libvirt-go Build Status GoDoc

Go bindings for libvirt.

Make sure to have libvirt-dev package (or the development files otherwise somewhere in your include path)

Version Support

The libvirt go package provides API coverage for libvirt versions from 1.2.0 onwards, through conditional compilation of newer APIs.



The libvirt project aims to add support for new APIs to libvirt-go as soon as they are added to the main libvirt C library. If you are submitting changes to the libvirt C library API, please submit a libvirt-go change at the same time.

Bug fixes and other improvements to the libvirt-go library are welcome at any time. The preferred submission method is to use git send-email to submit patches to the libvir-list@redhat.com mailing list. eg. to send a single patch

git send-email --to libvir-list@redhat.com --subject-prefix "PATCH go" \ --smtp-server=$HOSTNAME -1

Or to send all patches on the current branch, against master

git send-email --to libvir-list@redhat.com --subject-prefix "PATCH go" \ --smtp-server=$HOSTNAME --no-chain-reply-to --cover-letter --annotate \ master..

Note the master GIT repository is at

The following automatic read-only mirrors are available as a convenience to allow contributors to "fork" the repository:

While you can send pull-requests to these mirrors, they will be re-submitted via emai to the mailing list for review before being merged, unless they are trivial/obvious bug fixes.


The core API unit tests are all written to use the built-in test driver (test:///default), so they have no interaction with the host OS environment.

Coverage of libvirt C library APIs / constants is verified using automated tests. These can be run by passing the 'api' build tag. eg go test -tags api

For areas where the test driver lacks functionality, it is possible to use the QEMU or LXC drivers to exercise code. Such tests must be part of the 'integration_test.go' file though, which is only run when passing the 'integration' build tag. eg go test -tags integration

In order to run the unit tests, libvirtd should be configured to allow your user account read-write access with no passwords. This can be easily done using polkit config files

# cat > /etc/polkit-1/localauthority/50-local.d/50-libvirt.pkla  <<EOF
[Passwordless libvirt access]

(Replace 'berrange' with your UNIX user name).

One of the integration tests also requires that libvirtd is listening for TCP connections on localhost, with sasl auth This can be setup by editing /etc/libvirt/libvirtd.conf to set


and then start libvirtd with the --listen flag (this can be set in /etc/sysconfig/libvirtd to make it persistent).

Then create a sasl user

   saslpasswd2 -a libvirt user

and enter "pass" as the password.

Alternatively a Vagrantfile, requiring use of virtualbox, is included to run the integration tests:

  • cd ./vagrant
  • vagrant up to provision the virtual machine
  • vagrant ssh to login to the virtual machine

Once inside, sudo su - and go test -tags integration libvirt.
