It might be an interesting experiment, But one that is very unlikely to succeed. RHEL 5/CentOS 5 are based on FC6. The OP said he was running F8. This would be a downgrade in terms of package versions. Because CentOS packages always have higher version numbers than the corresponding RHEL packages, converting from RHEL5 to CentOS is trivial. Downgrading a system without reinstalling is not.

Yeah, older virt-install doesn't know to look in the "images-xen" stanza in the ".treeinfo" file to determine which images to use: https://bugzilla.redhat.com/460585 Cole has been backporting the patches and 5.3 should be able to be able to install Fedora 10.

I am concerned that we might be left with a period of time where there won't be any supported Redhat or Fedora platform to run Xen guests, and of course the lack of current support in RHEL is reducing the testing that Fedora 10 xen is getting.

I was surprised just how poorly it works. My experiences with paravirt Xen have been: - Fine performance, as long as "normal" file I/O is being used. - Bad performance for "low-level" operations like file system creation This was with "raw device" based virtual disks.

I think it is a bad idea to push major new versions of anything to a distro that is about to go end of life. We've only just released these new libvirt, virt-manager & virtinst packages. We *will* cause regressions in functionality in F8, and with it about to go end of life, we'll be unable to push further updates to fix the regressions. If someone really badly wants new libvirt/virt-manager for F8, then they can easily just take the new RPMs from F9/10 and do a rpmbuild --rebuild on the src. This avoids causing regressions for anyone else on F8 who don't care.

The other solution is to build the package in Testing and not push it to Stable, like I did for libvirt, I think this minimize the risks while avoiding the multiple builds (and hence risk of massive divergence of the versions).

Fedora 8 is for now the latest Fedora distribution with a Xen dom0 : * Fedora 9 doesn't have a dom0 according to http://fedoraproject.org/wiki/Features/XenPvops#Release_Notes * the next Fedora with a Xen dom0 will be Fedora 10, according to http://docs.fedoraproject.org/release-notes/f9/en_US/sn-Virtualization.html (20.1 Kernel Integration Improvements : "Xen Dom0 support will be added back in Fedora 10") I am curious about : > The other solution is to build the package in Testing and not push it > to Stable, like I did for libvirt, I think this minimize the risks while > avoiding the multiple builds (and hence risk of massive divergence of > the versions). Does the fact of pushing Fedora 8 packages into Testing instead of Stable allows future updates of theses packages to be available to Fedora 8 users even after its end of life ?

Fedora will not get Xen host supoport again until its merged upstream, which is 2.6.28 best case, possibly longer. > > The other solution is to build the package in Testing and not push it > >to Stable, like I did for libvirt, I think this minimize the risks while > >avoiding the multiple builds (and hence risk of massive divergence of > >the versions). > Does the fact of pushing Fedora 8 packages into Testing instead of Stable > allows future updates of theses packages to be available to Fedora 8 users > even after its end of life ? No, once its end of life it is removed from the update system.

Leaving it in testing forever is a reasonable option, though my preference is to not update at all. Old Fedora releases should just get bug fixes and not major version updates - libvirt's almost OK because its ABI stable and has no UI, but we have caused regressions due to introducing new bugs. virt-manager has undergone major UI changes & redesign, and its really not the kind of thing that should be pushed into stable Fedora releases.
