       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

       -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.

              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


       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.


       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).


       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= vmdebootstrap [...]

       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

              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/.
