bento/ubuntu-26.04 libvirt fails to boot

[matuskosut]

Version

bento/ubuntu-26.04                 (libvirt, 202606.01.0, (amd64))

Environment

Ubuntu 24.04 / vagrant 2.4.9-1 / vagrant-libvirt 0.12.2

Scenario

The default box simply created by vagrant init seems to fail to boot. The same t

Steps to Reproduce

Create the most simple init box and then try to start it

vagrant init bento/ubuntu-26.04
vagrant up --provider libvirt

Expected Result

expecting the VM to boot up

Actual Result

is this on a mac or linux host? You may have to set a Primary ~/.vagrant.d/Vagrantfile to set some defaults. Looking at the settings it's using default bios, ps2, etc... for booting the machine. All the boxes for bento are now built as UEFI based virtual machines. This also requires usb controller and keyboard/mouse to be usb based xhci controller.

Since I'm working on mac-mini systems for the builds I had to had my vagrant-libvirt plugin a little and use this configuration file to make it all work after the box is built. Copilot AI was able to help me set it all up.

% cat ~/.vagrant.d/Vagrantfile 
# Global Vagrant configuration for macOS (x86_64, Intel)
Vagrant.configure("2") do |config|
  # libvirt: qemu:///session with user-mode SLIRP networking (no virbr0 bridge needed)
  config.vm.provider :libvirt do |libvirt|
    libvirt.uri = "qemu:///session"
    libvirt.driver = "qemu"
    libvirt.mgmt_attach = false
    libvirt.qemu_use_agent = true
    libvirt.cpu_mode = "host-model"
    # Use q35 chipset (PCIe) for UEFI compatibility
    libvirt.machine_type = "q35"
    # UEFI firmware — box is built with GPT+EFI, SeaBIOS cannot boot it
    libvirt.loader = "/usr/local/share/qemu/edk2-x86_64-code.fd"
    libvirt.nvram = "/tmp/edk2-x86_64-vars.fd"
    libvirt.qemu_args = [
      { value: "-netdev" },
      { value: "user,id=net0,hostfwd=tcp::22222-:22" },
      { value: "-device" },
      { value: "virtio-net-pci,netdev=net0,addr=0x10" },
    ]
  end
  # vagrant-qemu: x86_64 overrides (defaults are aarch64/ARM for Apple Silicon)
  # ssh_port must match config.ssh.port below
  config.vm.provider :qemu do |qemu|
    qemu.qemu_dir = "/usr/local/share/qemu"
    qemu.arch = "x86_64"
    qemu.machine = "q35,accel=hvf,smm=off"
    qemu.cpu = "host"
    qemu.net_device = "virtio-net-pci"
    qemu.ssh_port = "22222"
  end
  config.ssh.host = "127.0.0.1"
  config.ssh.port = 22222
  # Disable default synced folder - not supported with SLIRP/qemu session networking
  config.vm.synced_folder ".", "/vagrant", disabled: true
end

I'd also make sure you are on the latest versions of the software, the box description should have the information on the versions of all the software that was used to build the boxes.

I am running on Ubuntu, listed versions above in the description

Based on your Vagrantfile settings I was able to figure out my settings and then boot it successfully:

# -*- mode: ruby -*-
# vi: set ft=ruby :

require 'fileutils'

# sudo apt install ovmf
OVMF_CODE = "/usr/share/OVMF/OVMF_CODE_4M.fd"
OVMF_VARS = "/usr/share/OVMF/OVMF_VARS_4M.fd"

Vagrant.configure("2") do |config|
  config.vm.box = "bento/ubuntu-26.04"

  ["node1"].each do |hostname|
    config.vm.define hostname do |node|
      node.vm.hostname = hostname

      # Create NVRAM vars for each VM (if host is rebooted machine needs to be recreated)
      nvram = "/tmp/.vagrant/nvram/#{hostname}_VARS.fd"
      FileUtils.mkdir_p(File.dirname(nvram))
      FileUtils.cp(OVMF_VARS, nvram) unless File.exist?(nvram)

      node.vm.provider :libvirt do |libvirt|

        # -- Need to force KVM
        libvirt.driver = "kvm"

        # -- UEFI firmware
        libvirt.loader = OVMF_CODE
        libvirt.nvram = nvram

        # -- Resources
        libvirt.memory = 2048
        libvirt.cpus = 2
      end
    end

  end

  config.vm.synced_folder ".", "/vagrant", disabled: true
end

Is there something that could be change in box to make it work by default?

[Stromweld]

Honestly I'm not sure. That would take a bit more research in what may have changed with Ubuntu 26.04. In the past I believe it was good about supporting uefi and bios booting with the same install. I switched to default all the packer build setting to uefi last year so this isn't the first box to get it.

[matuskosut]

adding these as potentially related:

• Include UEFI loader and nvram in box vagrant-libvirt/vagrant-libvirt#1753
• libvirt builds always use EFI, even on qemu_efi_boot=false #1641
