Want to see if I can get a couple old servers running under Xen. They both need custom kernels. One needs to run sco executables and need the abi patches. The other is for win4lin and needs win4lin patches. Where are the xen kernel patches? Are there patches for older kernels that work with the current xen? It''s improbably I will find abi or win4lin patches for a recent kernel. For win4lin see one for 2.6.14.3 for abi see mention of one for 2.6.16. I suppose HVM could be used, but do not have anything that supports it at the moment. If one did use HVM would one still have the disk and lan performance issues windows has?

You can generate your own patches with "make mkpatches" in the Xen tree. You''ll need to set the "LINUX_VER" to 2.6.14.3 in .../buildconfigs/mk.linux-2.6-xen And there''s absolutely no guarantee that your patches will apply to this kernel version, as it''s quite ancient... It may be a BETTER option to try to forward port the win4lin/sco abi changes to the current Xen kernel version - as the patches for the Linux kernel in my .../patches/linux-2.6.16.29/ is around 7500 lines of patches. I doubt the size of the sco/win4lin patches are that big (although I guess win4lin may be quite big), so it''s possibly easier to make those work on a later kernel version than taking Xen back several releases... -- Mats> > I suppose HVM could be used, but do not have anything that supports it > at the moment. > If one did use HVM would one still have the disk and lan performance > issues windows has? > > Thanks > > John > > -- > John McMonagle > IT Manager > Advocap Inc. > > > > _______________________________________________ > Xen-users mailing list > Xen-users@lists.xensource.com > http://lists.xensource.com/xen-users > > >_______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Will I need the source from here? http://xensource.com/download/dl_303tarballs.html Looks there are some current abi patches but not win4lin. Is there any commitment to maintain kernel compatibility at least over a major version? New version of xen have been coming out pretty often and it could get challenging if I have custom kernels. This brings me back to HVM. Does linux have good disk and network performance using HVM?

Every new release of Xen can realisticly be expected to upgrade to one of the newer kernel releases - it may not be THE LATEST, but something near the latest that is stable will be the new kernel after a release - then that kernel is usually kept stable within that "unstable" time between (say) 3.0.4 and 3.0.5.> New version of xen have been coming out pretty often and it could get > challenging if I have custom kernels.Yes, unfortunately, I don''t think you will win against Novell, RedHat & Co... :-(> > This brings me back to HVM. Does linux have good disk and network > performance using HVM?Define "good" ... ;-) For Linux, there''s para-virtual drivers, so you should get similar performance to a para-virtual kernel build. For Windows, you''ll have to pay to get a commercial version of Xen with Windows PV drivers, as no one has yet published any "free" version of para-vritual drivers for Windows. -- Mats> > Thanks > > John > > >>I suppose HVM could be used, but do not have anything that > supports it > >>at the moment. > >>If one did use HVM would one still have the disk and lan performance > >>issues windows has? > >> > >>Thanks > >> > >>John > >> > >> > >> > > > -- > John McMonagle > IT Manager > Advocap Inc. > > > > _______________________________________________ > Xen-users mailing list > Xen-users@lists.xensource.com > http://lists.xensource.com/xen-users > > >_______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
