hello is there any way that i can import an already existing kolla-ansible compute to my openstack ? migrating instances manually take a lot of time from me not really no
nova does not have a way to import exisitng comptue and more importantly the instances form a differnt deployment. we cant assume the flaovr for exampel would be the same so an import of a compute is a non trivial thing you would be be imporitng a comptue and all insntance on the compute which belong to multiple tenants consumeing resouce form a differnt glnace/neturon/cinder ectra then the new cloud. so there is no simple way to import the compute but you coudl perhaps look at os-migrate to "import" or migrate the instnaces. os-migrate is intended to automate moving instnace between clouds but its not an entirly lossless process as ips will change in the process. https://github.com/os-migrate/os-migrate
