OpenPOWER Host OS builds repository

Build the best of OpenPOWER platform virtualization

Considering the speed of the development of new features, or even Hardware is created in the OpenPOWER ecosystem, it's a challenge to get them in the traditional stable GNU/Linux distribution scenario.

open-power-host-os/builds repository is an open source collaboration effort that aims to help administrators to build and deploy the latest and greatest capabilities in the OpenPOWER world through a build script that provides software well packaged and designed for the Supported GNU/Linux distributions

Supported GNU/Linux distributions

• CentOS 7.2 PPC64LE

Installation

RPM Based distributions

• Install epel repository (Extra Packages for Enterprise Linux):

# sudo yum install --downloadonly --downloaddir=. epel-release
# sudo yum localinstall epel-release-7-5.noarch.rpm # Note the version may change.

• Install

• mock
• PyYAML
• git
• python-pygit2
• svn
• bzip2

# sudo yum install -y mock PyYAML git python-pygit2 svn bzip2

Settings

• Disable SMT

# sudo ppc64_cpu --smt=off

• Setup environment and user

# sudo python setup_environment.py LOGIN

Naturally, you need to replace LOGIN by the user name you'll use to run host-os-build.py, which should not run using root user, even if that user doesn't exists yet.

Running

• Build a single package

# python host-os-build.py --package libvirt

• Build all software

# python host-os-build.py --verbose

Note the --verbose parameter to get all the log messages in the console. Instead of the standard ordinary messages. Please see --help for more options.

# python host-os-build.py --help

Using the RPMs

We decided that's is a little bit intrusive to install all the produced RPMs since some of them may not fit your needs. At the end of the process you'll see a new results directory inside this project's root.

A suggested set of packages tested is the following:

• kernel
• qemu
• qemu-kvm-tools
• qemu-system-ppc
• qemu-guest-agent
• qemu-system-x86
• qemu-kvm
• qemu-debuginfo
• qemu-common
• qemu-img
• libseccomp
• libvirt-daemon-kvm
• libvirt-lock-sanlock
• libvirt-docs
• libvirt-daemon-driver-nodedev
• libvirt-daemon-driver-interface
• libvirt-daemon-driver-network
• libvirt-daemon-qemu
• libvirt
• libvirt-nss
• libvirt-devel
• libvirt-debuginfo
• libvirt-client
• libvirt-daemon-driver-nwfilter
• libvirt-daemon-driver-secret
• libvirt-daemon-driver-qemu
• libvirt-daemon-config-network
• libvirt-daemon-lxc
• libvirt-login-shell
• libvirt-daemon
• libvirt-daemon-config-nwfilter
• libvirt-daemon-driver-storage
• libvirt-daemon-driver-lxc
• SLOF

You can use the following command to install, for instance, libseccomp's RPM:

# sudo yum localinstall result/libseccomp-2.3.1-0.el7.centos.1.ppc64le.rpm

Note that some of those packages are debuginfo which are recommended in order to provide useful information for bugs in the case of any failures.

Also no version is informed on the list above to make it valid even for future versions with minor version changes.

Validating

There is a whole repository dedicated to testing available at https://github.com/open-power-host-os/tests
