Hi,

I am running kvm-66 on top of a debian sid host with 2.6.24 (intel 32bit host).

Got the following in my logs today :

as I got no reply, I guess it is a bad setup on my part. If that might
help, this happenned while I was doing a "make -j" on webkit svn tree
(ie. heavy c++ compilation workload) .

No this is not bad setup.  No amount of bad setup should give this warning.

You didn't get a reply because no one knows what to make of it, and 
because it's much more fun to debate endianess or contemplete guests 
with eighty thousand disks than to fix those impossible bugs.  If you 
can give clear instructions on how to reproduce this, we will try it 
out.  Please be sure to state OS name and versions for the guest as well 
as the host.

Any sufficiently difficult bug is indistinguishable from a feature.

It is valid to have more than PAGES_PER_HPAGE in the largepage's
shadowed count. If the gpte read races with a pte-update-from-guest (and
the pte update results in a different sp->role), it might account twice
for a single gfn.

Such "zombie" shadow pages should eventually be removed through
recycling, allowing for instantiation of a large page, unless references
can be leaked. Can't spot such leakage problem though.

Thoughts?

That strikes me as unlikely (though a valid scenario).

An alternative explanation is that we're seeing a nonpae guest, so each 
page can be shadowed in two different roles (two quadrants for a pte 
page) or even four (for a pgd page).

Thomas, are you running a 32-bit nonpae guest?

Do not meddle in the internals of kernels, for they are subtle and quick to panic.

Yes it was 32bit nonpae guest on 32bit nonpae host.

Severals things :
 - I never reproduiced the problem
 - The problem happened under heavy load, and I was experiencing
slowdown on this laptop after a few hours of work. For example my
system was reporting 4500fps on glxgears after fresh boot, and 500fps
after a day of work. After some investigations, I found on the dell
website that my laptop had fans activation problems with my bios
version. After bios upgrade, my system does slows after heavy load. So
as my system was heating to much because of this bios problem, I think
you can forget my report.

kvm is version 66.

The offending guest was a 32bit winXp (don't know if this uses pae or
not) with 384mo of ram. we use tap networking and vnc access. The vms
on this server are qcow2 files stored lvm (this might be relevant as
lots of vfs calls are in the traces) :
/dev/mapper/volGroupe-VMs on /mnt/machines_virtuelles type ext3 (rw)
/dev/mapper/volGroupe-VMs_snapshots on /mnt/VMs_snapshots type ext3 (rw)

The command line used to start the vms looks like this :
/usr/bin/kvm -m 256 -hda /home/tom/kvm/root/root_vm.qcow2 -no-acpi
-net nic,model=e1000,macaddr=52:54:10:00:00:02 -net
tap,script=/etc/qemu-kvm.ifup,downscript=/etc/qemu-kvm.ifdown
-daemonize -monitor telnet:localhost:9002,server,nowait -vnc :2 -k fr

I attached our dmesg output with all the warnings we grabbed.
