I have added new compute hosts on my OpenStack (ROCKY) Cluster. while creating new VMs on newly added node, i am getting following error Error: Failed to perform requested operation on instance "7", the instance has an error status: Please try again later [Error: No valid host was found. There are not enough hosts available.].

Please help.

Thanks, Abhishek

What do the Nova logs say?

nova service-list
nova hypervisor-stats

Aha, it looks like there is a name conflict. The resolutions suggested in https://ask.openstack.org/en/question/119842/conflicting-resource-provider-name/ (this post) should help you delete the older entry, if you don't need the existing compute7.
