Add Compute Host to oVirt Virtualization - How to do it

This article covers oVirt Virtualization and how to add Compute Host to oVirt Virtualization. oVirt is a free and open-source distributed virtualization solution that can be used to manage your entire infrastructure.

oVirt allows you to manage virtual machines, compute, storage and networking resources from the web-based interface. It uses KVM hypervisor and built upon several other community projects, including libvirt, Gluster, PatternFly, and Ansible.


To Add Compute Host to oVirt:

1. Validate oVirt Engine installation by logging into the console.

2. Navigate to Compute > Hosts > New and fill all required information.

3. Modify other settings in the left panel as you see fit and click "OK" button to provision the node.

4. The Status should change to Installing and will finish in few minutes.


To Configure Host Networking:

1. If you want to add additional networks – extra bridges with VLANs e.t.c, this can be done once the host is added.

2. First create a Logical Network on Network > New. Give Virtual Network correct details. For VLAN ID check "Enable VLAN tagging".

3. With the Host added and active you can configure its networking under Network Interfaces > Setup Host Networks.

4. Assign the Logical network to an interface.

5. Drag Virtual Network for mapping to host interface.

6. Configure IP addressing if required.

7. Once saved and successful it should turn green.

8. You can then proceed to create virtual machines using oVirt Management interface.

oVirt Server unable to upload image to disk

This article will guide you on ways to resolve 'ovirt: unable to upload image to disk' error.

You can upload virtual disk images and ISO images to your data storage domain in the Administration Portal or with the REST API.

QEMU-compatible virtual disks can be attached to virtual machines. Virtual disk types must be either QCOW2 or raw. Disks created from a QCOW2 virtual disk cannot be shareable, and the QCOW2 virtual disk file must not have a backing file.

ISO images can be attached to virtual machines as CDROMs or used to boot virtual machines.


To Upload an Image to a Data Storage Domain:

1. Click Storage - Disks.

2. Select Start from the Upload menu.

3. Click Choose File and select the image to upload.

4. Fill in the Disk Options fields.

5. Click OK.

A progress bar indicates the status of the upload. You can pause, cancel, or resume uploads from the Upload menu.

Virtual Machines (VMs) in oVirt 4 0 Environment

This article will guide you on the steps to create a Virtual Machines (#VMs) in oVirt 4.0 Environment.

The #oVirt engine acts as the control center for oVirt environments. The engine enables admins to define #hosts and #networks, as well as to add storage, create VMs and manage user permissions. Included in the oVirt engine is a graphical user interface (GUI), which manages oVirt #infrastructure resources.

To Create a Virtual Server:

i. Access the Virtual Server class tab in the Class #Manager.

ii. Click the Add Virtual Server link.

iii. Specify the name of the virtual server, its connections, and the URL Hosts. ...

iv. Click OK and then Apply to save and apply your changes.

To to Create Virtual Machines (VMs) in oVirt 4.0 Environment:

1. Create new Data Center.

2. Configure Cluster for Data Center.

3. Add Host or oVirt Node to above created data center & cluster.

4. Creating Storage #Domains.

5. Upload #ISO files to ISO Storage Domain.

6. Create Virtual Machine.
