How to Fix: vSphere error when powering virtual machine

The error 'Failed to start the virtual machine (error-18)' indicates that the vSphere setup is unable to configure the virtual machine according to the rules specified in /etc/vmware/configrules. This issue affects users who have successfully installed VMware and vSphere on their local machine, added VMX files from datastore to inventory, but are experiencing this specific error when powering up a virtual machine.

This error can be frustrating for administrators as it prevents them from starting the virtual machine, which is essential for their work. However, by following the steps outlined in this guide, you should be able to resolve the issue and get your virtual machine up and running.

🔍 Why This Happens

• The primary reason for this error is that the VMX file path '/disk2/vmserver/hdisks/hpbsni_3ndDisk_tmpDB.vmdk' does not match the configuration key 'scsi0:4.fileName'. The value was not accepted by the rule 'Virtual SCSI Devices', indicating a mismatch between the specified path and the expected format.
• An alternative reason for this error could be that the VMX file path '/disk2/vmserver/hdisks/hpbsni_2ndDisk.vmdk' does not match the configuration key 'scsi0:3.fileName'. This also results in an invalid value being accepted by the rule, leading to the same error.

🎯 Final Words
