At the moment the API for get_vnc_console is:
def get_vnc_console(self, req, id, body):
"""Get text console output."""
context = req.environ['nova.context']
context.can(rc_policies.BASE_POLICY_NAME)
# If type is not supplied or unknown, get_vnc_console below will cope
console_type = body['os-getVNCConsole'].get('type')
instance = common.get_instance(self.compute_api, context, id)

output = self.compute_api.get_vnc_console(context,
instance,
console_type)

InternalError isn't handled by the API, so you get "Unexpected API Error. Please report this at http://bugs.launchpad.net/nova/ and attach the Nova API log if possible. <class 'InternalError_Remote'>" |
