Description of problem:
Output allocation mode always is preallocated when using virt-v2v convert guest to openstack with setting disk type as raw

Steps to Reproduce:
Scenario1:
1.Prepare a guest, the disk type is "raw"

This is a bug in glance - it doesn't preserve sparseness.
You can try to use '-of qcow2'. Since qcow2 doesn't require
sparseness to be preserved, the resulting image in glance will
be smaller.
We document this problem in the manual already:
http://libguestfs.org/virt-v2v.1.html#glance-and-sparseness
so I don't think this is a bug in libguestfs. (It is certainly
a bug in glance however!)

Hi Richard,
Thanks for your reply, yes, it is the openstack bug rather than virt-v2v, could you provide bug ID about openstack doesn't preserve sparseness for us further tracking which I didn't find in bugzilla.

I think Richard means the bug you file is an openstack bug instead of virt-v2v.

The glance bug is this one:
https://bugs.launchpad.net/glance-store/+bug/810493
I'm closing the current bug as this is a known issue in
glance that can't be solved in virt-v2v, and in any case it
is already documented in the virt-v2v manual page.
