Hi, Guys
I am studying ovirt, and now I am checking how vdsm manage VM.
But now I have a trouble about the process "shutdown VM".
I know that when start up a VM, a vm object will be added to the
vmContainer.
And I think the vm object will be deleted from vmContainer when
shutdown/poweroff since
the code will check whether the vm object exist in vmContainer when
start up VM.
---------------------------------
# cat vdsm/API.py
def create(self, vmParams):
"""
Start up a virtual machine.
:param vmParams: required and optional VM parameters.
:type vmParams: dict
"""
vmParams['vmId'] = self._UUID
try:
if vmParams.get('vmId') in self._cif.vmContainer:
self.log.warning('vm %s already exists' % vmParams['vmId'])
return errCode['exist']
... snip ...
---------------------------------
I found the vm object will be deleted from vmContainer when poweroff.
but I did not find where vm obeject be deleted from vmContainer when
shutdown.
Does someone can help me?
---------------------------------
# cat vdsm/virt/vm.py
def destroy(self):
self.log.debug('destroy Called')
response = self.doDestroy()
if response['status']['code']:
return response
# Clean VM from the system
self.deleteVm()
... snip ...
def deleteVm(self):
"""
Clean VM from the system
"""
try:
del self.cif.vmContainer[self.conf['vmId']]
self.log.debug("Total desktops after destroy of %s is %d",
self.conf['vmId'], len(self.cif.vmContainer))
except Exception:
self.log.error("Failed to delete VM %s", self.conf['vmId'],
exc_info=True)
... snip ...
