  • Virtuozzo containers for Windows 4.5


There are two existing SWsoft Virtual Network Adapters on the node which results various unpredictable issues. For example Service Container creation might fail with the following error:

Failed to invoke "C:\Program Files (x86)\Parallels\Containers\VZAgent\\bin\vzlInstallHelper.exe" addGroup "Parallels Infrastructure Manager Users".


Hyper-V role is added on the server after PVC installation and then PVC is reinstalled. As consequence two SWsoft Virtual Network Adapters appear on the system.


Remove extra 'SWsoft Virtual Network Adapter'.
