Binary package “libnss-libvirt” in ubuntu eoan

nss plugins providing IP address resolution for virtual machines

 Libvirt is a C toolkit to interact with the virtualization capabilities
 of recent versions of Linux (and other OSes). The library aims at providing
 a long term stable C API for different virtualization mechanisms. It currently
 supports QEMU, KVM, XEN, OpenVZ, LXC, and VirtualBox.
 .
 This package contains two nss plugins for IP address resolution of libvirt
 managed virtual machines: the 'libvirt_guest' plugin uses libvirt's domain
 names while the 'libvirt' plugin looks at the guest's hostname.
