Bug 324589 – openvswitch new package

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Etaoin Shrdlu 2010-06-18 12:23:16 UTC]

If would be great to have an ebuild for openvswitch (http://openvswitch.org/) in portage. Quite cool and supports the most popular virtualization technologies.

Reproducible: Always

[Comment 1 Michael Weber (RETIRED) 2010-06-22 09:19:30 UTC]

Hello, The Gentoo Team would like to firstly thank you for your ebuild 
submission. We also apologize for not being able to accommodate you in a timely
manner. There are simply too many new packages.

Allow me to use this opportunity to introduce you to Gentoo Sunrise. The 
sunrise overlay[1] is a overlay for Gentoo which we allow trusted users to 
commit to and all users can have ebuilds reviewed by Gentoo devs for entry 
into the overlay. So, the sunrise team is suggesting that you look into this 
and submit your ebuild to the overlay where even *you* can commit to. =)

Thanks,
On behalf of the Gentoo Sunrise Team,
Michael.

Would be nice if someone with more ebuild experience could review this

[Comment 10 Tiziano Müller (RETIRED) 2011-12-18 20:50:37 UTC]

as a side-node: I've added the init.d-scripts to my version of the ebuild in my dev-overlay. I hope I can look at them again and then move the ebuild to the tree.

[Comment 11 Florian Manschwetus 2011-12-18 21:13:56 UTC]

The ebuild works fine by renaming for 1.3.0 => just bumpp

I'm currently working on patches for xen adding openvswitch support, I'll attach them tomorrow, they are working most of the way, just rmeoving the hvm-qemu tap interfaces fails for some reason, maybe I have time to dig into it (hint have a look for epatch_user to add this in a comfortable way). Additionally I started adding kernel-3.3 support, it works but I guess I somehow missusing the linux_info eclass

If I get it tomorrow. I'll merge my stuff with yours, to get to a common base.

Added patched ebuild based on your work.

Changes:
* use python eclass and depend on python:2 since parts of openvswitch are not yet compatible to python:3
* add tcpdump as configurable runtime dependency (see README)
* add support for brcompat module (bridge compatibility layer) and related init script
* changed socket path from /var/lib/run/openvswitch to /var/run/openvswitch

Works fine with Xen 4.1.2 and vanilla kernel 3.2.5.

Ebuilds for openvswitch [1] and xen-tools [2] can be found in our little overlay. I should have filed bugs, I know...

Nice work, thx. I'll try to get a complete round up including the work of Tiziano tomorrow. Afterwards I'll cleanup the bug and provide also a new live ebuild. Hope now this hits tree fast as ovs has become a vanilla feature ;)

[Comment 21 Florian Manschwetus 2012-03-20 22:08:41 UTC]

Have had a short look at Peters xen-tools patches, really interesting, I modified existing scripts adding autodetection for ovs / brctl

[Comment 22 Keith Amidon 2012-05-25 22:37:29 UTC]

I'm running OVS on a laptop providing networking to some KVM VMs.  Occasionally, when the laptop is heavily loaded, networking performance will suffer excessively.  I believe this is due to the ovs-vswitchd being involved in flow setup and being starved for CPU.  I've been running with a tweaked version of the openvswitch-1.4.0-r2.ebuild attached here that is been revbumped to version 1.4.1 (which was released May 2nd) and which adds the following to /etc/conf.d/ovs-vswitchd.conf:

# The ovs-vswitchd process is involved in new flow creation.  If it
# is starved by other processes then networking will suffer which may
# further affect overall system performance.  Running ovs-vswitchd at
# a higher priority can mitigate this impact.
NICE_LEVEL=-10

and the following change to start() in /etc/init.d/ovs-vswitchd.conf:

start() {
	ebegin "Starting Open vSwitch daemon"
	start-stop-daemon --nice ${NICE_LEVEL} --start --quiet --exec /usr/sbin/ovs-vswitchd -- --pidfile --detach ${DB_SOCKET}
	eend ${?}
}

This setup seems to have resolved the issues I was experiencing.  It would be great if these changes could be incorporated into the consolidated ebuild that is in the works.

[Comment 23 Tiziano Müller (RETIRED) 2012-06-27 08:50:26 UTC]

Version 1.6.1 (for kernel 3.3+) is now in the tree.
Thanks everyone.
