NAME

       sbuild-qemu-boot - Boot a VM using a QEMU image

SYNOPSIS

       sbuild-qemu-boot    [-h]    [--read-write]   [--snapshot]   [--shared-dir]   [--arch=ARCH]
       [--ram-size=MiB] [--cpus=CPUs] [--ssh-port=PORT] [--noexec] IMAGE

DESCRIPTION

       sbuild-qemu-boot boots a QEMU VM using IMAGE into a console. The  image  is  in  read-only
       mode by default, as the goal is to support experimentation.

       The architecture is auto-guessed by stripping any file suffix and then splitting the image
       name  on  dashes  ``-'',  and  finally  by  looking  for  a  Debian   architecture   name.
       sid-amd64.img,  amd64-temporary.image  or even just amd64 would all be assumed to be amd64
       images, but not amd64.rebuild-tests.img. If this guesses wrong, use the --arch option.

       Note that you might need to invoke stty(1) within the VM to  match  your  host  terminal's
       settings.

OPTIONS

       -h, --help
              Show this help message and exit.

       --read-write
              Write changes back to the image, instead of using the image in read-only mode.

       --snapshot
              Create  a  snapshot  of  the  image  before changing it. Useful for reproducibility
              purposes. Ignored if the image is not booted  in  read-write  mode,  which  is  the
              default.

       --shared-dir
              Share this directory on the host with the guest. This will only work when the image
              was created with sbuild-qemu-create(1).

       --arch=ARCH
              Architecture to use (instead of attempting to auto-guess).

       --ram-size=MiB
              VM memory size in MB. Default: 2048

       --cpus=CPUs
              VM CPU count. Default: 2

       --ssh-port=PORT
              Forward local port PORT to port 22 within the guest. Package openssh-server must be
              installed within the guest for this to be useful.

       --boot=auto,bios,efi,ieee1275,none
              How  to  boot the image. Default is BIOS on amd64 and i386, EFI on arm64 and armhf,
              and IEEE1275 on ppc64el.

       --noexec
              Don't actually do anything. Just print the command string that would  be  executed,
              and then exit.

EXAMPLES

       $ sbuild-qemu-boot --shared-dir /tmp/foo unstable-autopkgtest-amd64.img

       This  will update the image unstable-autopkgtest-amd64.img in the current directory. If no
       such file exists there, then $IMAGEDIR/unstable-autopkgtest-amd64.img is tried.

ENVIRONMENT

       If $IMAGEDIR is unset, then ~/.cache/sbuild is used.
