Title:
vm would be stuck in unshelving when unshelve fails
Status in OpenStack Compute (Nova):
Fix Released
Bug description:
when unshelve a vm, if this vm has been offloaded, the process would involve
re-scheduling.
in nova/conductor/manager.py def unshelve_instance(self, context, instance):
elif instance.vm_state == vm_states.SHELVED_OFFLOADED:
try:
with compute_utils.EventReporter(context, self.db,
'get_image_info', instance.uuid):
image = self._get_image(context,
sys_meta['shelved_image_id'])
except exception.ImageNotFound:
with excutils.save_and_reraise_exception():
LOG.error(_('Unshelve attempted but vm_state not SHELVED '
'or SHELVED_OFFLOADED'), instance=instance)
instance.vm_state = vm_states.ERROR
instance.save()
filter_properties = {}
hosts = self._schedule_instances(context, image,
filter_properties,instance)
<<<<<this re-scheduling would cause exception,when it occurs,the
<<<<<<instance will be stuck in task_state: unshelving forever
host = hosts.pop(0)['host']
