Vdsm: Virtual Desktop Server Manager

The Vdsm service exposes an API for managing virtualization hosts running the KVM hypervisor technology. Vdsm manages and monitors the host's storage, memory and networks as well as virtual machine creation, other host administration tasks, statistics gathering, and log collection.

Manual installation

Add ovirt repositories to your repositories list:

sudo yum install -y http://resources.ovirt.org/pub/yum-repo/ovirt-release-master.rpm

Install Vdsm:

sudo yum install vdsm vdsm-client

Configure Vdsm:

sudo vdsm-tool configure --force

--force flag will override old conf files with vdsm defaults and restart services that were configured (if were already running).

Enable and start Vdsm service:

sudo systemctl enable --now vdsmd

To inspect Vdsm service status:

sudo systemctl status vdsmd

Vdsm logs can be found at /var/log/vdsm/*.log (refer to README.logging for further information).

Development environment setup

Set local git clone:

sudo yum install -y git
git clone http://gerrit.ovirt.org/p/vdsm.git .

Install additional packages for Fedora:

sudo dnf install -y `cat automation/check-patch.packages.fc30`

Install additional packages for CentOS:

sudo yum install -y `cat automation/check-patch.packages.el8`
easy_install pip

Install tox:

pip install --user tox

Building Vdsm

To configure sources (run ./configure --help to see configuration options):

git clean -xfd
./autogen.sh --system --enable-timestamp
make

To test Vdsm (refer to tests/README for further tests information):

make check

To create an RPM:

rm -rf ~/rpmbuild/RPMS/*/vdsm*.rpm
make rpm

To update your system with local build's RPM:

(cd ~/rpmbuild/RPMS && sudo yum upgrade */vdsm*.rpm)

Making new releases

Release process of Vdsm version VERSION consists of the following steps:

• Changing Version: field value in vdsm.spec.in to VERSION.

• Updating %changelog line in vdsm.spec.in to the current date, the committer, and VERSION.

• Committing these changes, with subject "New release: VERSION" and posting the patch to gerrit.

• Verifying the patch by checking that the Jenkins build produced a correct set of rpm's with the correct version.

• Merging the patch (no review needed).

• Tagging the commit immediately after merge with an annotated tag: git tag -a vVERSION

• Setting "Keep this build forever" for the check-merge Jenkins build.

• Updating releng-tools with the new Vdsm version. See releng-tools repo (git clone https://gerrit.ovirt.org/releng-tools) and Vdsm related patches there for examples.

CI

Running tests locally is convenient, but before your changes can be merged, we need to test them on all supported distributions and architectures.

When you submit patches to gerrit, oVirt's Jenkins CI will run its tests according to configuration in the stdci.yaml file.

Travis CI for storage patches

oVirt's Jenkins CI is the integrated method for testing Vdsm patches, however for storage related patches we have to cover also 4k tests which are not covered currently by Jenkins CI. This can be achieved in a fast way manually and independently from gerrit by invoking Travis CI on your github branch:

• Fork the project on github.
• Visit https://travis-ci.org, register using your github account, and enable builds for your Vdsm fork.
• Push your changes to your github fork to trigger a build.

See .travis.yml file for tested Travis platforms and tests configurations.

Getting Help

There are two mailing lists for discussions:

• For technical discussions about the project and its code base.

  http://lists.ovirt.org/mailman/listinfo/devel

• For questions by users, who do not want to be swamped by technicalities.

  http://lists.ovirt.org/mailman/listinfo/users

The developers also hang out on IRC at #vdsm hosted on freenode.net

The latest upstream code can be obtained from GIT:

git clone https://gerrit.ovirt.org/vdsm
