Hi guys, I should lurk a bit longer before asking, but I''m getting a bit frustrated. it seems that centos 6/red hat6 is working on getting away from xen, but at this point it''s still my preferred hypervisor. I found a tutorial at: http://wiki.xen.org/xenwiki/RHEL6Xen4Tutorial that suggests it might be workable for centos 6, but when I get to the point of installing a dom0 capable kernel, I seem to hit a wall with git clone git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git linux-2.6-xen errors out with Initialized empty Git repository in /root/kernel/xen/.git/ fatal: Unable to look up git.kernel.org (port 9418) (Name or service not known) although ping works and telnet to that host on 9418 seems to get somewhere.(after some gyrations). does anyone have an easier way to do this or another suggestion for getting this version of the kernel? thanks. -- Even the Magic 8 ball has an opinion on email clients: Outlook not so good. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

The release kernel is (and will remain) 2.6.32 for the life of EL6. In that version, Xen (and other popular tools) were not in the mainline, so providing support for Xen would mean a fairly heavy investment in maintaining a large patch set. From what I gather, I''d wager we''ll see Xen back in RHEL for version 7. In the mean time, I know that many are working on adding external support for Xen in EL6. I''m not sure what the current state is, but I do believe the most recent focus has been restoring dom0 support for the Fedora 16 release. Once that is finalized, I''d not be surprised to see the attention return to getting working RPMs for EL6 in CentOS. These are, of course, my opinions and guesses only. :) -- Digimer E-Mail: digimer@alteeve.com Freenode handle: digimer Papers and Projects: http://alteeve.com Node Assassin: http://nodeassassin.org "At what point did we forget that the Space Shuttle was, essentially, a program that strapped human beings to an explosion and tried to stab through the sky with fire and math?" _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

In that case I would be surprised to see Xen ever returning to RHEL (unless they decide to drop KVM in the future for whatever reasons). Am I missing something here?

Simple business math. I really don''t think there was any animosity in the decision, and I don''t see why they wouldn''t restore support if it can be done within a fair budget and there is sufficient demand (as I suspect there is). In the end though, this is my conjecture only based on watching the two hypervisors over the last couple of years. -- Digimer E-Mail: digimer@alteeve.com Freenode handle: digimer Papers and Projects: http://alteeve.com Node Assassin: http://nodeassassin.org "At what point did we forget that the Space Shuttle was, essentially, a program that strapped human beings to an explosion and tried to stab through the sky with fire and math?" _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

A distributor would have to go through extra work to remove it. This is why RHEL will more than likely have it.
