This suggests that the xen_exchange_memory hypercall has failed for some
reason.

-12 is -ENOMEM but size is only 64M and this is start of day so I can't
think why this would be the case (or at least why it wouldn't always be
the case if it was happening at all).

Might be worth trying the dom0_mem hypervisor parameter to limit the
initial size of dom0, perhaps to 32G.

Following Ians suggestion I will summarize again, what I've written in
the bug report.

Passing dom0_mem=max:4GB to the hypervisor works around the issue. That
is, the dom0 with underlying hypervisor does boot. Please see
http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1698#c4 for a
full dmesg/xm info output.

The relevant part is:

node_to_cpu            : node0:0,2,4,6,8,10,12,14
                         node1:1,3,5,7,9,11,13,15
node_to_memory         : node0:21765
                         node1:24425
node_to_dma32_mem      : node0:0
                         node1:1969



Moreover my company is willing to pay anyone who fixes this bug a
symbolic fee of 1000 EUR as thank-you for letting us making use of Xen;
either personally to the contributor or to a (non-profit) organization
of the contributor's choice.

His 'node_to_dma32' ended being 0 and 62 respectivly. Not enough to allocate
the 64MB SWIOTLB buffer. Isn't there some logic in the Xen hypervisor to 
leave some swath of memory for DMA32?

Hmm.. iirc there was some discussions (and patches maybe?) related to Xen dma32
reservations some time ago..

I was speaking earlier today to Pasi about this bug again by accident.
There he asked whether I did try to boot the xen-4.0-testing tree. Now I
did, as I built the most recent -testing snapshot and I have some more
to add:

Booting the Xen hypervisor in version 4.0.2-rc1-pre built by myself on
the affected system resulted in no failure for Debian's stock
2.6.32-5-xen-amd64 kernel. Jeremy's xen tree at
git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git (resulting
in 2.6.32.27) failed to boot, but that is my fault as I was too lazy to
build an appropriate .config. So this is NOT related to the bug.

So the question is now, whether there was a bug in 4.0.1 that has been
fixed in -testing which fixes this one as well (or if it is a duplicate
perhaps?), or if Debian introduced that bug. Would someone mind finding
this out together with me?

Serial output is now:

As far as I can tell Debian does not patch the hypervisor at all, it is
just stock 4.0.1.

That makes it seem likely that the issue is fixed in xen-4.0-testing.hg
and will be in the 4.0.2 release.

If you wanted to figure out which changeset then you could bisect the
hypervisor changes between the RELEASE-4.0.1 tag in xen-4.0-testing.hg
and the version you tested which was ok.

Ian.

There was some fix for the VT-d allocation that ended up crashing Dom0
(b/c of an memory accounting issue).

It could have been that was what you hit. I don't remember the changeset
number, but you could try booting your old hypervisor without the Vt-D
and see if that was it (iommu=off) ?

Chances are, as I already mentioned the machine boots fine if I disable
VMX in bios. Booting with "iommu=off" has the same effect.

I skipped through the changelogs recently and found, one (or more) of
the following changesets _should_ fix the issue. I'm lacking any
knowledge about the hypervisor's internal subsystems and code paths
though. So my seeked fix might or might not be within that subset at all.

As said, I look for the exact fix, to get Debian people a hint about
what to backport for their 4.0.1 soon-to-be-stable package.

Hmm, let me ping Andrew, he might know. Andrew, do you remember what fix
you needed to get Dom0 to boot when you had more than 64GB of memory
with the VT-d enabled?

 From the xen-4.0-testing.hg repo:

changeset:   21403:e7d9d8d46730
user:        Keir Fraser <keir@xen.org>
date:        Wed Dec 15 10:31:59 2010 +0000
files:       xen/arch/x86/domain_build.c
description:
x86/iommu: account for necessary allocations when calculating Dom0's
initial allocation size

As of c/s 21812:e382656e4dcc, IOMMU related allocations for Dom0
happen only after it got all of its memory allocated, and hence the
reserve (mainly for setting up its swiotlb) may get exhausted without
accounting for the necessary allocations up front.

Thank you very much, Thomas. I will forward this to Debian people, so
they hopefully will backport that fix.

I have verified this now and can confirm this commit fixes the problem.
Thank you very much.

This closes bug #1698 as well.
