adt-virt-qemu - autopkgtest virtualisation server using QEMU
] image [ro-image ...]
provides an autopkgtest virtualisation server using QEMU.
will be invoked by adt-run
You always need to specify at least one QEMU VM image. If your VM needs more
disks, you can specify arbitrarily many additional images which will be added
does not modify
the given images, but will instead
create a temporary overlay for the primary image, and add all other images as
assumes that you have already prepared a suitable Debian
based QEMU image (see BUILDING IMAGES
below for how to create them).
but you can use any VM which satisfies one of:
- They open a root shell on ttyS1, or
- They have a serial console on ttyS0 where you can log in
(getty or similar) with specified user and password. This will then be
used to start a root shell on ttyS1, to reduce this to the first case and
to not assume that ttyS0 stays operational throughout the whole test.
- -u user | --user=user
User name for running tests that don't require root privileges.
If the VM is not already prepared to start a root shell on ttyS1 this will
be also used for logging in on ttyS0. If this is not root, it must be able
to run sudo without a password to become root for that purpose.
- -p password |
- Password for above user for logging into the VM on ttyS0.
This is necessary if the VM is not already prepared to start a root shell
- -q command |
- QEMU command to run. This defaults to the
qemu-system-* that matches your system architecture.
- -o dir | --overlay-dir=dir
- Directory where the temporary image overlay for the primary
image is created. By default this will happen in a work directory in
/tmp (or $TMPDIR), but you can use this to e. g. ensure that
the overlay is placed on a tmpfs if your /tmp directory is not on
tmpfs. This will greatly increase the speed.
- -c num | --cpus=num"
- Number of (virtual) CPUs in the VM. Default is 1.
- VM RAM size in MiB. Default is 1024, i. e. 1 GiB.
- -d | --debug
- Enable debugging output.
- Pass through arguments to QEMU command; e. g.
If you use lots of options or images, you can put parts of, or the whole command
line into a text file, with one line per option. E. g. you can create a file
with contents like
and then run
adt-run [...] --- adt-virt-qemu @sid-desktop.cfg
The contents of the configuration file will be expanded in-place as if you would
have given its contents on the command line. Please ensure that you don't
between short options and their values, they would become a
part of the argument value.
INPUT, OUTPUT AND EXIT STATUS¶
The behaviour of adt-virt-qemu
is as described by the AutomatedTesting
virtualisation regime specification.
does not run apt-get update
at the start of a package
build, which can cause a build failure if you are using a development series
template. You will need to run apt-get update
in the template yourself
(e. g. using --setup-commands
For Debian you can use vmdebootstrap(8)
to build a suitable image. E. g.
vmdebootstrap --verbose --serial-console --distribution=sid \
--user=adt/adt --size=10000000000 --image=adt-sid.raw
qemu-img convert -O qcow2 adt-sid.raw adt-sid.img
can only create a raw format image; it is recommended to
convert it to qcow2 as that is much smaller (in the order of 700 MB for qcow2
vs. the 10 GB as specified above) and also supports additional features such
as snapshots or compression. You can run that command with setting the
environment variable ADT_APT_PROXY
to a proxy which will be used by apt
in the VM. If you have apt-cacher-ng installed on the host, this will be used
automatically; otherwise you can run e. g.
For Ubuntu, autopkgtest provides adt-buildvm-ubuntu-cloud(1)
to build a
VM based on the Ubuntu cloud images. To create an image for the current
development series and the i386 architecture:
adt-buildvm-ubuntu-cloud -v -a i386
This will produce e. g. adt-trusty-i386-cloud.img.
Run the tests of the libpng source package, using an Ubuntu cloud image:
adt-run libpng --- adt-virt-qemu adt-trusty-i386-cloud.img
