Description Daniel Berrangé 2016-12-21 14:09:21 UTC

Description of problem:
The current LUKS encryption support can only be used in combination with local files or block devices. This needs to be extended to cover usage with the QEMU native RBD, Gluster, iSCSI, NFS backends which don't expose any file in the host. It should already be possible to enable this at the QEMU level, so it should be a matter of just wiring up libvirt command line generator.

Version-Release number of selected component (if applicable):
libvirt-2.0.0-10.el7

Block devices as well? I could not make it working and libvirt docs shows only volume as file example http://libvirt.org/formatstorageencryption.html

So is luks block device supported by libvirt?

I meants using a logical storage pool in libvirt.
