![]() We don't put it in another partition to avoid any error. For example, we have /home/master/Downloads directory, and we put the ISO there. You better place the ISO image in the same partition as your $HOME partition.Tools used in this tutorial are KVM as the hypervisor (kernel-space), QEMU as the machine emulator (user-space), and Virtual Machine Manager (virt-manager) as the display GUI.We want to install Ubuntu 16.04 Xenial Xerus 32 bit inside a QEMU/KVM virtual machine.Our hardware specification is Intel Celeron 1.8 GHz 32 bit, 2 GB RAM, 12 GB free space. ![]() This article is a continuation of our previous tutorial about installing QEMU/KVM and virt-manager in Ubuntu. There are only 5 steps to prepare the virtual machine, after that the 6th step is the guest OS installation. The GUI displayed by Virtual Machine manager (virt-manager). We will install Ubuntu 16.04 as guest on top of Ubuntu 16.04 as host. ![]() Is there a way to dump the verbose output at startup to a file for examination later on? Feels like the qemu-kvm or libvirt install is breaking the default networking config, or somehow interfering with netplan implementation on startup.We want to give an example about installing an operating system in a virtual machine created with QEMU/KVM. In watching the verbose output at startup I think I can see that the "network services" service fails to startup (red) but its hard to tell. I also have a new netplan config.yaml file: network: I was not able to get the bridge to instantiate via netplan, but it seems to work if I create it beforehand manually using "ip link": sudo ip link add br0 type bridgeĮxecStart=/bin/bash /home//Scripts/netplanApply.sh I've solved this issue for now by creating a startup script. The result is the netplan implemented bridge disappearing and the kvm virtual interface and bridge appearing as shown in img 4 above, and netplan able to be applied but no visible changes made, and all routes lost. Just FYI I've tried with a reinstall and different order of installation, successfully creating and addressing the bridge on nic#2, and then installing qemu-kvm and libvirt. Why did the routes disappear when I applied the netplan?Īm I doing this correctly? Or does anyone know of any current issues with creating/managing network interfaces and ip routes between QEMU-KVM, libvirt, and netplan? Looking back at the interfaces status, it looks like they have a working link layer, just no working routes. The routes have all disappeared except for the route to the virtual bridge. I look at the network interfaces and see this:Įxisting IP addresses all lost. ![]() It compiles successfully via sudo netplan generate, and is applied "successfully" via sudo netplan try, entering to confirm, but then. Next I edit the netplan config file in /etc/netplan/. ![]() This adds a virtual bridge and virtual interface to the system: I install qemu-kvm, libvirt-daemon-system, libvirt-clients, etc, successfully. It looks like they break each others network configs to me, but I wanted to put this question out to see if I'm perhaps just not using them correctly.Īfter installing ubuntu server 20.04.3 LTS my network interfaces and routes look like this (via "ip route"): The basic problem is that I cannot get qemu-kvm, libvirt and netplan working together. Also I am still somewhat of a linux and routing novice so forgive my ignorance. Very new stack exchange user here, so apologies in advance if I am breaking protocol in any way. ![]()
