In particular, this line: https://github.com/openstack/nova/blob/stable/ocata/nova/virt/libvirt/driver.py#L1149 if os.path.exists(inst_base) and not root_disk.exists(): try: shutil.rmtree(inst_base) except OSError as e: if e.errno != errno.ENOENT: raise Causes the instance basedir which includes the instances libvirt.XML file to be deleted. The above needs to be changed to this in order to prevent BFV instances from being destroyed on resize... if os.path.exists(inst_base) and not root_disk.exists() and not compute_utils.is_volume_backed_instance(instance._context, instance): This bug was reported and the fix confirmed by Joris S'heeran To manage notifications about this bug go to: https://bugs.launchpad.net/nova/+bug/1728603/+subscriptions -- Mailing list: https://launchpad.net/~yahoo-eng-team Post to : yahoo-eng-team@lists.launchpad.net Unsubscribe : https://launchpad.net/~yahoo-eng-team More help : https://help.launchpad.net/ListHelp
