Resolved Issues

  • The Shared USB Yubikey Driver ends abnormally and generates dump files when the VM is shutdown.

    The Shared USB Yubikey Driver ABENDs (Abnormal end of task) and generates a log and dump files, when the VM is shutdown. This issue doesn't occur on a restart or a force shutdown.

    This issue is now resolved.

  • The Windows Operation System stops working without any message when trying to connect an USB Devices to the VM

    The Windows Operation System stops working without any message and freezes when some USB devices are connected to the VM.

    This issue is now resolved.

  • The Virtual Network name doesn't support multi-byte characters

    Using a multi-byte character Virtual Network name in the Virtual Network Editor, crashes the Workstation and the Virtual Network Editor UI and makes them un-launchable.

    This issue is now resolved.

Known Issues

  • VMware Workstation 15.5.5 installation fails on a Windows Host which doesn't have SHA-2 code signing support

    Workstation installation on a Widows Host fails with an error and the changes are rolled back. 
    Microsoft have changed Windows driver signing to use the SHA-2 algorithm exclusively and starting from September 2019, legacy Windows systems without SHA-2 code signing support will fail the driver signature verification. 

    None. For more information, see https://kb.vmware.com/s/article/78655.

  • Virtual machines with a bridged type network connection doesn't bind its network to the host's physical network adapter

    By deafult, the Workstation's Bridged Network selects a host's network adapter automatically to bind. If the host system has a virtual network adapter (For example: Microsoft Loopback Adapter, Hypver-V Virtual Ethernet Adapter, etc.), sometimes the Bridged Network will bind to these virtual network adapters instead of physical network adapter.

    Disable automatic binding and assign the physical network adapter to the Bridged Network by performing the following steps:

    1. Open the Virtual Network Editor by navigating to Workstation UI > Edit > Virtual Network Editor.
    2. Click Change Settings and select VMnet0.
    3. Select the Physical network adapter's name instead of Automatic in the Bridgedto drop-down list.
    4. Click OK to save.
  • The Guest VBS feature is not supported in Host VBS mode

    In the Host VBS mode environment, when the Guest VBS feature is enabled on a Win10 VM by navigating to VM Setting > Options > Advanced > Enabled VBS Support. The VM fails to power on and displays the VMware Workstation does not support nested virtualization on this host error.
