a single nic on the ESXi host for the vswitch to ensure it wasn’t a network issue.  I did make the changes to Accept for Promiscuous, Mac address changes and Forged transmits.

You can try a “trick” - run pings between hosts and CVMs, to update mac address table. 

Once all CVMs are “pingeable”, try to create a cluster.

Thanks, it worked.

Enable all three security settings on the portgroup

The AHV IP address is reachable from AHV I can SSH into the CVM, and yes the promiscuous mode was disabled and now enabled but still the CVM is not reachable.

You need to enable promiscuous mode on the portgroup in VMware.

how do you ssh from AHV to CVM?

Hi,

I have not configured an external IP address, the Nutanix CE is running on a vmware environment.

What’s your network configuration? My assumption is that you make a connection from the AHV host to the CVM using the external ip address….
