# Can Libvirt Networking be Disabled?

## Problem

A hypervisor, without a DHCP role assigned, has a running ***dnsmasq*** process. Can it be disabled? Is it needed?

{% tabs %}
{% tab title="None" %}

```none
libvirt+  1547    1  0 XXXYY ?     00:00:00 /usr/sbin/dnsmasq --conf-file=/var/lib/libvirt/dnsmasq/default.conf --leasefile-ro --dhcp-script=/usr/lib/libvirt/libvirt_leaseshelper
```

{% endtab %}
{% endtabs %}

## Environment

* Platform9 Managed OpenStack - All Versions

## Answer

Yes, Libvirt networking, which spawns a ***dnsmasq*** process on the hypervisors, may be disabled and is not needed by OpenStack. Refer to the [OpenStack documentation](https://docs.openstack.org/neutron/pike/admin/misc-libvirt.html#how-to-disable-libvirt-networks) for steps to disable it.
