Hi everyone, I need to port over an old RHEL3 box to a xen domU (just for a little while until I can transfer all of its services over to a new domain). I was hoping to get a domU supported kernel so I can run it as a PV guest and found this page: http://xen.org/download/dl_304guest_rhel3.html ...but the links to the actual kernels come up with 404 errors. Anyone know where I can get this kernel from? Thanks, Peter _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

You MIGHT be able to hack a 2.6 or 3.0 PV kernel to work with RHEL3, but it will be unsupported. Another alternative is to contact Redhat. IIRC the supported configuration is to use HVM (or KVM, if your host is RHEL6), but you might be able to get PV drivers. -- Fajar _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Thanks for your reply! Doing this, will just redirect the current content of "xm dmesg". I could have lost some value. I really want all "xm dmesg" ouput to be save in a file!

What I have actually ended up doing in the past is getting RHEL to work with a 2.6 kernel (albeit with a few bugs of its own that way). Would using the (buggy) 2.4 kernel be any worse than that?

People who only downloaded the binaries back then could always request the source by written notice, as required by GPL. .. that''s not very nice or practical though.

There is no such requirement that "source code has to remain available". There are some clauses which sound superficially like such a requirement but they are time limited and in any case do not apply in every case of distribution of a work since there are other alternatives allowed by the license.> No it''s not really a GPL violation. When the binary was still available, > also the sources were available.Correct. These binary RPMs were always accompanied by the corresponding source RPM and therefore clause 3(a) of the GPL is satisfied: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or,> People who only downloaded the binaries back then could always request > the source by written notice, as required by GPL.That is clause 3(b): b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, AFAIK there was no explicit written offer given with these kernels so strictly speaking this clause is not active. Note that the sub-clauses of section 3 are _alternatives_ which may be selected by the distributor and since option 3(a) is satisfied this is not a GPL violation.> .. that''s not very nice or practical though.Well, if clause 3(b) had been in effect it would have been their right though, regardless of the practicalities.> I think the reason why the rhel3 pv kernel downloads were removed > was because the kernel was so buggy and it''s better if noone uses them.Agreed. Given the presence of supported by Red Hat PV drivers for RHEL3 HVM guests I would strongly recommend using those and not the unsupported kernels that used to be on xenbits. If nothing else then the fact that they haven''t been updated for ~4 years (i.e. lack security updates over that period) should be enough to put most people off.

I stand corrected.>> I think the reason why the rhel3 pv kernel downloads were removed >> was because the kernel was so buggy and it''s better if noone uses them. > > Agreed.

Still, it would be nice to have the kernel above available for those who really need it, with the full understanding that it is no longer supported, of course, especially since some people don''t have the option to run HVM guests. As I said before I was able to get RHEL3 to run with a newer 2.6 kernel but some things were buggy (modprobe comes to mind, I had to put all the modules I needed in the initrd and force them to load at boot time). I was hoping for a better pv guest alternative to upgrading the kernel to 2.6. Also, when I port a RHEL3 box over to a VM it is almost always a temporary situation where the current need is just to get it off of existing hardware quickly and the future plan to migrate its functions to a more modern distro.

If you really feel you cannot use the supported stuff from Red Hat then some older XenServer versions also contained similar RPMs, which still appear to be available: http://updates.vmd.citrix.com/XenServer/5.5.0/rhel3x Obviously these are completely unsupported in this context, either by xen.org or the XenServer folks. These appear to have a few more fixes (over the same rhel3x baseline) than the ones previously on xen.org but I guess that is a good thing.

I will try to go the supported route, but it''s good to know that this option is there, and I think it''s a better one than trying to make a 2.6 kernel work.> Obviously these are completely unsupported in this context, either by > xen.org or the XenServer folks.

This looks like a good option if the HVM route won''t work, imo.
