Cockpit-oVirt plugin

Virtual Machine Management plugin for Cockpit based on oVirt.

Features in recent release:

• list of VMs running on a host

• single VM detail

• VM monitoring (statistics and usage charts)

• basic VM operations

• edit of vdsm.conf

• plugin's components are embeddable to other tools/dashboard, like VM detail

• With optional Engine login available

  • list of VMs administered by the oVirt Engine in a cluster
  • VM details

The plugin requires Virtual Desktop Server Manager VDSM, part of the oVirt project.

With optional oVirt Engine installed, the plugin allows basic monitoring/management of VMs administered by the engine beyond the scope of the single host running the cockpit.

Install From Sources

Build

For build you will need Node.js v4 (LTS). If your OS repositories don't contain required version you can always use Node Version Manager nvm to install and manage multiple Node.js versions side by side.

Run npm i to install dependencies.

Use npm t to run tests and lint the code.

Use npm run build to create production build.

The last command will generate /dist directory containing all files that are needed to be copied to your cockpit installation.

Developer's note: you can use npm run dev to start a background build service that will incrementally recompile the code on the fly and update the contents of /dist directory. Symbolically linking the /dist directory into proper place (see below) one can achieve automatic code updates in running cockpit instance.

Deploy Plugin

• after build, copy contents of /dist to /root/.local/share/cockpit/ovirt/

• Alternative:

  • copy contents of /dist to /usr/share/cockpit/ovirt/
  • change VDSM variable in ovirt.js to new location of vdsm/vdsm shell script

• Troubleshooting tips:

  • Installation instructions stated above should lead to successful setup on Centos 7. If not, following tips might help:

    • If VDSM is properly configured, following command should return without any error:

      # /root/.local/share/cockpit/ovirt/vdsm/vdsm getAllVmStats

  • As the plugin is in early development state, PLEASE let author know about all issues you encounter during installation/use, it will help in making the product better.
