I'm running ESXi 6.0.0 in free mode. I created one VM and then copied its files to another folder in the datastore to create the next machine (almost like a template). I wound up with two working VM's that have been doing just fine in production.
My backup drives finally came in, so now I'm trying to set up Unitrends to do VM level backups. When I try to connect Unitrends to ESXi, it gives an error:
Virtual machines "vm1name" and "vm2name" have the same Instance UUID. Please use the VMware vSphere Client or another administration tool to assign a new UUID to one of the virtual machines.
According to the advice on this forum post: I tried to edit the VMX file to change the bios.uuid value. That didn't resolve the error. Next I tried to use the script form the same post in PowerCLI. It showed me that I do indeed have duplicate instance UUID's. These are apparently different from the UUID values in the vmx file (which are unique). I have two machines that both have the instance UUID of
Unforrunately, it seems that I can't find a way to change the instance UUID. I haven't been able to find anything about it online.
How do I change the Instance UUID for a virtual machine on ESXi? I really must get it working, and I'd appreciate any help you can provide. Thank you!
