[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.

** Changed in: nova

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.
