Guidelines for choosing a QEMU machine Accurate emulation of existing hardware "lm3s6965evb" (which are both TI Stellaris evaluation boards). We only have two boards which use the M-profile CPU at the moment: "lm3s811evb" and We don't implement so many different machines.Īs well as the more common "A-profile" CPUs (which have MMUs and will run Linux) we also support the Cortex-M3 and Cortex-M4 "M-profile" CPUs (which are microcontrollers used in very embedded boards. The situation for 64-bit ARM is fairly similar, except that Much less about the detail of the hardware.) (Once the kernel has booted, most userspace software cares X86 world where every system looks like a standard PC. This is often surprising for new users who are used to the Run on one machine will not run at all on any other. Typically operating system or firmware images intended to Even with fifty boards QEMUĭoes not cover more than a small fraction of the ARMīecause ARM systems differ so much and in fundamental ways, Then built into machines which can vary still further even "system-on-chip" (SoC) designs created by many differentĬompanies with different devices, and these SoCs are So many is that ARM hardware is much more widely varying QEMU has generally good support for ARM guests. 1.1.3 Example for using the canon-a1100 machine.1.1.2.1 Guest kernel configuration for the virt machine.1.1.2 Generic ARM system emulation with the virt machine.1.1.1 Accurate emulation of existing hardware.1.1 Guidelines for choosing a QEMU machine.You should connect with a VNC client to 127.0.0. The last line will tell you where to connect, for example if the output is: 127.0.0.1:1 Then restart your VM with virsh vmname stop VNC accessĪlternatively you can enable a VNC console by adding the following to /etc/libvirt/qemu/ vm-name.xml, before the end of section: Now you know how to run a VM headless in qemu-kvm-libvirtd. Now is just mater of connect to the virtual machine via ssh: I have to add options to ssh, because is different from the debian 6 days I’m pretty sure there are better ways to do it, but I did it with arp: /24 is the default network for my virtual machines So, I’ve got my VM running… how to connect to do something with that? First I need to know the IP² for this VM. The get the options for the -os-variant switch run: virt-install -osinfo listįor example, I’m running an ancient Debian distribution: You can add the switch – -noautoconsole to run on background. With the virt-install command you can import a disk image using this command line: virt-install -import -name -memory -vcpus -disk ,bus=sata -os-variant -network default a VM is running If not, you can start it with systemctl start libvirtd. My server happens to work with Debian 11, so I’m installing qemu, kvm and all the stuff with apt-get: apt-get install qemu-kvm libvirt-clients virtinst bridge-utils cpu-checker that’s some dependenciesĪfter the installation make sure libvirtd is running systemctl status libvirtd libvirtd status In order to run the virtual machine with qemu we need to install the virtualization packages. Launching the VM headless Software needed By the way, if for some reason you need to deploy some old software you can find Debian CD/DVD images here. The solution? I’ve created – with gnome-boxes of course – a Debian 6.0.10 (from 2014) in my own PC, then uploaded the disk image to the server and launch there the virtual machine. On the other hand, I don’t have much time to learn how to do everything from the command line¹. My idea is do not install those frontends on the server, and launch the virtual machine by command line. I also have some time working with gnome-boxes, sometimes alternating with virt-manager. The idea was to install the minimal amount of extra software on the server. So this is how to run a VM headless in QEMU-KVM-libvirt-etc. Then I though in create a Virtual Machine. I couldn’t even compile those packages for our linux in the new server. A client asked me to find a way to keep running an ancient system (from 10+ years ago) in a new server.
