Description Fabian Deutsch 2015-10-21 15:51:56 EDT
Description of problem:
When using the appliance flow in HE setup, the extraction is taking a large portion of the setup time.

Version-Release number of selected component (if applicable):
3.6

How reproducible:
always

Steps to Reproduce:
1. Use appliance flow in
2.
3.

Actual results:
Extraction process takes long

Expected results:
Extraction process is quick

Raising the priority, because the flow could be nice, but is really slowed down due to this bug.

Ryan, could you quantify the slow down compared to the whole installation duration?

It's not really a bug, it's an RFE: it could be faster but it's working.
The issue is about python not efficiently handling sparse files so the real gain depends just from the image sparseness.
Comment 3 Fabian Deutsch 2015-10-22 07:47:25 EDT
Agreed, it's an RFE.
Comment 4 Yaniv Kaul 2015-10-22 15:10:01 EDT
Are we running virt-sparsify and virt-sysprep on the image before packing it?
Comment 5 Fabian Deutsch 2017-01-27 04:51:28 EST
Yes, IIRC.

The files should be sparse, but as Simone says: Python does not handle those efficiently when extracting tars.
