Install Ravada on Fedora
Ravada works in any Linux distribution.
RPM packages are kindly built by a third party. Please check the release available. If you want the latest verstion it is adviced to install it on top of Ubuntu or Debian.
It depends on the number and type of virtual machines. For common scenarios are server memory, storage and network bandwidth the most critical requirements.
RAM is the main issue. Multiply the number of concurrent workstations by the amount of memory each one requires and that is the total RAM the server must have.
The faster the disks, the better. Ravada uses incremental files for the disks images, so clones won’t require many space.
Follow this guide if you are only upgrading Ravada from a previous version already installed.
Fedora and EPEL7
You can install ravada using the ‘dnf’ package manager.
sudo dnf install ravada
It is required a MySQL server, in Fedora we use MariaDB server. It can be installed in another host or in the same as the ravada package.
sudo dnf install mariadb mariadb-server
And don’t forget to enable and start the server process:
sudo systemctl enable --now mariadb.service
sudo systemctl start mariadb.service
MySQL database and user
It is required a database for internal use. In this examples we call it ravada. We also need an user and a password to connect to the database. It is customary to call it rvd_user. In this stage the system wants you to set a password for the sql connection.
If installing ravada on Ubuntu 18 or newer you should enter your user’s password instead of mysql’s root password.
Create the database:
sudo mysqladmin -u root -p create ravada
Grant all permissions on this database to the rvd_user:
sudo mysql -u root -p ravada -e "grant all on ravada.* to rvd_user@'localhost' identified by 'Pword12345*'"
The password chosen must fulfill the following characteristics:
At least 8 characters.
At least 1 number.
At least 1 special character.
Create a config file at /etc/ravada.conf with the username and password you just declared at the previous step. Please note that you need to edit the user and password via an editor. Here, we present Vi as an example.
sudo vi /etc/ravada.conf
Ravada web user
Add a new user for the ravada web. Use rvd_back to create it. It will perform some initialization duties in the database the very first time this script is executed.
When asked if this user is admin answer yes.
sudo /usr/sbin/rvd_back --add-user admin
The server must be able to send DHCP packets to its own virtual interface.
KVM should be using a virtual interface for the NAT domnains. Look what is the address range and add it to your iptables configuration.
First we try to find out what is the new internal network:
sudo route -n
192.168.122.0 0.0.0.0 255.255.255.0 U 0 0 0 virbr0
So it is 192.168.122.0 , netmask 24. Add it to your iptables configuration:
sudo iptables -A INPUT -s 192.168.122.0/24 -p udp --dport 67:68 --sport 67:68 -j ACCEPT
To confirm that the configuration was updated, check it with:
sudo iptables -S
The client must have a spice viewer such as virt-viewer. There is a package for linux and it can also be downloaded for windows.
The Ravada server is now installed, learn how to run and use it.
Struggling with the installation procedure ? We tried to make it easy but let us know if you need assistance.
