Hi Everyone, We currently run CentOS 5.8 (With the CentOS stock kernel) and use Xen 3.4.x (and associated packages) from GitCo. This has been a rock solid combination for us. However, we need to think about the future, and wish to move to Xen 4.2. From my searching, I can''t seem to find an easy way to install Xen 4.2. Are there any *trustworthy* third party repos out there that can provide Xen 4.2.x as well as a good, regularly updated solid kernel that would work on CentOS6? I''ve come across the choon repos (which does provide Xen 4.2.x and kernel), however I''d like to hear the list''s opinion on the trustworthiness of this repo before I deploy it on our production servers :) I appreciate everyone time Thanks

You can''t find any 4.2 packages or the like through standard channels because 4.2 is still "unstable" (e.g., under development); for the most part, you''re expected to be building it yourself if you want to play with it. For that reason, I would advise against production deployment for the time being. I would still strongly suggest trying out 4.2 in the meantime, out of production, since it''s feature complete (or was supposed to be, starting in April). I believe the timeline was set to have RCs by now, but I haven''t been keeping up with it. As for the repos you''ve found, I''d trust them for testing, but as a comment on the code base itself, any repos at present will be unsuitable for production use until the devs feel confident enough to give it their blessing as a stable release.

I''m about 95% certain that the past couple Ubuntu releases offer Xen support - unfortunately, not on a machine where i can fire up aptitude and check On Friday, June 15, 2012, Jonathan Tripathy wrote:> > On 15/06/2012 11:41, John Sherwood wrote: > >> You can''t find any 4.2 packages or the like through standard channels >> because 4.2 is still "unstable" (e.g., under development); for the most >> part, you''re expected to be building it yourself if you want to play with >> it.

Ubuntu does indeed seem to offer 4.1!! http://packages.ubuntu.com/precise/xen-hypervisor-4.1-amd64 This means that the Xen page on the Ubuntu website is wrong!! https://help.ubuntu.com/community/Xen "Ubuntu 10.04 does not come with Xen binaries so you will have to manually download and compile Xen along with a kernel that is suitable to work with Xen" I just assumed that future version didn''t, but clearly they do.

I guess the main reason I wish to upgrade is due to the recent security CVEs announced, and one day 3.4.x will not get any more security updates :( We don''t use tap:aio, only phy, so I guess the blktap issue doesn''t affect us?

KVM is just their default at the moment, and therefore the focus of their own developers. So more of the burden of making sure things work falls on the Xen community. Relationships with distros has been a weak point of xen.org in the past; but we''re trying to address that going forward. -George _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users

So then, going forward, you recommend that we switch to Ubuntu+Xen (using Ubuntu Universe repo) if we want to use 4.1.x? As a company, we have plenty of experience with Ubuntu, so that''s not an issue. I''m specially talking about the Xen aspects here.

There is security flaw but beside RHEL we dont see response on other vendors yet. Is xen.org official tarbal updated yet? Both gitco.de and choon.net - there is no update yet. Even alpinelinux.org which I am very interested in has no xen hypervisor update yet. Another Xen 4.1.2 repo http://www.crc.id.au/xen-on-rhel6-scientific-linux-6-centos-6-howto/ is not updated too. I don have Xenserver by citrix - is their product updated? For 4.1.2 seems like only viable options are Debian Squeezy and Ubuntu 12.04 right now.

I think most downstream vendors (with the exception of RHEL), tend to track xenbits ultimately. The patch was only released on Tuesday. Of course, RHEL do their own thing due to their commercial product.

What can I say from my point of view: 1. PV DomU works out of the box, I had not any issues with it 2. To start HVM DomU I had to fix some symbolic links. I think that won''t an issue for you, you will find info in xen logs about missing files when you will try to start HVM DomU. AFAIR couple of files were renamed in ubuntu packages i. e. xen -> xen-precise and this made an issue. In HVM DomU running Ubuntu 10.04/12.04 I found significant drops in perfomance when network interface under high load, so after tests I did not use HVM at all. Since 11.10 Ubuntu supports PV+HVM mode in xen, so I switched HVM machines to PV+HVM and issues with perfomance have gone away. I don''t remember exactly, in HVM or PV+HVM, but I had to create network interface manually, otherwise it could not work with xen bridge. Also, I could not resolve an issue with ubuntu DomU screen resolution in HVM/PV+HVM mode. Maximal resolution I could manage to 1024x768. I posted bug at the launchpad, but I think it won''t be fixed in near future. And I did not try to run windows in DomU, so don''t know how it will work. 3. I could not enable iommu nor verbose mode for iommu. Don''t know is that a bug in Ubuntu packages or bug in xen, no one could tell me why verbose mode for iommu did not work. Sergey Zhukov

But in HVM/PV+HVM such config did not work, I tried to point vif to all of existing Dom0 interfaces, but bridging had still not worked, (I could only get NAT over some of the interfaces).

If my memory serves me correctly, discussions here on the list seem to say that the stock RHEL kernel doesn''t work very well with Xen 4.x The only testing I did was to run some Xen 4.x with Centos 5.x with PV DomUs in a VMWare ESXi VM.

The last time, this was discussed there were still a couple of loose ends on this page.

All security related I take it seriously and release packages accordingly mostly within 24 hours after testing. Read http://choonrpms.blogspot.com/ for more information. Xen v4.0, v4.1 and even v4.2 (xen-unstable) are released accordingly: v4.0 - http://choonrpms.blogspot.com/2012/06/xen-404-215920-release.html v4.1 - http://choonrpms.blogspot.com/2012/06/xen-413-233010-release.html v4.2 - http://choonrpms.blogspot.com/2012/06/xen-420-254810-release.html In fact, I update often for xen related packages. I don''t update such information in my forum since I mentioned that I will post updates in http://choonrpms.blogspot.com/ since 09 Mar 2012 SGT/GMT+8. Hopefully this will clear any confusion or doubts. Thanks.

Hello Giam Teck Choon thank you very much for your answer. You are doing great work with your repo! I was wrong with the info that your repo isnt updated yet. Now I seed that your repo is greatly maintained. Was looking for info only at your blog. Sorry for that!

I will be using Ubuntu as my main test environment, and we''re hoping to get regular Ubuntu virt test days going as well. -George
