To create virtual machines:
Figure 96. OVM VM creation – open wizard
Note: A Microsoft Windows operating system requires additional steps because the VirtIO drivers are not present to discover the virtual disk for install. These drivers are available in any number of repositories online along with instructions about how to implement them.

Leave the checkboxes in their default state and click OK to return to the General dialog.

The user can add as many disks as wanted, though only one can be Bootable. The virtual machine defaults to one vCPU and 1 GB RAM.
The virtual machine creation time depends on the number of virtual disks that are created, their size, and whether they are preallocated.
Note: Although it can be assigned during the virtual machine creation, OVM offers the ability to attach the ISO so it is only used for the first power on.
The following dialog is displayed, as shown in Figure 100:

The virtual machine boots to the ISO.

If the Virtual Machine Viewer is not associated with the .vv extension, the browser prompts the user to save a file named console.vv. The user must then associate the file extension with the console viewer.
The user can now proceed with the operating system installation.
After the installation completes and the virtual machine reboots, OVM places an exclamation point next to the virtual machine indicating that the latest guest agent must be installed, as shown in Figure 103. The guest agent is required to enable functionality such as displaying the IP/FQDN, gracefully powering off the VM, and providing resource information.

The Virtual Machine Management Guide provides instructions for installing the agent depending on the operating system. For Enterprise Linux 8, like Rocky, run the following commands:
yum install qemu-guest-agent
systemctl start qemu-guest-agent
systemctl enable qemu-guest-agent
oVirt supports adding multiple logical networks to physical NICs on the KVM node, including those networks with VLAN tagging. Because VLANs are used for file storage in this guide, the following steps show how to add a new logical network with VLAN tagging:
oVirt then configures the network on the host.
The logical network is created and configured, as shown in Figure 110:
