I saw a blog for getting a VMhost UUID. UUID is sometimes needed. In my case I needed it to license EMC Powerpath VE.
There's a an easy way than going through all that.
Get-VMhost | Get-View | % { $_.hardware.systeminfo.uuid }
That's it. If you want to get fancy and have a need for speed (if you have many VMhosts):
Get-View -ViewType HostSystem -Propert Name, hardware.systeminfo -Filter @{"Name"="VMHostNameHere" } | % { $_.hardware.systeminfo.uuid }
If you want to get even fancier and return the host name with the UUID, here's a little trick using SELECT:
Get-View -ViewType HostSystem -Propert Name, hardware.systeminfo -Filter @{"Name"="VMHostNameHere" } | Select Name, @{N="UUID" ; E={$_.hardware.systeminfo.uuid } }
Notice the "N=" and "E=" clauses? N means NAME and E means expression.
