NAME

   qemubuilder - a pbuilder wrapper for qemu.

SYNOPSIS

   qemubuilder [commands] [options]

DESCRIPTION

   qemubuilder Executes the specified pbuilder operation with qemu

COMMANDS

   Most commands imitate pbuilder, see pbuilder manual for details.

   --create

          Create the base.qemu image.

   --update

          Update the base.qemu image.

   --build .dsc-file

          Build a package given a .dsc file

   --login

          Start a session within the base.qemu.

   --execute

          Execute a command within the base.qemu.

   --dumpconfig

          dump configuration information.

   --arch-diskdevice sd/hd

          specify whether disk device inside the virtual machine is called
          /dev/sda or /dev/hda. The possible value is 'sd' or 'hd'.

   --smp 2

          The option passed to SMP.

OPTIONS

   Most options are the same as pbuilder, except for the  following  which
   are handled specially.

   SMP 2

          The SMP option for qemu.

          I don't think I can support bind-mounts in qemu.

          Documentation here should be updated according to what's defined
          in parameter.c, but it isn't.

CONFIGURATION FILES

   qemubuilder reads the following configuration files per default.

   /usr/share/pbuilder/pbuilderrc
          Application default, not to be changed.

   /etc/pbuilderrc
          System-wide default.

   ~/.pbuilderrc
          User default

   anything specified with --configfile option
          Additional configuration at runtime.

CONFIGURATION FILE OPTIONS

   The possible configuration options are as follows.  Others are ignored.

   DISTRIBUTION=distribution

   BUILDRESULT=directory

   BUILDPLACE=directory

   BASEPATH=path

   MIRRORSITE=http://mirror

   KERNEL_IMAGE=vmlinuz
          Linux kernel to use.

   INITRD=initrd
          initrd to use.

   ARCHITECTURE=arch

          The target architecture.

          You can also use ARCH=arch for compatibility with 0.60 or older.

   MEMORY_MEGS=256
          memory size to use in qemu session, in MB.

   ARCH_DISKDEVICE=hd

          The architecture-specific disk device specifier. Most arches use
          sd  these  days.  The only exceptions were i386 and amd64, which
          used to use hd.

EXAMPLES

   qemubuilder --create
          Create a base.qemu image.

   qemubuilder --update
          Update the base.qemu image.

   qemubuilder --build test_0.1.dsc
          Build the package specified in  dsc  file,  with  the  base.qemu
          image.

   pdebuild --pbuilder qemubuilder
          Run  qemubuilder  --build  against  the  current directory.  The
          current directory should be an extracted Debian  source  package
          directory.

          Edit  /etc/pbuilderrc  to  have PDEBUILD_PBUILDER=qemubuilder to
          make this the default behavior for pdebuild.

   qemubuilder      --create      --distribution      sid       --basepath
   /var/cache/pbuilder/base-test.qemu
          Create a base.qemu image with the path /var/cache/pbuilder/base-
          test.qemu and distribution sid.

   Example pbuilderrc for i386

          KERNEL_IMAGE=vmlinuz-2.6.18-4-k7
          INITRD=initrd.img-2.6.18-4-k7
          ARCHITECTURE=i386
          BASEPATH=/home/dancer/tmp/base-i386.qemu
          MEMORY_MEGS=256

          Note. INITRD may or may not be required for your system.  Debian Installer
          initrd may or may not work depending on which one you choose, use the
          one from an installed system.

   CAVEATS

          Note that for mirror specification, http://localhost/debian/ usually
          doesn't work, it will be searching for files on the virtual machine
          itself, not the host OS.
