How to create a KVM VyOS root filesystem for VNX

Installation

VyOS is an open source network operating system that is based on Debian GNU/Linux and that joins multiple applications such as Quagga, ISC DHCPD, OpenVPN, StrongS/WAN and others under a single management interface. It can be installed on physical hardware or on virtual machines and it is a community fork of Vyatta.

Follow this procedure as a root user to create a VyOS based KVM root filesystem for VNX. The procedure has been tested with VyOS 1.1.7 over a Ubuntu 16.04 system.

• Create the filesystem disk image:

qemu-img create -f qcow2 vnx_rootfs_kvm_vyos64-1.1.7-v025.qcow2 8G

• Get VyOS installation CD:

wget http://packages.vyos.net/iso/release/1.1.7/vyos-1.1.7-amd64.iso
cp vyos-1.1.7-amd64.iso /almacen/iso

• Create the virtual machine with:

vnx --create-rootfs vnx_rootfs_kvm_vyos64-1.1.7-v025.qcow2 --install-media /almacen/iso/vyos-1.1.7-amd64.iso --mem 512M --arch x86_64

• Login with vyos/vyos and execute:

install image

• Answer all the installation questions with the default values. Once installed, stop the virtual machine with:

poweroff

• Restart the VM with:

vnx --modify-rootfs vnx_rootfs_kvm_vyos64-1.1.7-v025.qcow2 --update-aced --mem 512M --arch x86_64

• Install VNX autoconfiguration daemon:

sudo su
mount /dev/sdb /mnt/
perl /mnt/vnxaced-lf/install_vnxaced

• Create a file /etc/vnx_rootfs_version to store version number and informacion about modification:

VER=v0.25
OS=VyOS (Debian 6.0.10 64 bits)
DESC=Basic VyOS Linux based network operating system (Debian 6.0.10 64 bits) root filesystem

• Enter using vyos/vyos user/password and create the vnx/xxxx user and enable ssh access with:

exit   # to exit 'sudo su' and come back to user vyos
configure
set system login user vnx full-name "VNX project"
set system login user vnx authentication plaintext-password xxxx
set system login user vnx level admin          
set service ssh port 22  
commit
save
exit

• Stop the machine with vnx_halt:

sudo vnx_halt

Testing

You can test the rootfilesystem with the following tutorial example:

vnx -f /usr/share/vnx/examples/tutorial_vyos.xml -v -t
