The libgovirt packages contain a library that allows applications to use the oVirt Representational State Transfer API to list virtual machines managed by an oVirt instance. The library is also used to get the connection parameters needed to establish a connection to the VMs using Simple Protocol For Independent Computing Environments or Virtual Network Computing . The spice-vdagent packages provide a SPICE agent for Linux guests. The virt-viewer packages provide Virtual Machine Viewer, which is a lightweight interface for interacting with the graphical display of a virtualized guest.
