Xen project Mailing List

Hi,

At Ravello/Oracle, we would be interested with contributing patches to the Xen hypervisor, especially in areas related , and our team have no experience with Xen.

I've read the contributor guideline, and I think that before contributing big patches, we should start with contributing small patches, to make sure we're fluent with the entire contribution process, e.g., coverity static analysis.

As of the setup phase. I created a pbuilder clean environment with the following script, note the list of build dependencies:

#!/bin/bash -vx

set -e

sudo apt install pbuilder

[ ! -f /var/cache/pbuilder/base.tgz ] && sudo pbuilder --create --distribution xenial --othermirror 'deb http://il.archive.ubuntu.com/ubuntu/ xenial main restricted universe multiverse'

DEPS=/tmp/$USER-$$-dep-install

echo -e '#!/bin/bash -xv\napt-get install -y wget curl ftp autotools-dev debhelper dpkg-dev lsb-release python-dev bcc gcc-multilib e2fslibs-dev iasl seabios libaio-dev libfdt-dev libglib2.0-dev liblzma-dev libncurses5-dev libpixman-1-dev libyajl-dev libssl-dev pkg-config uuid-dev zlib1g-dev libsystemd-dev texinfo fakeroot' > $DEPS

trap "rm $DEPS" EXIT

chmod +x $DEPS

sudo pbuilder --execute --save-after-exec $DEPS

Then I went on, pbuilder --login, and inside

$ make debball

I ran a plain Ubuntu Server on KVM with nested virtualization enabled, then I installed the deb on the ubuntu,

$ update-grub

installed some runtime dependencies

$ apt install libpixman-1-dev libfdt-dev libaio-dev libyajl-dev

and booted with the new Xen entry. Note that you can rename

/etc/grub.d/20_linux_xen to be /etc/grub.d/09_linux_xen before update-grub

and hence have your machine to boot to Xen by default.

Finally I started the xen daemons

$ service xen-watchdog start

$ service xendomains start

$ service xendriverdomain start

$ service xencommons start

Than, I created VMs with the xl create tool.

I'm not sure I have the best setup, and I'll be happy to hear what I did wrong, or what could be improved.

Thanks!

Elazar,

we do have a list of links to starter projects at the bottom of https://wiki.xenproject.org/wiki/Outreachy/Round12%2B2016GSoC, but these are probably not quite what you are looking for. We don't maintain a list of starter bugs, because much of it depends on what you want to get out of it. I am assuming you solved build, set-up, etc. already?

If you could give us a bit of context and what you are trying to accomplish, I can CC a community member who can then point you in the right direction or alternatively can come up with a small project that can help you get up to speed.

Regards
Lars

Hi,
For someone wishing to start contributing to Xen hypervisor, what would you recommend as an easy, educational, bug he could start with?

Thanks,
