Here is an example of how to make automated VM’s with PowerCLI. You can customize the vLAN, DiskType, etc.
If you reuse the Script below, I would recommend to look at the parameters and adapt them to your environment, e.g. network/storage config like the vLan,ESXI Hosts or the adapter type you are using its VMWare.
example:
|
1 |
Create-CustomVirtualMachine -Hostname 'MyServer' -NumCPU 6 -DiskSize 80 -RAMinGB 12 -OS Srv2016 |
Ensure you are using this script with PowerCLI or with the PowerCLI Module / Assemblys.
The script can also be saved and imported as a module (.psm1).
|
1 |
Import-Module "Path:\to\your\module\share\Create-VM_onFreeDatastore.psm1" -Verbose |
