Perhaps a virt issue related to libvirt XML?

> Perhaps a virt issue related to libvirt XML?

Seems so.
We indeed don't send anything besides the 'xml' attribute now, and in particular we don't send the 'memSize' attribute, but it seems that the 'xml' attribute is not persisted into the metadata volume and so VDSM invokes the legacy validation that is not supposed to pass anymore when it restores the data from the metadata volume.

That's weird, should have been fixed by 66971d3a8

Ah, I see. The "if" added in 66971d3a8 looks for the "xml" key - we should extend this check to work also with "_srcDomXML" key. We should move all the checks in a function, something like

  def has_xml_configuration(params):
    return "xml" in params or "_srcDomXML" in params

  and then in API.py:

  if not has_xml_configuration(vmParams):
    self._validate_vm_params(vmParams)
    self._fix_vm_params(vmParams)

we should not import vm.py in API.py, so, lacking a better place, we could put the new function in lib/vdsm/virt/utils.py

IIUC the _srcDomXML is there also for snapshots taken before 4.2, that's the libvirt xml without the metadata that vdsm relies on, and in that case this function should return a negative value, right?

True. In that case we need to do one additional check to see if the metadata is present or not.

patch merged, to appear in Vdsm 4.20.9 -> MODIFIED

user should never see this, thus doesn't deserve a doc_text.

Moving back to MODIFIED as we don't have 4.20.9 yet and our tests failed

Passed automation run over rhvm-4.2.0-0.6.el7

Verified

Failed in different execution.
