zun compute start error with keystone conflict

[BY]

After I completed the basic components of openstack and the basic components of zun, all the steps were OK, but the following error was displayed when zun compute started on the compute node. I can't understand where the problem occurred. I hope someone can help. In addition, I have also tried other versions of openstack and zun, but this problem always occurs in the end.

Hello, I encountered the same problem as you. I have solved it, the following operations can help you:

Edit the /etc/zun/zun.conf

in the [compute] section, configure the 'host_shared_with_nova':

[compute]
...
host_shared_with_nova = true

Then, restart zun-compute

systemctl restart zun-compute
