The ansible-vm part

1. create ubuntu 22.04 vm with 8 GB of disk (ansible-vm)
2. enter into it
3. run:

su # to become root
cd ~ # to go to root's home dir (important!)
apt update
apt -y install git
git clone https://github.com/dmitru4ok/virtualization-project.git
cd virtualization-project/telecomms/shell
chmod +x Main.sh
./Main.sh

4. The script will ask you for your vm password (we agreed on it earlier) and 3 pairs of OpenNebula credentials.
5. then ansible-vm long updating will start
6. after that, it will create webserver-vm, client-vm, and db-vm and populate hosts file with VM private ips.

8. ssh-keys will be added to the machines
