Get-VM powershell not return results

Hello,

I have one problem. I have install powershell into vm windows and into vm linux. In vm linux, the command Get-VM return al VM present, while in vm windows, the command Get-VM not return results.

I also use the command : Get-VM -Server $VIserver -Name 'myvm' and in Linux I have the result of vm, but in windows i have this message: Get-VM VM with name 'myvm' was not found using the specified filter(s).

The command start-vm and stop-vm they work in all environments.

Oh I forgot, the command Get-Inventory in windows, return all VM. Can someone help me? Thanks.
