7789331b03 tests/qtest: Don't print messages from query instances
Now that we can query more than one binary, the "starting QEMU..."
message can get a little noisy. Mute those messages unless we're
running with --verbose.

Only affects qtest_init() calls from within libqtest. The tests
continue to output as usual.

6c6d2330a0 tests/qtest/migration: Allow user to specify a machine type
Accept the QTEST_QEMU_MACHINE_TYPE environment variable to take a
machine type to use in the tests.

The full machine type is recognized (e.g. pc-q35-8.2). Aliases
(e.g. pc) are also allowed and resolve to the latest machine version
for that alias, or, if using two QEMU binaries, to the latest common
machine version between the two.

5050ad2a38 tests/qtest/migration: Support more than one QEMU binary
We have strict rules around migration compatibility between different
QEMU versions but no test to validate the migration state between
different binaries.

Add infrastructure to allow running the migration tests with two
different QEMU binaries as migration source and destination.

The code now recognizes two new environment variables
QTEST_QEMU_BINARY_SRC and QTEST_QEMU_BINARY_DST. In the absence of
either of them, the test will use the QTEST_QEMU_BINARY variable. If
both are missing then the tests are run with single binary as
previously.

The machine type is selected automatically as the latest machine type
version that works with both binaries.

Usage (only one of SRC|DST is allowed):

QTEST_QEMU_BINARY_SRC=../build-8.2.0/qemu-system-x86_64 \
QTEST_QEMU_BINARY=../build-8.1.0/qemu-system-x86_64 \
./tests/qtest/migration-test

3cb9c6553b tests/qtest/migration: Specify the geometry of the bootsector
We're about to enable the x86_64 tests to run with the q35 machine,
but that machine does not work with the program we use to dirty the
memory for the tests.

The issue is that QEMU needs to guess the geometry of the "disk" we
give to it and the guessed geometry doesn't pass the sanity checks
done by SeaBIOS. This causes SeaBIOS to interpret the geometry as if
needing a translation from LBA to CHS and SeaBIOS ends up miscomputing
the number of cylinders and aborting due to that.

The reason things work with the "pc" machine is that is uses ATA
instead of AHCI like q35 and SeaBIOS has an exception for ATA that
ends up skipping the sanity checks and ignoring translation
altogether.

Workaround this situation by specifying a geometry in the command
line.

a3c0ebc9b0 tests/qtest: Introduce qtest_resolve_machine_alias
The migration tests are being enhanced to test migration between
different QEMU versions. A requirement of migration is that the
machine type between source and destination matches, including the
version.

We cannot hardcode machine types in the tests because those change
with each release. QEMU provides a machine type alias that has a fixed
name, but points to the latest machine type at each release.

Add a helper to resolve the alias into the exact machine
type. E.g. "-machine pc" resolves to "pc-i440fx-8.2"

3dc35470c8 tests/qtest: migration-test: Add tests for file-based migration
Add basic tests for file-based migration.

Note that we cannot use test_precopy_common because that routine
expects it to be possible to run the migration live. With the file
transport there is no live migration because we must wait for the
source to finish writing the migration data to the file before the
destination can start reading. Add a new migration function
specifically to handle the file migration.

97970dae53 hw/ufs: Fix code coverity issues
Fixed four ufs-related coverity issues.

The coverity issues and fixes are as follows

1. CID 1519042: Security issue with the rand() function
Changed to use a fixed value (0xab) instead of rand() as
the value for testing

2. CID 1519043: Dereference after null check
Removed useless (redundant) null checks

3. CID 1519050: Out-of-bounds access issue
Fix to pass an array type variable to find_first_bit and
find_next_bit using DECLARE_BITMAP()

4. CID 1519051: Out-of-bounds read issue
Fix incorrect range check for lun

Fix coverity CID: 1519042 1519043 1519050 1519051

b6aed193e5 python: use vm.cmd() instead of vm.qmp() where appropriate
In many cases we just want an effect of qmp command and want to raise
on failure.  Use vm.cmd() method which does exactly this.

The commit is generated by command

  git grep -l '\.qmp(' | xargs ./scripts/python_qmp_updater.py

And then, fix self.assertRaises to expect ExecuteError exception in
tests/qemu-iotests/124

Use a shorter name. We are going to move in iotests from qmp() to
command() where possible. But command() is longer than qmp() and don't
look better. Let's rename.

You can simply grep for '\.command(' and for 'def command(' to check
that everything is updated (command() in tests/docker/docker.py is
unrelated).
