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/basetest.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.
