Public bug reported:
Description
===========
Cold migration fails with shared storage, tested with NFS backend.
Server having flavor without swap set gets migrated without any issue.
Steps to reproduce
==================
Create flavor with swap - FLAVOR_SWAP
Create instance using the "FLAVOR_SWAP" flavor
Perform cold migration
Expected result
===============
VM should be migrated to new HOST
Actual result
=============
migration fails with error:
`reateWithFlags raise libvirtError('virDomainCreateWithFlags() failed')
libvirt.libvirtError: Cannot access storage file
'/var/lib/nova/instances/4f428161-6244-4de2-821f-019d4c087264/disk.swap' (as
uid:107, gid:107): No such file or directory`
