Re: [Openstack] Host OS CentOS 6.4 or Ubuntu 12.04
Hello, Samuel Winchenbach wrote as an answer to Haitao Jiang: I agree with Logan that it is personal preference. ... I am sure for every complaint I have about Ubuntu someone has an equal complaint about CentOS. Samuel is right. Here is an example for such a complaint: Two or three months ago I had system freezes on a particular hardware with CentOS 6.4 with the original 2.6.32 kernel package shipped with CentOS 6.4. These same systems are now running stable for at least two months with kernel 3.6.6-1.el6.elrepo.x86_64 Having used several distributions (Slackware, SuSE, Red Hat, Debian, Ubuntu, CentOS to name a few) since 1994 here and at customers all over the world my advice is: Try a particular distribution and version on your particular hardware for at least 2 weeks. Put heavy load on disks, cpus, memory and network during this period. If it doesn't freeze or otherwise shows bad behaviour stay with this distribution. Otherwise try to fix it or pick another distro and start over. If this doesn't succeed either try to find the cause (depending on your time and skills available to do so) or toss the hardware and start over again. And this advice has absolutely nothing to do with OpenStack. Sorry: I simply couldn't resist.

Re: [Openstack] Host OS CentOS 6.4 or Ubuntu 12.04
Honestly a lot of it has to do with personal preference, or what your organization is comfortable with. As far as guests go, CentOS has no official guest images (qcow2/raw). Ubuntu has very good official images. So does Red Hat but those aren't free. As far as ease to deploy, Ubuntu's recommend strategy is using MAAS/Juju. Red hat recently released RDO (openstack.red hat.com), which uses an installer called Packstack. You'll just need to research those options and pick one. Another good option for CentOS deployment is Mirantis' Fuel ( fuel.mirantis.com). Currently Fuel only supports CentOS/RHEL but they say Ubuntu support is coming.

For examples, like Python version. Ubuntu also seems has more community support etc. But at the same time, Redhat is rank as one of contributors to the OpenStack code base.

Re: [Openstack] Host OS CentOS 6.4 or Ubuntu 12.04
I agree with Logan that it is personal preference. I will give you my opinion: I created a 4 node cluster using Ubuntu and if I had to do it again I would use CentOS. I find CentOS configuration much more consistent; Ubuntu uses a combination of Upstart and rc scripts which can be quite a nightmare when you need things to startup and shutdown in a certain order. Ubuntu tends to have much more frequent package (including kernels!) updates which may be good for certain use-cases but I find it tedious to maintain. I am sure for every complaint I have about Ubuntu someone has an equal complaint about CentOS. - Sam On Fri, Jul 12, 2013 at 1:59 PM, Logan McNaughton lo...@bacoosta.comwrote: Honestly a lot of it has to do with personal preference, or what your organization is comfortable with.
