We reproduiced this on a production machine, running with :

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.
