The <code class="language-plaintext highlighter-rouge">default_prefix</code> options allow you to set the guest name prefix.</li> <li><code class="language-plaintext highlighter-rouge">disk_bus</code> - The type of disk device to emulate. Defaults to virtio if not set. Possible values are documented in Libvirt’s <a href="http://libvirt.org/formatdomain.html#elementsDisks">description for <em>target</em></a>.

NOTE: this option applies only to the disks associated with a box image.</li> <li><code class="language-plaintext highlighter-rouge">disk_device</code> - The disk device to emulate. Defaults to vda if not set, which should be fine for paravirtualized guests, but some fully virtualized guests may require hda. NOTE: this option also applies only to disks associated with a box image.</li> <li><code class="language-plaintext highlighter-rouge">disk_driver</code> - Extra options for the main disk driver (<a href="http://libvirt.org/formatdomain.html#elementsDisks">see Libvirt documentation</a>). NOTE: this option also applies only to disks associated with a box image. In all cases, the value <code class="language-plaintext highlighter-rouge">nil</code> can be used to force the hypervisor default behaviour (e.g. to override settings defined in top-level Vagrantfiles). Supported options include: <ul> <li><code class="language-plaintext highlighter-rouge">:cache</code> - Controls the cache mechanism. Possible values are “default”, “none”, “writethrough”, “writeback”, “directsync” and “unsafe”.</li> <li><code class="language-plaintext highlighter-rouge">:io</code> - Controls specific policies on I/O. Possible values are “threads” and “native”.</li> <li><code class="language-plaintext highlighter-rouge">:copy_on_read</code> - Controls whether to copy read backing file into the image file. The value can be either “on” or “off”.</li> <li><code class="language-plaintext highlighter-rouge">:discard</code> - Controls whether discard requests (also known as “trim” or “unmap”)

</code></pre></div></div> <p>In example below, one network interface is configured for VM <code class="language-plaintext highlighter-rouge">test_vm1</code>. After you run <code class="language-plaintext highlighter-rouge">vagrant up</code>, VM will be accessible on IP address <code class="language-plaintext highlighter-rouge">10.20.30.40</code>. So if you install a web server via provisioner, you will be able to access your testing server on <code class="language-plaintext highlighter-rouge">http://10.20.30.40</code> URL. But beware that this address is private to Libvirt host only. It’s not visible outside of the hypervisor box.</p> <p>If network <code class="language-plaintext highlighter-rouge">10.20.30.0/24</code> doesn’t exist, provider will create it. By default created networks are NATed to outside world, so your VM will be able to connect to the internet (if hypervisor can). And by default, DHCP is offering addresses on newly created networks.</p> <p>The second interface is created and bridged into the physical device <code class="language-plaintext highlighter-rouge">eth0</code>. This mechanism uses the macvtap Kernel driver and therefore does not require an existing bridge device. This configuration assumes that DHCP and DNS services are being provided by the public network. This public interface should be reachable by anyone with access to the public network.</p> <h3 id="private-network-options"> <a href="#private-network-options" class="anchor-heading" aria-labelledby="private-network-options"><svg viewBox="0 0 16 16" aria-hidden="true"><use xlink:href="#svg-link"></use></svg></a> Private Network Options </h3> <p><em>Note: These options are not applicable to public network interfaces.</em></p> <p>There is a way to pass specific options for Libvirt provider when using <code class="language-plaintext highlighter-rouge">config.vm.network</code> to configure new network interface. Each parameter name starts with <code class="language-plaintext highlighter-rouge">libvirt__</code> string. Here is a list of those options:</p> <ul> <li><code class="language-plaintext highlighter-rouge">:libvirt__network_name</code> - Name of Libvirt network to connect to. By default, network ‘default’ is used.</li> <li><code class="language-plaintext highlighter-rouge">:libvirt__netmask</code> - Used only together with <code class="language-plaintext highlighter-rouge">:ip</code> option. Default is ‘255.255.255.0’.</li> <li><code class="language-plaintext highlighter-rouge">:libvirt__network_address</code> - Used only when <code class="language-plaintext highlighter-rouge">:type</code> is set to <code class="language-plaintext highlighter-rouge">dhcp</code>. Only <code class="language-plaintext highlighter-rouge">/24</code> subnet is supported. Default is <code class="language-plaintext highlighter-rouge">172.28.128.0</code>.</li> <li><code class="language-plaintext highlighter-rouge">:libvirt__host_ip</code> - Address to use for the host (not guest). Default is first possible address (after network address).</li> <li><code class="language-plaintext highlighter-rouge">:libvirt__domain_name</code> - DNS domain of the DHCP server. Used only when creating new network.</li> <li><code class="language-plaintext highlighter-rouge">:libvirt__dhcp_enabled</code> - If DHCP will offer addresses, or not. Used only when creating new network. Default is true.</li> <li><code class="language-plaintext highlighter-rouge">:libvirt__dhcp_start</code> - First address given out via DHCP. Default is third address in range (after network name and gateway).</li> <li><code class="language-plaintext highlighter-rouge">:libvirt__dhcp_stop</code> - Last address given out via DHCP. Default is last possible address in range (before broadcast address).</li> <li><code class="language-plaintext highlighter-rouge">:libvirt__dhcp_bootp_file</code> - The file to be used for the boot image. Used only when dhcp is enabled.</li> <li><code class="language-plaintext highlighter-rouge">:libvirt__dhcp_bootp_server</code> - The server that runs the DHCP server. U
