The CSR1000V-Router has already been prepared (Create a CSR1000V-Instance with nested Virtualiation support) and in (Part 4: Package the Service-VM into an OVA) we copied the OVA-Image of our „ubuntu-server“-VM to this Router. Add the internal Network-Interface between Router and Service-VM Install the Service-VM Activate the installed Service-VM Access the VM using the (virtual) Serial-Console Logout: 3x [CTRL]+ Access the VM using SSH via the internal Network Check the local python/NAPALM-Setup to get facts about the containing routerRead More →

I’ll start at the KVM-Virtualization Host („Ubuntu Desktop“) again. Folder Structure I’ll create a folder „isr-service-container“ for common stuff (package.yaml, create_ova.sh) and a for each VM a dedicated sub-folder, today: „ubuntu-server16.04“ Download the Cisco-provided „templates.tar“ from GitHub (GitHub: Templates.tar). It contains: package.yaml create_ova.sh Prepare a compressed virtual harddisk of the „Ubuntu-Server“-VM Locate the original virtual harddisk: Convert the original „.qcow2“-File into a compressed „copy“: Change the Owner of this new file: I’ll change: Description: „KVM Ubuntu 16.04 LTS“ resources/vcpu: 1 disk/file: ubuntu-server16.04.qcow2 The vCPU# got decreased since the CSR1000v only supports Service-VMs with one vCPU. Another File „version.ver“ has to be created: the „version“ mustRead More →

Network Hosted Kernel Virtual Machine (KVM) Many Cisco Routers allow you to host your own virtual machine directly inside a router. DevNet: Cisco IOS KVM Service-Containers CSR 1000v ISR 4000 ASR 1000 I went through the documentation, especially Service-Containers-Tutorial.pdf and Ubuntu – Building a Service Container.pdf where very helpful. But i didn’t want to go the „Ubuntu-Desktop-14.04-LTS“-way which was described. „My“ Service-Container-VM should be: Ubuntu 16.04 LTS provides longer support (April 2021) Releases – Ubuntu Wiki Ubuntu Server save some compute/cpu/dram/harddisk-ressources by not installing an Ubuntu-Desktop-Environment inside the Router. Just network services, please! The whole deployment process can be accomplished in five steps: build aRead More →
