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.
