The following is a PowerShell code snippet to start multiple VMs through vmplayer.exe:
# Navigate to the folder where vmplayer.exe file exists
cd "D:\Program Files (x86)\VM Player"
# Start the VMs by using vmplayer.exe
<# vmplayer.exe command help
vmplayer.exe [OPTION…] [–] [configuration file]
where OPTIONS are:
-v show program version
-X Enter full screen mode when a virtual machine is powered on
-U Enter Unity when a virtual machine is powered on
-s NAME=VALUE Set Preference variable NAME to VALUE
The locations need to be changed based on your setup.
