How to Transfer files between the Host and Qemu via SSH and NFS

Last week, I wrote a blog post explaining how to copy files to a qemu image by mounting the qemu image in the host. This is only useful if emulated platform does not support networking. If networking is enabled, using SSH (Secure Shell) or NFS (Network File System) is more convenient. Using SSH with Qemu To initiate the SSH connection from qemu, there is actually nothing extra to do as long as you have sshd installed and running on the host. If it is not installed simply run sudo apt-get install openssh-shell on the host. This will install and automatically sshd. To initiate the SSH connection from the host, you’ll have to redirect the ssh port to an unknown port and start qemu as follow (for overo):

sudo qemu-system-arm -M overo -m 256 -drive file=./overo_sd_alip.img,if=sd,cache=writeback -clock unix -serial stdio -device usb-kbd -device usb-mouse -redir tcp:2222::22

1	sudo qemu-system-arm -M overo -m 256 -drive file=./overo_sd_alip.img,if=sd,cache=writeback -clock unix -serial stdio -device usb-kbd -device usb-mouse -redir tcp:2222::22

How to Transfer files between Host and Qemu

I previously posted instructions to install and run nano and ARM Linux Internet Platform (ALIP) distribution images for Overo and Beagleboard on QEMU, If the image support networking, you could use ssh (install dropbear server in qemu) or nfs to transfer files between the host computer and qemu, or even run your program from the NFS share. This should be possible to do that on the Overo emulator since it support Ethernet. However, although I can access Internet, I cannot access the host via ssh as the host is in a private subnetwork (192.168.0.0) and qemu in another (10.0.2.0). We would probably have to enable bridge networking for that but the tun driver is apparently not compiled in ALIP kernel. I’ll look into that later on. [Update: Finally, we don’t need tun/tap to make this work, please read http://www.cnx-software.com/2011/10/02/how-to-transfer-files-between-host-and-qemu-via-ssh-and-nfs/ for details.] Today, I’ll just show how to mount a Qemu […]

Beagleboard Emulator in Ubuntu with Qemu

If you just want to try a program on Beagleboard, but do not want (or have the means) to purchase a board, you may be able to use qemu to emulate the Beagleboard or BeableBoard-xM. I’ll details the instructions to run the Nano build (minimal kernel) and the ARM Linux Internet Platform (ALIP) distribution for Beagleboard on qemu. Please read the full post before starting the installation before there are currently some issues such as no Ethernet support. First, install or update linaro-media-create: sudo add-apt-repository ppa:linaro-maintainers/tools sudo apt-get update sudo apt-get install linaro-image-tools Then download the nano image and omap3 hardware pack: wget http://releases.linaro.org/platform/linaro-n/nano/11.08/nano-n-tar-20110823-1.tar.gz wget http://releases.linaro.org/platform/linaro-n/nano/11.08/hwpack_linaro-omap3_20110823-0_armel_supported.tar.gz Generate the image for qemu: sudo linaro-media-create –image_file beagle_sd.img –dev beagle –binary nano-n-tar-20110823-1.tar.gz –hwpack hwpack_linaro-omap3_20110823-0_armel_supported.tar.gz If you don’t have it already, get the latest qemu-linaro package from Linaro Maintainers PPA: sudo apt-get install qemu-system Check the version is correct: qemu-system-arm -version QEMU emulator version […]

Emulate Gumstix Overo COM with Qemu and Linaro Nano Image

Overa COMs are low cost computer-on-modules (COM) built around OMAP3503 and OMAP3530 depending on the model. Such device can be purchased on gumstix website. However if you just want to try a program on the board, you could use QEMU to emulate the Overo board as follows: Download pre-built image. (nano is a minimal linux ditribution without UI): wget http://releases.linaro.org/images/linaro-n/nano/11.07/overo-nano.img.gz gunzip overo-nano.img.gz Install the qemu tools: sudo add-apt-repository ppa:linaro-maintainers/tools sudo apt-get update sudo apt-get install qemu-user-static qemu-system Run the image: qemu-system-arm -M overo -clock unix -serial stdio -device usb-kbd -drive file=/tmp/overo-nano.img,if=sd,cache=writeback You can also watch the installation in the video below: Source: https://wiki.linaro.org/Resources/HowTo/Qemu-5 Jean-Luc Aufranc (CNXSoft)Jean-Luc started CNX Software in 2010 as a part-time endeavor, before quitting his job as a software engineering manager, and starting to write daily news, and reviews full time later in 2011. www.cnx-software.com

Qemu Linaro Versatile Express Image on Ubuntu 10.10

I’ve installed qemu-linaro and run an ARM image based on the instructions on https://wiki.linaro.org/PeterMaydell/QemuVersatileExpress. I used Ubuntu 10.10 desktop edition. First, install the Linaro images tools: sudo apt-get install linaro-image-tools Download the Linaro release and versatile hardware pack: wget http://releases.linaro.org/platform/linaro-n/nano/alpha-3/linaro-natty-nano-tar-20110302-0.tar.gz wget http://releases.linaro.org/platform/linaro-n/hwpacks/alpha-3/hwpack_linaro-vexpress_20110302-0_armel_supported.tar.gz You can download another hwpack for omap3, i.mx51, pandaboard, beagleboard, ST U8500, etc.. if needed at http://releases.linaro.org/platform/linaro-n/hwpacks/alpha-3/ Download the source, extract it, then configure, build and install qemu linaro: wget http://launchpad.net/qemu-linaro/trunk/2011.03-1/+download/qemu-linaro-0.14.50-2011.03-1.tar.gz tar xzvf qemu-linaro-0.14.50-2011.03-1.tar.gz cd qemu-linaro-0.14.50-2011.03-1 ./configure –prefix=/usr make sudo make install Make sure the prefix is set to /usr in order to overwrite any previous version of Qemu (It installed qemu linaro in /usr/local/ instead in my case). Failure to do so may generate the following error during linaro-media-create: qemu: fatal: cp15 insn ee1d6f70 Instead of compiling qemu, you can install qemu-linaro with apt-get (this will avoid possible version issues between linaro-media-create and qemu): sudo add-apt-repository ppa:linaro-maintainers/tools […]

Emulate an ARM Plaform with QEMU on Ubuntu 10.10

When developing software for embedded systems, you may need to support multiple architectures such as arm, mips, x86, powerpc, alpha etc.. but you may not have the hardware required on hand to test them. This is where QEMU – a processor emulator – comes to the rescue. In a way, QEMU is similar to VirtualBox, VMWare or Citrix Xendeskop except it can support multiple architectures. I’ll show how to run Debian Lenny ARMEL in QEMU on a computer running Ubuntu 10.10 (aka Ubuntu Maverick Meerkat). QEMU (Qemu-kvm) Installation First install qemu-kvm and qemu-kvm-extras (the latter contains qemu-system-arm): sudo apt-get install qemu-kvm qemu-kvm-extras Let’s check qemu version: jaufranc@CNX-TOWER:~/edev$ qemu –version QEMU PC emulator version 0.12.5 (qemu-kvm-0.12.5), Copyright (c) 2003-2008 Fabrice Bellard Debian ARM Installation in QEMU Create a directory to store the required files for the emulator and download the Debian Lenny ARMEL kernel (vmlinuz) and debian installer rootfs (initrd.gz): mkdir […]
