Ansible primarily runs in push mode using SSH, but you can also run Ansible using ansible-pull, where you can install Ansible on each agent, download the playbooks locally, and run them on individual machines.

Deployments are made over ssh, To speed up default SSH connections, you can always enable ControlPersist and the pipeline mode, which makes Ansible faster and secure.

On linux:

sudo apt install ansible 

Working with virutal machines, install:

$ sudo apt install virt-manager 
$ sudo apt install qemu-kvm libvirt-bin
