A simple metadata server to run cloud images on standalone libvirt :: KVM Hypervisor

With all the interest in Cloud Computing and virtualization, the OS vendors are providing ever more easier ways to deploy VMs. Most of them now come with cloud images. This makes it really easy for users to deploy VMs with the distro of their choice on a cloud platform like OpenStack or AWS. Here are … Continue reading

SSH Jump Host and Connection Multiplexing

Jump Hosts While working with libvirt as my primary hypervisor to launch test VMs I need a way to connect to the VMs easily over SSH. As libvirt uses private network and SNAT for connecting the VMs to external world getting SSH access to the VMs requires Port Forwarding or DNAT. I recently came to … Continue reading

Test-driving multiboot on Raspberry Pi – without BerryBoot/Noobs

Recently I got a Raspberry Pi 3 board and wanted to try out various OS options on it. I realized quite quickly that to try a new OS I would need to block copy (dd) the OS image to my SD card every time. I am running short on micro SD cards and it has … Continue reading

Test-Driving OSPF on RouterOS – Interoperability

So I wrote about OSPF on RouterOS in my previous post. It was a nice experiment to learn about routing protocols. I wanted to take it a little further and test Interoperability of RouterOS with other open source solutions. This post is an update from the previous one and I will add OSPF neighbor nodes … Continue reading

Test-driving OSPF on RouterOS

I came across RouterOS by MikroTik© which provides advances routing protocol support. What is more amazing is they provide a RouterOS in a virtual form-factor called Cloud Hosted Router (CHR) that can be installed on hypervisors like KVM/VirtualBox/VMware. Please look at licensing model at http://wiki.mikrotik.com/wiki/Manual:CHR#CHR_Licensing This is perfect for learning purposes and experimenting at home. … Continue reading
