Managing virtual machines using the Web Console

Red Hat Hyperconverged Infrastructure for Virtualization 1.6

Perform common virtual machine management tasks in the Web Console

Abstract

After Red Hat Hyperconverged Infrastructure for Virtualization has been deployed, you can perform many operational and management tasks for virtual machines using the Web Console. Read this book to understand how to manage virtual machines using the Web Console.
This document explains how to perform maintenance tasks specific to Red Hat Hyperconverged Infrastructure for Virtualization.

Chapter 1. Understanding the Web Console

1.1. Understanding the oVirt Machines tab

The oVirt Machines tab provides an overview of the virtual machines running in the hyperconverged cluster.

To view this tab, browse to the the Web Console interface for your server (for example, http://server1.example.com:9090), log in, and click the hostname and oVirt Machines.

This tab is divided into a number of subtabs.

Host
The Host subtab shows information about virtual machines that are available on this hyperconverged host. Clicking on each virtual machine shows a summary of that machine, as well as various management operations. See Managing virtual machines using the Web Console for more information about virtual machine operations.
Cluster

The Cluster subtab shows information about virtual machines that are available in the hyperconverged cluster. The Host column lets you easily navigate to the appropriate location for managing each virtual machine. The Action column shows any operations you can perform from this hyperconverged host.

Templates

The Templates subtab shows the template images that you can use to create new virtual machines.

VDSM

The VDSM subtab shows the current contents of the vdsm.conf file and provides an easy way to edit the file’s contents. See VDSM and Hooks in the Red Hat Virtualization 4.3 documentation for more information about VDSM.

1.2. Understanding the virtual machine summary

In the Web Console, the Host subtab on the oVirt Machines tab shows information about virtual machines that are available on this hyperconverged host.

Clicking on each virtual machine shows a summary of that machine, as well as various management operations. The summary is divided into a number of sections that display different types of information and operations.

Overview

This section shows basic information about the virtual machine’s compute resources and capabilities.

oVirt

This section shows virtualization related information about the virtual machine and provides a way to migrate the virtual machine to another hyperconverged host. See Migrating a virtual machine to a different hyperconverged host using the Web Console for more details about migrating virtual machines.

Chapter 2. Managing virtual machines using the Web Console

2.1. Creating a virtual machine from a template using the Web Console

  1. Log in to the Web Console.
  2. Click the hostname, then click oVirt Machines → Template.
  3. Click the New VM button beside the template that you want to use.

  4. Specify a Name for your VM and click Create.

    Your new virtual machine is created on one of the hosts in your hyperconverged cluster.

2.2. Updating a virtual machine using the Web Console

You cannot currently update virtual machines using the Web Console.

See Upgrading to RHHI for Virtualization 1.6 for information about updating the Hosted Engine virtual machine using the Administration Portal.

See Updating Virtual Machine Guest Agents and Drivers in the Red Hat Virtualization 4.3 documentation for instructions on updating virtualization related software on a virtual machine using the Administration Portal.

2.3. Starting a virtual machine using the Web Console

  1. Log in to the Web Console.
  2. Click the hostname, then click oVirt Machines → Cluster.
  3. Click Run beside the virtual machine you want to start.

2.4. Pausing a virtual machine using the Web Console

  1. Log in to the Web Console.
  2. Click the hostname, then click oVirt Machines → Host.
  3. Click the virtual machine to pause.
  4. Click Suspend.

2.5. Resuming a virtual machine using the Web Console

  1. Log in to the Web Console.
  2. Click the hostname, then click oVirt Machines → Host.
  3. Click the virtual machine to resume.
  4. Click Resume.

2.6. Deleting a virtual machine using the Web Console

  1. Log in to the Web Console.
  2. Click the hostname, then click oVirt Machines → Host.
  3. Click the virtual machine to delete.
  4. Click Shut Down to shut down the virtual machine before deletion.
  5. Click Delete.
  6. Confirm deletion.

2.7. Shutting down a virtual machine using the Web Console

  1. Log in to the Web Console on the host that is running the virtual machine.
  2. Click the hostname, then click oVirt Machines → Host.
  3. Click on the virtual machine you want to shut down.

  4. Click Shut Down. This shuts the virtual machine down gracefully.

    If your virtual machine is not responding, click the dropdown arrow beside Shut Down and click Force Shut Down instead.

2.8. Migrating a virtual machine to a different hyperconverged host using the Web Console

  1. Log in to the Web Console.
  2. Click the hostname, then click oVirt Machines → Host.
  3. Click the virtual machine to migrate.

  4. Click the oVirt section.

  5. Specify a host in the dropdown menu, or use the default value of Automatically selected host.
  6. Click Migrate to and wait for the virtual machine to migrate.
  7. Click the Cluster subtab and verify that the virtual machine is now running on a different host.

2.9. Accessing the console of a virtual machine using the Web Console

  1. Log in to the Web Console.
  2. Click the hostname, then click oVirt Machines → Host.
  3. Click the Console subtab.

  4. Select a Console Type.

    1. For the Hosted Engine virtual machine

      The default console type for the Hosted Engine virtual machine is Graphics Console (VNC). The console loads after several seconds.
