[Bug 1376615] Re: Libvirt volumes are copied in case of block live migration
Based on the comments in the proposed patch:
https://review.openstack.org/125616
the root cause of this issue requires enhancement in libvirt before
anything can be done about it in nova. So, marking this as
Opinion/Wishlist as an enhancement that can be addressed if libvirt is
first enhanced.

Title:
Libvirt volumes are copied in case of block live migration
Status in OpenStack Compute (Nova):
Opinion
Bug description:
When doing a block live migration with volumes attached, the libvirt
drive-mirror operation tries to sync all the disks attached to the
domain, even if they are external volumes. It should only do so for
the ephemeral storage, so we need to be able to pass that information.
