I have the same problem with a freshly created qcow2 image using the
qemu-img-xen tool.  The original qcow2 image works perfectly with
tap:qcow2, but attempting to use it as a base for a new image halts the
boot immediately.  The xend.log file don't show any errors, it only
points me to the VM-specific log, which just stops dead.

Perhaps this functionality isn't supported?
