Create a new Red Hat Enterprise Linux virtual machine named rh1 in cluster1. Use the Red Hat Enterprise Linux 7.6 boot ISO image, created at the start of this exercise. A Kickstart answer file has been provided at http://materials.example.com/static/small-7.6.cfg. Remember that you can use the Administration Portal to access the console of the virtual machine.

Create a 3 GiB disk image for this virtual machine. Specify the Instance Type as Tiny, and set 512 MB as the maximum memory of the virtual machine. Select Server as the value of the Optimized for field of the rh1 virtual machine. Associate the virtual machine's first NIC with the ovirtmgmt logical network. Associate the virtual machine's second NIC with the virtual logical network.

1. Log in to the RHV-M Administration Portal as admin from the internal profile, using redhat as the password. The URL for the Administration Portal is https://rhvm.lab.example.com.

2. From the menu, navigate to Compute → Virtual Machines to access the Compute >> Virtual Machines page.

3. In the Compute >> Virtual Machines page, click New to create a new virtual machine. The window titled New Virtual Machine displays. In the New Virtual Machine window, under the General section, set the values of the fields according to the following table.

   Field	Value
   Cluster	cluster1
   Template	Blank | (0)
   Operating System	Red Hat Enterprise Linux 7.x x64
   Instance Type	Tiny
   Optimized for	Server
   Name	rh1

4. In the New Virtual Machine window, click Create near to Instance Images. The window titled New Virtual Disk displays. In the New Virtual Disk window, specify 3 as the value of the Size (GiB) field. Leave all the other fields with their default values, and click OK to confirm creating the virtual disk of 3 GiB in size for the rh1 virtual machine.

5. In the New Virtual Machine window, under the General section, click the drop-down menu for nic1. From the menu that appears, select ovirtmgmt (ovirtmgmt) to associate the first NIC of rh1 with the ovirtmgmt logical network.

6. In the New Virtual Machine window, under the General section, click the + button that is displayed in the same row as nic1. A second row displays with the nic2 drop-down menu. Click on the drop-down menu for nic2, and select virtual (virtual) to associate the second NIC of rh1 with the virtual logical network.

7. In the New Virtual Machine window, click on Show Advanced Options and navigate to the System section. Change the value of the Maximum memory field to 512 MB. Click OK to confirm your intention to create the virtual machine with the defined properties.

Modify the parameters of rh1 to use the rhel-server-7.6-x86_64-boot.iso as the bootable media at its next boot, and invoke the Kickstart installation of rh1. Use the answer file available at http://materials.example.com/static/small-7.6.cfg for the Kickstart installation.

1. Click on the row for the rh1 virtual machine. Click on the drop-down menu next to the Run button. From the menu that displays, select Run Once. The window titled Run Virtual Machine(s) displays.

2. In the Run Virtual Machine(s) window, click the + sign next to Boot Options. Select the check box next to Attach CD to use the displayed rhel-server-7.6-x86_64-boot.iso file as the bootable media for rh1. Selecting this check box inserts the ISO file into the virtual CD-ROM/DVD-ROM drive of rh1.

3. Under Predefined Boot Sequence, select CD-ROM and click Up to bring CD-ROM to the top of the list. Click OK to confirm the changes you made, and to boot the rh1 virtual machine. Wait until the Console button becomes active.

4. With the rh1 virtual machine selected, click Console to access the console of rh1. The Opening console.vv window opens and prompts for your confirmation to open the connection file (console.vv). Click OK to open the console.vv file using Remote Viewer. Wait until the installer menu displays in the console of rh1.

   Note

   If Remote Viewer prompts for your confirmation to inhibit shortcuts, click Allow.

5. From the installer menu that is displayed in the console of rh1, highlight the Install Red Hat Enterprise Linux 7.6 and press Tab to edit the installer options.

   The editor opens with the cursor automatically positioned at the end of the existing kernel arguments. At the end of the kernel command line, add a space and the argument inst.ks=http://materials.example.com/static/small-7.6.cfg to specify the location of the answer file to use for the Kickstart installation. Press Enter to start the Kickstart installation of the rh1 virtual machine.

6. Watch for the installation to complete. After the installation completes, the virtual machine automatically reboots from the CD-ROM drive. Press an arrow key to interrupt the timer for preventing the installer to invoke the installation process.

7. Close the console of the rh1 virtual machine.

8. Right-click on the row for the rh1 virtual machine, and select Power Off. The window titled Power Off Virtual Machine(s) displays. In the Power Off Virtual Machine(s) window, click OK to confirm your intention of powering down the virtual machine.

Verify that the qemu-guest-agent package is installed on the rh1 virtual machine. Start the qemu-guest-agent service in rh1. Use the file located at http://materials.example.com/yum.repos.d/rhel_dvd.repo to enable the package repository that provides the qemu-guest-agent package.

1. In the Compute >> Virtual Machines page, select the rh1 virtual machine, and click Run. Wait for the value of the Status field to transition from Wait For Launch to Up with Powering Up in between.

2. After the virtual machine is started, click Console to access the console of rh1. The Opening console.vv window opens and prompts for your confirmation to open the connection file (console.vv). Click OK to open the console.vv file using Remote Viewer.

   Note

   If Remote Viewer prompts for your confirmation to inhibit shortcuts, click Allow.

3. Log in to rh1 as root with the password redhat.

4. Download the repository configuration file from http://materials.example.com/yum.repos.d/rhel_dvd.repo as /etc/yum.repos.d/rhel_dvd.repo.

   [root@rh1 ~]# curl http://materials.example.com/yum.repos.d/rhel_dvd.repo \
   -o /etc/yum.repos.d/rhel_dvd.repo

   Note

   The shell prompts that you see may vary from the book.

5. Use yum to verify the package repository on rh1.

   [root@rh1 ~]# yum repolist
   Loaded plugins: product-id, search-disabled-repos, subscription-manager
   This system is not registered with an entitlement server. You can use subscription-manager to register.
