Openstack. "No valid host was found" for any image other than cirrOS

Question

I'm getting the following error on my Openstack (DevStack) every time I try to launch an image other than cirrOS. Walking through internet leads me to:

1. Openstack cannot allocate RAM, CPU resources. It's not true because I have a lot of RAM, disk space and CPU available.
2. set in nova.conf -> scheduler_default_filters=AllHostsFilter Tried without success.

This hapends to any image in any format that is other than cirrOS.

Update: Now it is clear that there is no direct answer to this question. Lets hope Openstack guys will provide more specific information in this error message

Answer 1

确保您选择的口味大小是“小”或更大，cirros 默认使用tiny，如果不更改，其他口味也是如此
