Questions about UUID

Hi,

I'm wondering if there's a way to find out all the UUID's of all my VMs using PowerCLI.

A lot of VMs where copied by some users on my organization to another host/datastore using other tools/commands and when they turned on the machines they were choosing "I copied it" and "I moved it" randomly.

Need to check out to see if there's nothing wrong in my environment.

Also, using PowerCLI, when I get information of some VM, it shows an ID field. Something like: VirtualMachine-38

There is a lot of VMs with same ID, does this implicate on something wrong?

Thanks in advance.
