[Bug 1562266] Re: VMware: resize instance change instance's hypervisor_hostname

 

Well, the resize operation implies to reschedule the instance to a new
host (given the flavor is different) than can possibly be the same host
if the config option allow_resize_to_same_host is set to True (defaulted
to False).

So, it's perfectly normal to have the hypervisor_hostname changed if you
resize an instance.

Title:
  VMware: resize instance change instance's  hypervisor_hostname

Status in OpenStack Compute (nova):
  Invalid

Bug description:
  Nova version: master
  Virt driver: VCDriver

  Nova compute1   <-->   VMware cluster1
  Nova compute2   <-->   VMware cluster2

  Resize an instance(original hypervisor_hostname is
  domain-c9(cluster2)) in VMware, makes instance's hostname
  changed(Before we verify,  hypervisor_hostname had changed to
  domain-c7(cluster1)).

  Then we checked in vCenter, the instance still located in cluster2.
