Large number of VMs (~1000) and libvirt exception
Hi,
I have a problem with uncaught exception in nova. I was not able to schedule one thousand of VMs, because the closer I was to schedule all needed VMs, the more VMs were throwing exceptions. This is what 'nova show' shows:
{u'message': u'AttributeError', u'code': 500, u'details': u'\'NoneType\' object has no attribute \'lookupByName\'

', u'created': u'2013-09-03T11:57:38Z'}
Any suggestions on that?
