Sinseramente no recuerdo de donde lo saqué, le hice un par de modificaciones.

También hay que agregar a la configuración de sudo lo siguiente al final del archivo en el KVM Host:

nagios ALL=(root) NOPASSWD:/usr/bin/virsh

Luego agregar a su nrpe.cfg, por ejemplo:

command[check_vm01]=/ruta/hacia/check_virt vm01

Y ya lo pueden probar desde su servidor nagios:

nagios-server$ /usr/lib/nagios/plugins/check_nrpe -H 99.99.99.99 -c check_vm01 cge-almacen1 Running - status 0
