libvirt

README

coredns-libvirt

This plugin allows CoreDNS to resolve names matching libvirt domains. It is similar to the nss plugin libvirt_guest.

Usage

Currently this plugin can only be used in the guest mode.

Guest name

The functionality of libvirt guest is analogous to the libvirt_guest nss plugin, where we look for a match on the name of the libvirt domain, not necessarily a hostname.

Zones

If your zone isn't root ., you'll likely want to include the trim_suffix directive so you search for the correct name in your guests.

Filtering by network

If only some of the IPs assigned to the guests are reachable, you can filter them with the keep directive.

Example

vm:1053 {
  libvirt guest {
    trim_suffix vm
    keep 10.101.0.0/24
  }
}
