-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi Dmitry, I've been using Ubuntu 14.04LTS + Icehouse /w CEPH as a storage backend for glance, cinder and nova (kvm/libvirt). I *really* would love to see this patch cycle in Juno. It's been a real performance issue because of the unnecessary re-copy from-and-to CEPH when using the default "boot from image"-option. It seems that the your fix would be the solution to all. IMHO this is one of the most important features when using CEPH RBD as a backend for Openstack Nova. Can you point me in the right direction in how to apply this patch of yours on a default Ubuntu14.04LTS + Icehouse installation? I'm using the default ubuntu packages since Icehouse lives in core and I'm not sure how to apply the patch series. I would love to test and review it.
