Title:
  in pike release, UCA changed the nova code and break the old qemu
  binary

Status in Ubuntu Cloud Archive:
  Confirmed

Bug description:
  Kolla project is using UCA pike binary. But with some issue, we
  fallback to use qemu 2.5 + ceph Jewel by ping the package version.
  Then found this issue.

  After checked the nova/virt/images.py files before the one in UCA and
  nova upstream code. got following

  $ diff ~/openstack/nova/nova/virt/images.py images.py(from UAC)
  60c60,61
  <         cmd = ('env', 'LC_ALL=C', 'LANG=C', 'qemu-img', 'info', path)
  ---
  >         cmd = ('env', 'LC_ALL=C', 'LANG=C',
  >                'qemu-img', 'info', '--force-share', path)

  
  UCA add "--force-share" parameter roughly, which make nova can not work with old qemu-img binary.

  
  Since nova 16.0.2, this issue have be fixed by upstream[0]

  So you upgrade the nova code to the 16.0.2 at least? then nova package
  in ubuntu binary will support all qemu version.

  Thanks a lot.
