The third is nova reschedule the instance infinitely


For the first error, the nova api check the image size with flavor size, but the image size is actually size that different with virtual size. In libvirt driver check the virtual size.

the image properties as blow:

In nova api, it will check the 'Minimum Disk Required'. User should
specific the 'Minimum Disk Required' for image. So I think this isn't a
bug for nova

For second error, that is wrong way to use network_info object, this
should be fixed.

For third error, after change conductor to build new instance, the retry
info is missing. we should fix is also.

  The third is nova reschedule the instance infinitely

  
  For the first error, the nova api check the image size with flavor size, but the image size is actually size that different with virtual size. In libvirt driver check the virtual size.

  the image properties as blow:

  In nova api, it will check the 'Minimum Disk Required'. User should
  specific the 'Minimum Disk Required' for image. So I think this isn't
  a bug for nova

  For second error, that is wrong way to use network_info object, this
  should be fixed.

  For third error, after change conductor to build new instance, the
  retry info is missing. we should fix is also.
