DESCRIPTION
qemubuilder Executes the specified pbuilder operation with qemu
COMMANDS
Most commands
imitate pbuilder, see pbuilder manual for details.
--create, create
Create the base.qemu image.
--update, update, up, u
Update the base.qemu image.
--build, build, b
Build a package given a .dsc file
--login, login, l
Start a session within the base.qemu.
--execute, execute, e
Execute a command within the base.qemu.
--dumpconfig, dumpconfig
Dump configuration information, used for debugging.
OPTIONS
Most options
are the same as pbuilder, except for the following which are
handled specially.
--arch-diskdevice sd/hd
Specify whether the disk device inside the virtual machine is called /dev/sda or /dev/hda. The possible values are ’sd’ and ’hd’.
--smp 2
The option passed to SMP.
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.
|
SMP=2 |
The SMP option for qemu. |
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.
