Some one asked me howto power on Vmware Workstation guest machine via CLI. you can use vmrun tool to power on the machine by using target vm guest .vmx file. I decided to write the simple method for my reference too, because I also use it heavily in my virtual lab.
To achieve it, You can create a shortcut on your desktop so that you can quickly start your required workstation base virtual machine by clicking a single icon on your desktop. OR if you want to power it automatically after windows starts, you can create a simple shortcut or batch file and add it windows STARTUP.
You have install vmware workstation in H:\vmware_workstation and your guest vm is in H:\temp_images_ubuntu-proxy , then simply use the following shortcut.
D:\vmware_workstation\vmrun start D:\vmware_images\ubuntu-proxy\ubuntu.vmx
Tip: vmrun is available in workstation folder.
