Cause

Due to French locale settings in Windows OS Hyper-V Plugin does not recognize VMs.
WMI query in Powershell is not returning any VM: 

PS C:\Windows\system32>Get-WmiObject -Class Msvm_ComputerSystem -Namespace "root\virtualization\v2" -ComputerName <HYPER-V-NODE-NAME> | ? {$_.Caption -eq "Virtual Machine" } | select ElementName
PS C:\Windows\system32>

However, WMI query works if specify "Ordinateur virtuel"

PS C:\Windows\system32> Get-WmiObject -Class Msvm_ComputerSystem -Namespace "root\virtualization\v2" -ComputerName <HYPER-V-NODE-NAME> | ? {$_.Caption -eq "Ordinateur virtuel" } | select ElementName

ElementName
-----------
<VM_NAME_1>
<VM_NAME_2>
<VM_NAME_3>

Resolution

Issue resolved in Avamar 19.2 and later releases.
