Now, we need to set up a network bridge interface. You can verify this using:Īlso make sure that /dev/net/tun exists. The host system needs to have TUN/TAP networking enabled (CONFIG_TUN=m or CONFIG_TUN=y). In recent kernels, this requires CAP_NET_ADMIN capability. The networking setup uses host TAP devices to connect to QEMU. Networking is setup between the host system and the QEMU guest to allow the guest to get its IP address using DHCP. However that may prevent you from using yum to install new packages on your Fedora-ARM guest. You can skip this section if you are going to use a local loopback device for your root file system. If you are running Fedora 7/8, you can just install qemu using yum. Use virsh define nameOfXMLFile to define the new VM from the modified XML file.Change the image filename (in the source tag in the devices section) to point to the new image file you just created.Change the UUID (you can use uuidgen to generate a new one).Edit the XML, making the following changes:.Make a new copy of the arm1.img file under a different name in /var/lib/libvirt/images.Use ssh instead of the console to access a shell on the VM (faster, and more flexible)įor each additional ARM VM you wish to create:.You can get a DHCP address for the VM using dhclient eth1, or set up a static IP configuration. The initial root password for the ARM VM image is fedoraarm. These steps install libvirt and related tools, if not installed already, plus the ARM emulator, and then start the libvirt daemon: Installing and starting the virtualization software Here is a quick-start guide to setting up ARM QEMU emulation under libvirt management: At the tool level, it provides the virsh virtualization shell as well as the virt-manager GUI tool for command-line VM management (plus additional tools).īy using libvirt to manage ARM VMs, you can leverage its capabilities (such as domain autostart, network setup with NAT and DHCP, and console disconnect/reconnect), and manage your ARM and x86 VMs in a consistent manner. Libvirt is a virtualization management framework and toolkit. The host's networking can then be configured to get its IP address using DHCP. The QEMU system is set up to get its root file system from a local loopback block device or over NFS from the host system (requires networking between the host system and the QEMU guest). We assumes that you can run commands as root (or using sudo) whenever necessary. Although we have tested this on Fedora 12, most of the process should work on any other Linux system as well. The howto describes a process to get the Fedora-ARM distribution running under QEMU. This provides a convenient platform to try out the distribution as well as for development and customization. QEMU is a well-known emulator that supports ARM platforms, and can be used to run the Fedora-ARM distribution.
