Hello, there：
I wish to get some help from you. And here is my problem:
When I tried to boot a instance on OpenStack Kilo,
=======================================================================================================================nova
boot --flavor m1.tiny --image cirros-0.3.4-x86_64 --nic
net-id=3be58b93-32ad-42bb-80c7-7979554d6bc4 --security-group default --key-name
demo-key demo-instance7
=======================================================================================================================
the instance didn't boot as I expected and the "nova-compute.log"
file contains some sentences like this:
===================================nova-compute.log==============================================2015-08-25
09:42:53.009 6440 WARNING nova.virt.disk.api
