virt 0.2.11

Rust bindings to the libvirt C library

This crate provides a Rust bindings to the libvirt C library

The bindings try to be a direct mapping of the underling C API with some differences to match Rust conventions.

Important considerations

Make sure the libvirt-dev or libvirt-devel package is installed (or that the development files are in your include path).

The bindings do not implement all of what the C library is providing but we do consider the current API quite stable.

The bindings use standard errors handling from Rust. Each method (there are some exceptions) returns a type Option or Result.



CI is executing tests automatically from libvirt 2.5.0 to 5.5.0. Using Rust from stable, beta to nightly.

To execute locally tests and other excerices

cargo test --verbose

Integration tests use a real connection to libvirtd. For instance uses a qemu:///system connection. They are all ignored by default.

cargo test --verbose -- --ignored

Similar to libvirt-go, the integration tests also require that libvirtd listens on localhost with sasl auth. This can be setup by editing /etc/libvirt/libvirtd.conf as follows:


and starting 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.

To run examples

# cargo run --example hello
# cargo run --example migrate -- qemu:///system tcp+qemu:// myguest


The libvirt project aims to add support for new APIs to libvirt-rs 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-rs change at the same time.

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

   git send-email --to --cc \
       --subject-prefix "PATCH Rust" --smtp-server=$HOSTNAME -1

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

   git send-email --to --cc \
       --subject-prefix "PATCH Rust" --smtp-server=$HOSTNAME --no-chain-reply-to \
       --cover-letter --annotate master..

It is also possible to use git-publish.

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 email to the mailing list for review before being merged, unless they are trivial/obvious bug fixes.
