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=64 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 direc- tory. 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. AUTHOR
