Symptom

When importing or registering a Virtual Machine, an error may occur at Step 8 (NetworkName) due to a network mapping mismatch

 

Solution

Step 1. Login to VMware ESXi GUI (replace <your_ip_address_or_hostname> with the correct ip/hostname)

https://<your_ip_address_or_hostname>

 

Step 2. Shutdown and unregister the VM with the error

 

Step 3. Connect to the VMware ESXi CLI (“How to Connect to Vmware ESXi CLI”)

Step 4. Identify the vmx file location of the VM (replace <vm_name> with the vm name)

vim-cmd vmsvc/getallvms | grep -i "<vm_name>"

EXAMPLE OUTPUT

[root@localhost:~] vim-cmd vmsvc/getallvms | grep -i "Test"
1      Test   [Datastore1] Test/Test.vmx   windows2019srvNext_64Guest   vmx-21

 

Step 5. Make a backup of the vmx file (replace <datastore>, <vm_folder> and <vm_name> with the correct information from Step 4)

cp /vmfs/volumes/<datastore>/<vm_folder>/<vm_name>.vmx /vmfs/volumes/<datastore>/<vm_folder>/<vm_name>.vmx.bak

EXAMPLE

cp /vmfs/volumes/Datastore1/Test/Test.vmx /vmfs/volumes/Datastore1/Test/Test.vmx.bak

 

Step 6. Edit the VMX file and remove all lines starting with ethernet0 if any of those fields contains a -1 value (replace <datastore>, <vm_folder> and <vm_name> with the correct information from Step 4)

vi /vmfs/volumes/<datastore>/<vm_folder>/<vm_name>.vmx

EXAMPLE

vi /vmfs/volumes/Datastore1/Test/Test.vmx

Move cursor to the lines and press to delete

dd

Save and EXIT

:wq

 

Step 7. Retry to import or register the VM
