[Qemu-devel] [PATCH v10 00/13] tests: Add VM based build tests (for non-x86_64 and/or non-Linux)

[Fam Zheng]

v10: Rebase - trivial conflict in docker Makefile.include.
     Specify bash in shebang. [Eric]
     Tweaks in README and pub key comment. [Eric]
     Clean up $1.list if tar failed. [Eric]
     Set locale in cloud-init for ubuntu image.

v9: Don't use 'set -e' in archive-source.sh. [Eric]
    Add tests/keys/README. [Eric]
    Fix direct invocation of ./netbsd etc. [Alex]
    Add a note about test image well-known ssh key. [Eric]

Build tests in one 32 bit Linux guest and three BSD images are defined in this
series. This is a more managable way than the manually maintained virtual
machines in patchew. Also, one big advantage of ephemeral VMs over long running
guests is the reduced RAM usage of host, which makes it possible to have one
host test all these BSD variants and probably more.

The BSD guest templates are manually prepared following

https://wiki.qemu.org/Hosts/BSD

as it is not easy to automate. (The ideal approach is like the ubuntu.i386
script, which configures the guest on top of an official released image, fully
automatically.)

Need for help: "gmake check" in the added OpenBSD image fails with -ENOMEM
errors, even if I change "-m 2G" to "-m 8G" when starting VM. Ideas? And there
is a warning from ./configure about OpenBSD going to be unsupported in coming
releases, is it still the case?

[Qemu-devel] [PATCH v10 05/13] tests: Add vm test lib

[Fam Zheng]

This is the common code to implement a "VM test" to

  1) Download and initialize a pre-defined VM that has necessary
  dependencies to build QEMU and SSH access.

  2) Archive $SRC_PATH to a .tar file.

  3) Boot the VM, and pass the source tar file to the guest.

  4) SSH into the VM, untar the source tarball, build from the source.

+=== VM test suite to run build in guests ===
+
+== Intro ==
+
+This test suite contains scripts that bootstrap various guest images that have
+necessary packages to build QEMU. The basic usage is documented in Makefile
+help which is displayed with "make vm-test".
+
+== Quick start ==
+
+Run "make vm-test" to list available make targets. Invoke a specific make
+command to run build test in an image. For example, "make vm-build-freebsd"
+will build the source tree in the FreeBSD image. The command can be executed
+from either the source tree or the build dir; if the former, ./configure is not
+needed. The command will then generate the test image in ./tests/vm/ under the
+working directory.
+
+Note: images created by the scripts accept a well-known RSA key pair for SSH
+access, so they SHOULD NOT be exposed to external interfaces if you are
+concerned about attackers taking control of the guest and potentially
+exploiting a QEMU security bug to compromise the host.
+
+== QEMU binary ==
+
+By default, qemu-system-x86_64 is searched in $PATH to run the guest. If there
+isn't one, or if it is older than 2.10, the test won't work. In this case,
+provide the QEMU binary in env var: QEMU=/path/to/qemu-2.10+.
+
+== Make jobs ==
+
+The "-j$X" option in the make command line is not propagated into the VM,
+specify "J=$X" to control the make jobs in the guest.
+
+== Debugging ==
+
+Add "DEBUG=1" and/or "V=1" to the make command to allow interactive debugging
+and verbose output. If this is not enough, see the next section.
+
+== Manual invocation ==
+
+Each guest script is an executable script with the same command line options.
+For example to work with the netbsd guest, use $QEMU_SRC/tests/vm/netbsd:
+
+    $ cd $QEMU_SRC/tests/vm
+
+    # To bootstrap the image
+    $ ./netbsd --build-image --image /var/tmp/netbsd.img
+    <...>
+
+    # To run an arbitrary command in guest (the output will not be echoed unless
+    # --debug is added)
+    $ ./netbsd --debug --image /var/tmp/netbsd.img uname -a
+
+    # To build QEMU in guest
+    $ ./netbsd --debug --image /var/tmp/netbsd.img --build-qemu $QEMU_SRC
+
+    # To get to an interactive shell
+    $ ./netbsd --interactive --image /var/tmp/netbsd.img sh
+
+== Adding new guests ==
+
+Please look at existing guest scripts for how to add new guests.
+
+Most importantly, create a subclass of BaseVM and implement build_image()
+method and define BUILD_SCRIPT, then finally call basevm.main() from the
+script's main().
+
+  - Usually in build_image(), a template image is downloaded from a predefined
+    URL. BaseVM._download_with_cache() takes care of the cache and the
+    checksum, so consider using it.
+
+  - Once the image is downloaded, users, SSH server and QEMU build deps should
+    be set up:
+
+    * Root password set to BaseVM.ROOT_PASS
+    * User BaseVM.GUEST_USER is created, and password set to BaseVM.GUEST_PASS
+    * SSH service is enabled and started on boot,
+      $QEMU_SRC/tests/keys/id_rsa.pub is added to ssh's "authorized_keys" file
+      of both root and the normal user
+    * DHCP client service is enabled and started on boot, so that it can
+      automatically configure the virtio-net-pci NIC and communicate with QEMU
+      user net (10.0.2.2)
+    * Necessary packages are installed to untar the source tarball and build
+      QEMU
+
+  - Write a proper BUILD_SCRIPT template, which should be a shell script that
+    untars a raw virtio-blk block device, which is the tarball data blob of the
+    QEMU source tree, then configure/build it. Running "make check" is also
+    recommended.

This relies on 'test ... -o ...' which is non-portable.  It "works"
because there is no possible ambiguity in the contents of $PIPESTATUS
that could cause a different parse of the test arguments, but I tend to
discourage any use of -a/-o inside test on principle.  Sadly, writing:

if test ${PIPESTATUS[0]} -ne 0 || test $? -ne 0

has a flaw that $? is no longer what you want, at which point you would
have to introduce a temporary variable.  But we're using bash, so you
can instead write this as:

if test "${PIPESTATUS[@]}" != "0 0"; then

At this point, $1.list has been created, even if commands failed...

...but this exits without cleanup.  If we really want it cleaned no
matter what, it's probably better to do:

trap "status=$?; rm -f "$1".list; exit \$status" 0 1 2 3 15

earlier than anything that can create the file.

Umm, $statue is not the same as $status.

While testing v10, I got:

$ make vm-build-freebsd
...
    VM-BUILD freebsd
./scripts/archive-source.sh: line 48: test: -ne: unary operator expected
ar: warning: creating libfdt/libfdt.a

At least the archive-source.sh warning is part of your series, and worth
fixing.

Hmm, with exactly this line here I get something like:

./scripts/archive-source.sh: line 36: test: too many arguments

But with

    if test "${PIPESTATUS[0]} ${PIPESTATUS[1]}" != "0 0"; then

it seems to work fine. What is the magic here?

D'oh - [@] causes word splitting (same as "$@"); we want [*] instead:

if test "${PIPESTATUS[*]}" != "0 0";

or that's a manual way of spelling the auto-array-concatenation that you
get with [*].
