Gosuke Miyashita

The document discusses libvirt, a library that provides a virtualization API for managing virtual machines. It describes how libvirt interacts with virtualization systems like Xen and allows operations like listing domains, getting domain info, and performing actions like create, shutdown, and reboot. Code examples are provided in Perl and Python to connect to remote libvirt servers and get domain state information using libvirt and Avahi multicast DNS discovery.
