Getting Rockstor to work in a VM for vSphere/ESXi Deployment

•    Rockstor will not always work with vSphere/ESXi in a VM format. You will have to edit one file after you deploy/install your Rockstor VM.
•    The first step is to navigate to the data store on your ESXi data store. You need to open the VMs folder directory.
•    Within the VM folder directory of your Rockstor VM, click on the .vmx file and download this (this is just the .vmx file which is for VM customization).
•    Once the file is downloaded, open the file in Notepad++ or another notepad type file, and add the following line in the .vmx file Do not use the enclosing quotes, only use the quotes around the TRUE statement:
    o    “disk.EnableUUID=”TRUE””
•    Once this has been changed, save the file.
•    Navigate back to your VM data store and VM folder directory.
•    Click on the Upload link in the top right of the folder directory.
•    Select the new .vmx customized file and upload it.
•    You might also have to do these steps in vSphere to finish the TRUE statement if it does not take:
    o    Right click on the VM.
    o    Click on the VM Options tab.
    o    Click on the Advanced section.
    o    Click Edit Configuration tab.
    o    In the disk.EnableUUID, change from FALSE to TRUE.
•    Now, Rockstor is ready to be used as a VM in your environment.
