Symptoms

Adding an ESX host to the vCenter Server inventory fails

If you try to add an ESX host to the vCenter Server inventory, you see an error similar to the following in vCenter Server:

A general system error occurred: internal error: vmodl.fault.HostCommunication.

The vpxd.log on the vCenter Server contains an entry similar to:

[2009-06-19 14:04:12.493 00664 error 'App'] [VpxdInvtHost] GetChanges failed on host /vpx/host/#2176/: vmodl.fault.HostCommunication

Restarting the ESX Management Agents does not resolve this issue.

Note: For more information, see Restarting the Management agents on an ESXi or ESX host (1003490).

Resolution

This issue may occur if name resolution is configured incorrectly.

To resolve this issue:

Verify that name resolution is correctly configured on the ESX host. For more information, see Identifying issues with and setting up name resolution on ESX/ESXi Server (1003735).

Verify that name resolution is correctly configured on the VMware VirtualCenter Server. For more information, see Configuring name resolution for VMware vCenter Server (1003713).

Verify that the version of ESX host is compatible with vCenter Server. For more information, see Adding an ESX/ESXi 4.1 host to vCenter Server 4.0 fails with the error: interal error:vmodl.fault.hostCommunication (1024381).

This issue may also occur if a Windows 2008 guest operating system is running on the ESX 3.5 Update 2 host, which is not supported. For more information, see the Compatibility Guide .

To resolve this issue, power off the virtual machine and then add the ESX host to the vCenter Server inventory.
