No, I exclusively use file-backed virtual disks for my domUs,
and never seen this kind of issue.

now I never used qemu-img-xen to create a disk image, but
dd if=/dev/zero.  Is qemu-img-xen creating a sparse file ? this may
be an issue.

I've not switched my production servers to netbsd-7 and xen 4.5 yet,
but my test machine is running it for some time, and create/destroy
several domUs every nights. I've not noticed problems.
