The installation of KVM on a Linux host turns the host into a hypervisor. Virtual machines can be run on the hypervisor. KVM is one of a few full virtualization technologies under GNU General Public License and running on Linux.

'Common errors' means that the problems were not related to hardware properties, the network layout or other special implementation properties. Instead, the problems can occur in any KVM installation. That's why they are described here together with possible solutions and error causes if known.
