[Bug 1567807] Re: nova delete doesn't work with EFI booted VMs

[Michael Still]

Your fix looks reasonable to me, but we'd need a test as well I think.
I've tagged this as being of possible backport interest to mitaka as
well.

Title:
  nova delete doesn't work with EFI booted VMs

Status in OpenStack Compute (nova):
  Triaged
Status in nova package in Ubuntu:
  Confirmed

Bug description:
  I've been setting up a Mitaka Openstack using the cloud archive
  running on Trusty, and am having problems working with EFI enabled
  instances on ARM64.

  I've done some work with wgrant and gotten things to a stage where I
  can boot instances, using the aavmf images.

  However, when I tried to delete a VM booted like this, I get an error:

    libvirtError: Requested operation is not valid: cannot delete
  inactive domain with nvram

  I've included the full traceback at
  https://paste.ubuntu.com/15682718/.

  Thanks to a suggestion from wgrant again, I got it working by editing nova/virt/libvirt/guest.py in delete_configuration() and replacing  self._domain.undefineFlags(libvirt.VIR_DOMAIN_UNDEFINE_MANAGED_SAVE) with self._domain.undefineFlags(libvirt.VIR_DOMAIN_UNDEFINE_MANAGED_SAVE | libvirt.VIR_DOMAIN_UNDEFINE_NVRAM).
  I've attached a rough patch.

  Once that's applied and nova-compute restarted, I was able to delete
  the instance fine.

  Could someone please investigate this and see if its the correct fix,
  and look at getting it fixed in the archive?

  This was done on a updated trusty deployment using the cloud-archives
  for mitaka.

  $ dpkg-query -W python-nova
  python-nova     2:13.0.0~b2-0ubuntu1~cloud0

  Please let me know if you need any further information.
