vmango

Vmango is a virtual machines management web interface written using Go.

The main goal of project is not to provide a hypervisor configuration tool, because that problem already solved by many configuration management systems like Ansible or Puppet, but provide a convenient way to manage virtual machines on existing hypervisors.

Current features:

• SSH keys management and injection
• Volume management
• KVM machines via libvirt
• Web console
• Support for cloud OS images (with cloud-init installed)
• Custom userdata for cloud-init
• Bridged network

Installation

There are two RPM repositories:

• vmango for the latest tagged release, it may be considered stable
• vmango-devel contains packages built automatically from the latest commit in master branch

CentOS 7 and 8

1. Enable copr reposotory, use subuk/vmango-devel for the latest version, subuk/vmango for stable
2. Install package
3. Edit configuration file /etc/vmango.conf
4. Start and enable systemd service vmango

yum install -y yum-plugin-copr && yum copr -y enable subuk/vmango
yum install -y vmango
systemctl enable --now vmango

Ubuntu 18.04

1. Follow instructions on vmango or vmango-devel ppa page https://launchpad.net/~subuk/+archive/ubuntu/vmango
2. Install package
3. Edit configuration file /etc/vmango.conf

sudo add-apt-repository ppa:subuk/vmango
sudo apt-get install vmango

Hypervisor configuration

Install libvirt and qemu-kvm.

Ubuntu:

sudo apt-get install libvirt-bin qemu-kvm qemu-system

Centos:

yum install -y libvirt qemu-kvm
systemctl enable --now libvirtd

Allow your user to access libvirt socket:

sudo usermod -aG libvirtd [username]
newgrp libvirtd

Download vm images to default libvirt pool location:

cd /var/lib/libvirt/images/
wget https://cloud.centos.org/centos/7/images/CentOS-7-x86_64-GenericCloud-1901.qcow2
wget https://cloud-images.ubuntu.com/minimal/releases/bionic/release/ubuntu-18.04-minimal-cloudimg-amd64.img

Define default volume pool (if not exists) and start it:

virsh pool-define-as default dir --target /var/lib/libvirt/images/
virsh pool-start default
virsh pool-autostart default

Local run

Copy vmango.dist.conf to vmango.conf and change configuration if needed.

Run app

make && ./bin/vmango web

View it on http://localhost:8080 (login with admin / admin by default)

Dependencies for Ubuntu 14.04+

Install libvirt and kvm

sudo apt-get install libvirt-dev libvirt-bin qemu-kvm qemu-system genisoimage

Install Go compiler. Configure libvirt as described above. Now you can use your own computer as hypervisor.

Dependencies for MacOS

Install Go compiler, libvirt C library and mkisofs util (for configdrive creation)

brew install go
brew install libvirt
brew install dvdrtools

You need a linux hypervisor somewhere in the world, because libvirt doesn't support MacOS. Make sure to add ?socket option to remote libvirt urls.
