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'.

 

OPTIONS

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

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=64
memory size to use in qemu session, in MB.

ARCH_DISKDEVICE=hd

The architecture-specific disk device specifier. Most arches use sd, except for i386 and amd64, which 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=64

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.
