esubramanian e51555b3f0 Removes the delta file once image is extracted 
When creating a live snapshot of an instance, nova creates a
copy of the instance disk using a QEMU shallow rebase. This
copy - the delta file - is then extracted and uploaded. The
delta file will eventually be deleted, when the temporary
working directory nova is using for the live snapshot is
discarded, however, until this happens, we will use 3x the
size of the image of host disk space: the original disk,
the delta file, and the extracted file. This can be problematic
when concurrent snapshots of multiple instances are requested
at once.

The solution is simple: delete the delta file after it has
been extracted and is no longer necessary.

OpenStack Nova

image

OpenStack Nova provides a cloud computing fabric controller, supporting a wide variety of compute technologies, including: libvirt (KVM, Xen, LXC and more), Hyper-V, VMware, XenServer, OpenStack Ironic and PowerVM.

Use the following resources to learn more.

API

To learn how to use Nova's API, consult the documentation available online at:

Operators

To learn how to deploy and configure OpenStack Nova, consult the documentation available online at:

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:

Developers

For information on how to contribute to Nova, please see the contents of the CONTRIBUTING.rst.

Any new code must follow the development guidelines detailed in the HACKING.rst file, and pass all unit tests.
