Welcome to the Vdsm source repository.
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.
This repository is hosted on gerrit.ovirt.org:vdsm and a backup of it is hosted on GitHub:vdsm
Patches are welcome!
Please submit patches to gerrit.ovirt.org:vdsm. If you are not familiar with the review process for Gerrit patches you can read about Working with oVirt Gerrit on the oVirt website.
NOTE: We might not notice pull requests that you create on Github, because we only use Github for backups.
To submit a bug or suggest an enhancement for Vdsm please use oVirt Bugzilla for vdsm product.
If you find a documentation issue on the oVirt website please navigate and click "Report an issue on GitHub" in the page footer.
Add ovirt repositories to your repositories list:
sudo dnf install -y http://resources.ovirt.org/pub/yum-repo/ovirt-release-master.rpm
Install Vdsm:
sudo dnf 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).
Set local git clone:
sudo dnf install -y git
git clone "https://gerrit.ovirt.org/vdsm"
Install additional packages for Fedora, CentOS, and RHEL:
sudo dnf install -y `cat automation/check-patch.packages`
Create virtual environment for vdsm:
python3 -m venv ~/.venv/vdsm
source ~/.venv/vdsm/bin/activate
pip install --upgrade pip
pip install -r docker/requirements.txt
deactivate
Before running vdsm tests, activate the environment:
source ~/.venv/vdsm/bin/activate
When done, you can deactivate the environment:
deactivate
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 dnf upgrade */vdsm*.rpm)
Release process of Vdsm version VERSION consists of the following
steps:
-
Changing
Version:field value invdsm.spec.intoVERSION. -
Updating
%changelogline invdsm.spec.into the current date, the committer, andVERSION. -
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.
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.
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.
There are two mailing lists for discussions:
-
For technical discussions about the project and its code base.
-
For questions by users, who do not want to be swamped by technicalities.
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
