It was about time I played with Open vSwitch (OVS). I’m going to take advantage of setting up a new server with Ubuntu Server, KVM, Virtual Machines, and VLANs to build everything with Open vSwitch instead of the traditional Linux Bridge. OVS is a virtual bridge from which I’ll manage all network connections for both the server itself and its virtual machines. Some VMs will receive a Trunk interface while the majority will connect in Access mode to a specific VLAN. …
The goal is to run virt-manager from my Mac to manage VMs on a couple of remote KVM/QEMU host servers without needing to install an X11 environment on them. I’ve documented two options: the first uses a local virtual machine (VirtualBox/Parallels/…) with Ubuntu and a minimal GUI environment (just Xorg/X11 and virt-manager), the second uses HomeBrew. …
Vagrant creates and runs virtual machines, relying on virtualization providers such as Virtualbox, KVM, Docker, VMWare, and 30+ others. It will always default to launching the VM with Virtualbox unless we explicitly specify a different provider. In this guide I explain how I set up Vagrant with the Libvirt KVM provider on Linux. …
I recently had to move a virtual machine from one of my servers to another on the same network. As always I relied on Google, although it’s a straightforward operation I do almost everything from the shell, so here’s the process for future reference… …
