Hey everyone, I was hoping I could have some approval and feedback for both my blueprint and code submission to Openstack. I have code for setting compression level for XenAPI. This taps into the create_tarball hook and sets the GZIP environment variable as set by nova.conf on compute. I believe the code should work, but I'm struggling a bit with test cases. Appreciate any help or feedback you can give me. Blueprint: https://blueprints.launchpad.net/nova/+spec/image-compression-mode Code review: https://review.openstack.org/#/c/31898/ Thanks, Teran
