This is the final chapter; we looked at the potential sources of failures inside oVirt. At first glance, oVirt seems a complicated mechanism; so if a problem occurs, it is important to know in which direction to look for a solution. Here we have considered the main ways to find solutions that can solve most of the problems. However, to successfully address any problems that may arise, it is necessary to know what's inside oVirt and what components it consists of. In this case, finding a solution is fairly simple. Always try to look behind the screen. Good luck!
