| This section covers the process of setting up QEMU guest networking. Two different processes will be described. //Network Address Translation mode (NAT)// is the first and recommended way to get a functional network in QEMU guests. The second is //bridged mode//. NAT mode does not allow direct access to the Slackware x86 host's physical network and bridged mode does. It is best to use bridged mode if you plan on doing any more advanced network operations that require full access to the host and the host's physical network. **Most users will want to use NAT mode.** | Existen muchas formas diferentes para configurar la red de invitados para QEMU. Este documento solo cubrirá las funcionalidades de QEMU para que Slackware ARM arranque. Refiérase a las paginas del manual o [[https://www.qemu.org/documentation/ | a la documentación de QEMU]] si necesitas una explicación más detallada. |

| There are many different ways to configure QEMU guest networking. This document will only cover the QEMU functionality required to boot Slackware ARM. Refer to the QEMU man pages or the [[https://www.qemu.org/documentation/ | QEMU documentation]] if you need further explanation. | |

| <note warning>Later on when you boot the Slackware ARM installer in QEMU you may need to modify the **txqueuelen** for your network interfaces. This is because large Slackware packages time out while being downloaded from the NFS share on the host. This happens because QEMU emulation is very slow. The NFS daemon on your host machine occasionally shuts down the network socket before large packages (rust, kernel-firmware, etc) finish being copied to the SD Card. Setting the txqueuelen to **10000** for all network interfaces should be sufficient to prevent this anomaly. The following command seems to resolve this issue: | <note warning>Later on when you boot the Slackware ARM installer in QEMU you may need to modify the **txqueuelen** for your network interfaces.

| ==== QEMU NAT Mode Networking ==== | ==== Modo de red NAT para QEMU ==== |
| NAT mode does not require any additional configuration on the Slackware x86 host machine or in the QEMU guest machine. Here is a shortened example of a QEMU guest being launched with NAT mode networking: | El modo NAT no requiere una configuración adicional sobre una máquina Slackware x86 o en la máquina invitada QEMU. |
| | Aquí hay un ejemplo abreviado de un invitado de QEMU que está siendo lanzado con el modo de red NAT: |
| <code> | <code> |
| # cd /export/armhost | # cd /export/armhost |

| With NAT mode enabled, QEMU launches a virtual network of 10.0.2.0/24. The QEMU guest will be assigned the IP address 10.0.2.15. The guest can access the Slackware x86 host at 10.0.2.2 and the QEMU DNS server runs at 10.0.2.3. QEMU does not have direct access to the host's Local Area Network. This means that the QEMU guest isn't assigned a physical IP address by your router DHCP service. You will not be able to ping the QEMU guest from the host machine but the guest should be able to ping the host machine at 10.0.2.2. The QEMU guest should be able to access the internet and communicate with the host machine. | With NAT mode enabled, QEMU launches a virtual network of 10.0.2.0/24.

| The best way to set up a bridged network interface for QEMU is with the provided helper script, rc.local-additions. If you choose to take this route, you need to disable the NetworkManager service. NetworkManager comes with Slackware, but it is not developed by Slackware. As a result, the process of configuring a bridge with NetworkManager is not supported in this guide. | The best way to set up a bridged network interface for QEMU is with the provided helper script, rc.local-additions.
