QCOW Deployment

Download Qcow2 Package

• Work with Aviz Sales/Support contact to create an account on Aviz Networks Support Portal

• Login to https://support.aviznetworks.com with your account credentials

• Click on the Downloads section, under ONES, click to download ONES Release 2.0

• Copy ONES Release 2.0 package (qcow2) to KVM Hypervisor Server

Create the VM using GUI App virt-manager

If your host server has Ubuntu Desktop and virt-manager installed you can use it to deploy the VM. Make sure you can start the Virtual Machine Manager and that it connects successfully to the local hypervisor.

Creating a VM with virt-manager is very straightforward, Use the following steps to deploy the ONES-Application

• File -> New Virtual Machine -> Import existing disk image -> Forward

Now the ONES Application is ready to use

Create the VM using QEMU (XML configuration)

• Create an XML configuration file from the following template using vi

vi ones.xml

User Inputs in XML File

Line #2   The Name of the VM
Line #3   The amount of System Memory for the VM
Line #4   The amount of System Memory for the VM
Line #5   The number of vCPU Core for the VM
Line #25  The Path to the qcow2 VM image file
Line #35  The name of the Linux bridge on the host machine

• Create a Linux bridge configuration file (bridged-network.xml) for libvirt from the following template

vi bridged-network.xml

<network>
    <name>br0</name>
    <forward mode="bridge" />
    <bridge name="br0" />
</network>

User Inputs in XML File

Line #4 the name of the Linux bridge on the host machine

• Define the Linux bridge for the VM

#Execute the below command to attach the VM to the Linux Bridge 
sonic@sonic-39:~$ virsh net-define bridged-network.xml
sonic@sonic-39:~$ virsh net-start br0
sonic@sonic-39:~$ virsh net-autostart br0
sonic@sonic-39:~$ virsh net-list
 Name                 State      Autostart     Persistent
----------------------------------------------------------
 br0                  active     yes           yes

sonic@sonic-39:~$ 

• Start the VM

virsh create <VM XML configuration file>

#sonic@sonic-39:~$ virsh create ones.xml 
#Domain ONES_VM01 created from ones.xml
#sonic@sonic-39:~$ 

If you see a permission error run the virsh command with sudo may fix the issue

• Check the VM status

sonic@sonic-39:~$ virsh list
 Id    Name                           State
----------------------------------------------------
 8     ONES_VM01                      running
sonic@sonic-39:~$
