Detailed Description

The oVirt Guest Tool ISO provides a collection of tools usable for Windows VMs that run under KVM (oVirt). It also includes an installer to make the tools installation as easy as possible.

The oVirt Guest Tools Installer installs all VirtIO-Win device drivers (Balloon, Serial, Net, Block and SCSI) along with Spice Agent and QXL drivers.

QXL support is also declared on Download page and should be kept in sync with above matrix.

The installer is based on the Spice installer’s source code (http://cgit.freedesktop.org/

teuf/spice-nsis/) , and was slightly modifed for this project’s needs.

Important Note! Bug 1528652 Currently you can’t directly upgrade between the versions without either first stopping the services or performing an uninstall.

The current list of the software to be included in the ISO:

• VirtIO-Win drivers:
  • VirtIO-Serial
  • VirtIO-Balloon
  • VirtIO-Net
  • VirtIO-Block
  • VirtIO-SCSI From:

  Spice drivers and agent

  Important Note! It seems that Spice installer (current is spice-guest-tools-0.132.exe ) installs not just Spice related components (QXL and Agent), but all VirtIO-Win drivers as well.
• Spice QXL for 32 and 64 bit Windows
• Qemu Guest Agent
• oVirt Guest Agent (Currently it is cross-compiled using Wine)

Benefit to oVirt

The ISO image will become a central repository for all the software that Windows based VMs require in order to function in most optimal way under oVirt / KVM.

oVirt-guest-agent

The agent is an application which run as a background process inside the guest, it communicates with Vdsm over a vioserial device. It provides:

Information

The agent provides the following information:

• Machine name – Show the virtual machine’s host name.
• Operating system version – Show the operating system’s version. Linux: this value is the kernel version. Windows: it is the Windows version name (e.g. Windows XP or Windows 7).
• Installed applications – List in installed applications. Linux: application list is set using the configuration file. Windows: installed applications list is based on value read from registry.
• Available RAM – The amount of unused physical memory. This value probably includes memory like cache, or else the memory usage will always be (or near) 100% usage.
• Logged in users – List of all logged-in users.
• Active user – The user that is currently using the virtual machine’s “physical hardware”. Redundant because RHEV-M is treating the SPICE’s ticket owner as the active user.
• Disks usage – VM disks utilization.
• Network interfaces – Internal guest network mapping (MAC, name, ipv4, ipv6).
• FQDN – Reports the configured (F)ully (Q)ualified (D)omain (N)ame of the guest os

Notifications

The agent notify on the following events:

• Power up – Sent when the agent is started.
• Power down – Unused.
• Heartbeat – The message sent every few second to notify that the agent is running. The notification includes the guest’s available RAM.
• User info – Active user has changed.
• Session lock – Desktop was locked (Windows).
• Session unlock – Desktop was unlocked (Windows).
• Session logoff – A user was logged off (Windows).
• Session logon – A user was logged on (Windows).
• Agent uninstalled – Agent was removed from the system. This is not sent by the agent itself but by the agent’s (un-)installer.

Actions

The following actions can be requested from the agent:

• Lock screen – Request locking the user’s desktop.
• Login – Perform a login on the user’s behalf.
• Automatic login on RHEL
• Automatic login on Microsoft’s Windows
• Logoff – Log off the active user.
• Shutdown – Shut down the virtual machine.

Download oVirt

oVirt 4.4.2 is intended for production use and is available for the following platforms:

• Red Hat Enterprise Linux 8.2
• CentOS Linux 8.2
• CentOS Stream (Tech Preview)

• Red Hat Enterprise Linux 8.2
• CentOS Linux 8.2
• oVirt Node (based on CentOS Linux 8.2)
• CentOS Stream (Tech Preview)

Install oVirt with Cockpit

oVirt is installed using a graphical installer in Cockpit.

oVirt Engine and a Host are installed together with the Engine running as a Virtual Machine on that Host. Once you install a second Host, the Engine Virtual Machine will be highly available. See the oVirt documentation for full details.

oVirt supports two types of Hosts:

Depending on your environment requirements, you may want to use only oVirt Nodes, only EL Hosts, or both.

Download oVirt Node

Download the oVirt Node Installation ISO (current stable is oVirt Node 4.4 — Stable Release — Installation ISO)

Write the oVirt Node Installation ISO disk image to a USB, CD, or DVD.

Boot your physical machine from that media and install the oVirt Node minimal operating system.

Or Setup a Host

Instead of or in addition to oVirt Node, you can use a standard Enterprise Linux installation as a Host.

Install one of the supported operating systems (CentOS, RHEL) on your Host and update it:

Add the official oVirt repository:

Install oVirt using the Cockpit wizard

Enable the Base, Appstream, and Ansible repositories (Red Hat Enterprise Linux only):

Install Cockpit and the cockpit-ovirt-dashboard plugin:

Log in to Cockpit as root at https://[Host IP or FQDN]:9090 and click Virtualization → Hosted Engine.

Click Start under the Hosted Engine option.

Complete the setup wizard. As part of the setup, you will enter the Hosted Engine’s name.

As part of the setup wizard, you will need to provide the location of your storage. oVirt requires a central shared storage system for Virtual Machine disk images, ISO files, and snapshots.

Once the installation completes, oVirt’s web UI management interface will start. Browse to https://[Hosted Engine’s name]/ to begin using oVirt!

See Browsers and Mobile Clients for supported browsers and mobile client information.

Setup Additional Hosts

Once the Engine is installed, you must install at least one additional Host for advanced features like migration and high-availability.

Once you have installed additional oVirt Nodes or EL Hosts, use the oVirt Administration Portal to add them to the Engine. Navigate to Compute → Hosts → New and enter the Host details. See Adding a Host to the oVirt Engine for detailed instructions.

Install Virtual Machines

Once oVirt Engine is installed and you have added Hosts and configured storage, you can now install Virtual Machines! See the Virtual Machine Management Guide for complete instructions.

For best Virtual Machine performance and accurate dashboard statistics, be sure to install the oVirt Guest Agent and Drivers for Linux [for Windows] in each Virtual Machine.

The following virtual machine guest operating systems are supported:

[1] SPICE drivers (QXL) are not supplied by Red Hat. Distribution’s vendor may provide SPICE drivers.
[2] select Other Linux for the guest type in the user interface
[3] not tested recently (?)

Consoles

The console is a graphical window that allows you to view and interact with the screen of a Virtual Machine. In oVirt, you can use a web-based console viewer or a desktop application (we recommend Remote Viewer). For Windows virtual machines, Remote Desktop Protocol is also available. See Installing Console Components, VNC Console Options, and and Browser Support and Mobile Clients for more information.

RPM Repositories and GPG keys

See RPMs and GPG for older releases, nightlies, mirrors, and GPG keys.
