Cmdlet Contention between PowerShell SnapIns

Question

I ran into an issue while using both the Vmware PowerCLI and System Center Virtual Machine Manager snap-ins for PowerShell. They both contain similarly named cmdlets, like 'Get-VM' and 'Get-VMHost'. It appears that the last snap-in to load wins, so I added logic in my script to load & un-load the snap-in when I needed to get either VMware data or Hyper-V data. I'd like to know if there is any way to prevent this contention, or otherwise create some unique handle to one cmdlet, while still allowing the other to load & operate as intended?

The best approach when using snapins is to fully qualify the cmdlet name with the snapin name. For instance, if the snapin name for PowerCLI is PowerCLI then use:

PowerCLI\Get-VM

For the SCVMM snapin use it's name as a prefix. To see the snapin names, execute:

Get-PSSnapin -Registered
