Libvirt is an open-source API, daemon and management tool for managing platform
|
|
virtualization. There are several ways to deploy VyOS on libvirt kvm.
|
|
Use Virt-manager and native CLI. In an example we will be use use 4 gigabytes
|
|
of memory, 2 cores CPU and default network virbr0.
|
|

Deploy from ISO
|
|
---------------
|
|
|
|
Create VM name ``vyos_r1``. You must specify the path to the ``ISO`` image,
|
|
the disk ``qcow2`` will be created automatically. The ``default`` network is
|
|
the virtual network (type Virtio) created by the hypervisor with NAT.
|
|
|
|
.. code-block:: none
|
|
|
|
$ virt-install -n vyos_r1 \
|
|
--ram 4096 \
|
|
--vcpus 2 \
|
|
--cdrom /var/lib/libvirt/images/vyos.iso \
|
|
--os-type linux \
|
|
--os-variant debian10 \
|
|
--network network=default \
|
|
--graphics vnc \
|
|
--hvm \
|
|
--virt-type kvm \
|
|
--disk path=/var/lib/libvirt/images/vyos_r1.qcow2,bus=virtio,size=8 \
|
|
--noautoconsole
|
|
|
|
Connect to VM with command ``virsh console vyos_r1``
|
|
|
|
.. code-block:: none
|
|
|
|
$ virsh console vyos_r1
|
|
|
|
Connected to domain vyos_r1
|
|
Escape character is ^]
|
|
|
|
vyos login: vyos
|
|
Password:
|
|
|
|
vyos@vyos:~$ install image
|
|
|
|
After installation - exit from the console using the key combination
|
|
``Ctrl + ]`` and reboot the system.
|
|
|
|
Deploy from qcow2
|
|
-----------------
|
|
The convenience of using :abbr:`KVM (Kernel-based Virtual Machine)`
|
|
images is that they don't need to be installed.
|
|
Download predefined VyOS.qcow2 image for ``KVM``
|
|
|
|
.. code-block:: none
|
|
|
|
curl --url link_to_vyos_kvm.qcow2 --output /var/lib/libvirt/images/vyos_kvm.qcow2
|
|
|
|
Create VM with ``import`` qcow2 disk option.
|
|
|
|
.. code-block:: none
|
|
|
|
$ virt-install -n vyos_r2 \
|
|
--ram 4096 \
|
|
--vcpus 2 \
|
|
--os-type linux \
|
|
--os-variant debian10 \
|
|
--network network=default \
|
|
--graphics vnc \
|
|
--hvm \
|
|
--virt-type kvm \
|
|
--disk path=/var/lib/libvirt/images/vyos_kvm.qcow2,bus=virtio \
|
|
--import \
|
|
--noautoconsole
|
|
|
|
Connect to VM with command ``virsh console vyos_r2``
|
|
|
|
.. code-block:: none
|
|
|
|
$ virsh console vyos_r2
|
|
|
|
Connected to domain vyos_r2
|
|
Escape character is ^]
|
|
|
|
vyos login: vyos
|
|
Password:
|
|
|
|
vyos@vyos:~$
|
|
|
|
The system is fully operational.

|
Virt-manager
|
|
============
|
|
The virt-manager application is a desktop user interface for managing virtual
|
|
machines through libvirt. On the linux open
|
|
:abbr:`VMM (Virtual Machine Manager)`.
|
|
|
|
Deploy from ISO
|
|
---------------
|
|
|
|
1. Open :abbr:`VMM (Virtual Machine Manager)` and Create a new
|
|
:abbr:`VM (Virtual Machine)`
|
|
|
|
2. Choose ``Local install media`` (ISO)
|
|
|
|
.. figure:: /_static/images/virt-libvirt-01.png
|
|
|
|
3. Choose path to iso vyos.iso. Operating System can be any Debian based.
|
|
|
|
.. figure:: /_static/images/virt-libvirt-02.png
|
|
|
|
4. Choose Memory and CPU
|
|
|
|
.. figure:: /_static/images/virt-libvirt-03.png
|
|
|
|
5. Disk size
|
|
|
|
.. figure:: /_static/images/virt-libvirt-04.png
|
|
|
|
6. Name of VM and network selection
|
|
|
|
.. figure:: /_static/images/virt-libvirt-05.png
|
|
|
|
7. Then you will be taken to the console.

|
|
|
|
Deploy from qcow2
|
|
-----------------
|
|
|
|
Download predefined VyOS.qcow2 image for ``KVM``
|
|
|
|
.. code-block:: none
|
|
|
|
curl --url link_to_vyos_kvm.qcow2 --output /var/lib/libvirt/images/vyos_kvm.qcow2
|
|
|
|
|
|
1. Open :abbr:`VMM (Virtual Machine Manager)` and Create a new
|
|
:abbr:`VM (Virtual Machine)`
|
|
|
|
2. Choose ``Import existing disk`` image
|
|
|
|
.. figure:: /_static/images/virt-libvirt-qc-01.png
|
|
|
|
3. Choose the path to the image ``vyos_kvm.qcow2`` that was previously
|
|
downloaded . Operation System can be any Debian based.
|
|
|
|
.. figure:: /_static/images/virt-libvirt-qc-02.png
|
|
|
|
4. Choose Memory and CPU
|
|
|
|
.. figure:: /_static/images/virt-libvirt-03.png
|
|
|
|
5. Name of VM and network selection
|
|
|
|
.. figure:: /_static/images/virt-libvirt-05.png
|
|
|
|
6. Then you will be taken to the console.
