Hey Sebastien,
I hadn't actually used vhd files so I can't comment on that.
There was bug that was found by Joe Jin
(http://lists.xensource.com/archives/html/xen-devel/2011-07/msg00275.html)
but that is when the disk is mounted - but you don't even get to that.
Is this _only_ happening with vhds? does it appear to exist
with phy's?

That is expected .. the upstream version of QEMU does not have all
the bells and whistles the older versions had.
