Resolution

The installation process for Windows guest tools has changed in RHV 4.4. Previous versions of RHV used InstallShield to install the Windows guest tools in the rhv-guest-tools-iso package. InstallShield is proprietary software and it is replaced by the Windows installer (WIX), using .msi files. The .msi installer is provided with the virtio-win package.

Note: those instructions are also available in RHV 4.4 virtual machine guide.

• To install the guest agents, tools, and drivers on a Windows virtual machine, complete the following steps:
  • On the RHV-M (RHV Manager) machine, install the virtio-win package:
  • Install the required packages on the+ RHV-M (RHV Manager)

yum -y install virtio-win

* After you install the package, the ISO file is located in `/usr/share/virtio-win/virtio-win.iso` on the RHV-M machine. The file is a symbolic link to the latest version of the virtio-win iso file.
* Upload the file to a data storage domain. See the chapter [Uploading Images to a Data Storage Domain](https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.4/html-single/administration_guide/index#Uploading_Images_to_a_Data_Storage_Domain_storage_tasks) In the Administration Guide for details.
* In the Administration or VM Portal, if the virtual machine is running, use the *Change CD* button to attach the iso file to each of your virtual machines. If a virtual machine is powered off, click the *Run Once* button and attach the ISO as a CD.
*  Login to the virtual machine.
    *  Select the CD Drive containing the iso file. You can complete the installation with either the GUI or the command line.
        * GUI
            * Run the installer.
            * Double-click `virtio-win-gt-x64.msi` or `virtio-win-gt-x86.msi`.
            * Click *Next( at the welcome screen.
            * Follow the prompts in the installation wizard. Ensure all check boxes in the list of components are selected, including the *RHEV Agent*, which is disabled by default.
            * When the installation is complete, select *Yes, I want to restart my computer now* and click *Finish* to apply the changes.
        * Command line.
            * Open a command prompt with Administrator privileges.
            * Enter the cmd `msiexec` command:

                    D:\ msiexec /i "_PATH_TO_MSI_" /qn [/l*v "_PATH_TO_LOG_"][/norestart] ADDLOCAL=ALL

• After installation completes, the guest agents and drivers pass usage information to the RHV-M and enable you to access USB devices, single sign-on into virtual machines, and other functionality. The RHV guest agent runs as a service called RHEV Agent that you can configure using the rhev-agent configuration file located in C:\Program Files\Virtio-Win\RHV_Agent.
