RE: [Xen-users] Xen with newer-than-126.96.36.199
I'm having problems with my dom0 linux kernel, which I beleive could be
fixed by going to a newer linux kernel. (The problems are not
related to XEN, and have to do with device driver support for ATAPI support
under SATA). I've tried updating to 2.6.17 _non-xen_ and my device
driver problems are solved. Now, if only I can update to 2.6.17 _with_
So I'd like to be able to run XEN with a 2.6.17 or later dom0
kernel. It's not clear to me how to do this or even if it's
possible. I'm running Gentoo. The latest xen-sources they
currently have available for emerge is 188.8.131.52
A few possible approaches
which I've considered:
- Convert a redhat fedora kernel-sources
package from RPM to tgz using rpm2targz, and try that. They seem to have
xen dom0 compatible release up to one of the 2.6.18 release candidates.
particular reason you can't juse use these packages directly? It seems like the
easiest way... Or is the problem that Gentoo doesn't have a RPM-capable
- Start with a
vanilla gentoo kernel-sources emerge, and apply whatever patches are necessary
to make them xen-dom0 compatible. I have absolutely no idea how to find
these patches, or how realistic a goal this is.
- Start with
the xen-sources 184.108.40.206
emerge, and apply
incrimental patches from kernel.org
to get it
up to 2.6.17 or later.
Any folks with wisdom to share on which of the
above approaches is best? Or any others I haven't thought of? And
any hints or tips that will help me along the way.
this was me, I would take the current Xen-Unstable (which uses 220.127.116.11), and
apply ONLY the patch that fixes the particular problem you're having (ATAPI +
SATA). There should be a patch available on the Linux Kernel Mailing List (I
presume) for this particular problem. If this patch doesn't apply cleanly, then
you may want to look at adding other patches prior to this patch, based on
what's needed. This will work best if there are relatively few changes to the
SATA/ATAPI components in between 18.104.22.168 and the 2.6.17 kernel that you need.
Which there is some chance that you'll get away with only one single patch. I
had a quick google for a suitable patch, but I couldn't find one - but if you
know what the exact problem description is, I think you may be able to find
it... I did find this tho': http://linux-ata.org/software-status.html#atapi which
states that ATAPI is fixed from 2.6.15, which means that the stock kernel that
comes with Xen should work. Presumably you're having some further problems to
that - I can't say because I don't quite know the ins/outs of SATA + ATAPI.
