adt-virt-qemu - autopkgtest virtualisation server using QEMU
adt-virt-qemu [options] image [ro-image ...]
adt-virt-qemu provides an autopkgtest virtualisation server using QEMU. Normally adt-virt-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 in order. adt-virt-qemu does not modify the given images, but will instead create a temporary overlay for the primary image, and add all other images as read-only.
adt-virt-qemu 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=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 on ttyS1. -q command | --qemu-command=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. --ram-size=MiB VM RAM size in MiB. Default is 1024, i. e. 1 GiB. -d | --debug Enable debugging output.
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 sid-desktop.cfg with contents like -utestuser -ps3kr1t --ram-size=4096 /home/bob/autopkgtest/sid-desktop.img 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 place spaces 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.
adt-run 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).
Debian For Debian you can use vmdebootstrap(8) to build a suitable image. E. g. for unstable: vmdebootstrap --verbose --serial-console --distribution=sid \ --customize=/usr/share/autopkgtest/adt-setup-vm \ --user=adt/adt --size=10000000000 --image=adt-sid.raw qemu-img convert -O qcow2 adt-sid.raw adt-sid.img rm adt-sid.raw vmdebootstrap 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. E. g. if you have apt-cacher-ng installed on the host, you can run ADT_APT_PROXY=http://10.0.2.2:3142 vmdebootstrap [...] Ubuntu 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
adt-run(1), adt-virt-schroot(1), adt-virt-lxc(1), adt-buildvm-ubuntu-cloud(1), vmdebootstrap(8), /usr/share/doc/autopkgtest/.
