Having centos compute node
I am in a situation where controller runs fedora and compute nodes will be running centos. I am wondering if the centos has to be instlled with nova-compute or when adding the compute node to the controller config, it automatically installs it in the compute node. One more q I have is, if the centos based compute node has nova-compute installed in it, would the controlled reinstall it or just establishes connection with the existing agent?
