is it possible to manual decide the host when instance is being created instead of automatic assign host [closed]
Openstack engine will automatic(certain algorithm) settle the instance to back-end host if the openstack have several nova-compute node in order to balance workload for host.
In the some situation, Can I assign the nova-compute node by manual? decide by person?
I observed the below parameters to describe host and hypervisor_hostname in openstack API guide document. OS-EXT-SRV-ATTR:host OS-EXT-SRV-ATTR:hypervisor_hostname
Can i use them to decide nova-compute node where i want to create instance?
I will test it and feedback
