Continuing my series on provisioning VMs on workstation pro outside of the GUI, I’ve got a functional script that will create a linked clone using the vmrun command.
It allows you to specify the following options on the command line:
- Username in the provisioned VM
- Password in the provisioned VM
- Source Template
- Snapshot used for linked clone
- Name of new VM
It completes the following tasks
- Clones virtual machine
- Modifies the new VM’s VMX file to show the correct name
- Powers on the new VM (which also registers it to Workstation)
- Copies a script from the host to the VM as soon as VMware tools is available
- Copies output from the script from the VM to the host machine and prints output to the screen
- Prints the IP of the VM as soon as it’s available
The output looks like this:

$ ./workstation-clone-vm.sh --user root --pass [obfuscated] \
--template /storage/virtual_machines/Ubuntu_1810_Template/Ubuntu_1810_Template.vmx \
--snapshot base-4 --name test1
Parameters are:
User=root
Pass=[obfuscated]
Template Name=/storage/virtual_machines/Ubuntu_1810_Template/Ubuntu_1810_Template.vmx
Snapshot Name=base-4
New VM Name=test1
Cloning Ubuntu_1810_Template to test1 and using the snapshot: base-4
Powering on test1
Waiting for VMware Tools to start
..
Copying script to change the hostname from the host to the guest
Running custom script in test1 to set the hostname and rebooting
Waiting for VMware Tools to start
Copying output to local machine
Below is the output from the OS Customization:
Current hostname is ubuntu_1810_template. Hostname will be changed to test1
Waiting for the VM to return an IP Address
......
VM is running and has the IP Address: 192.168.102.131
