Daniel P. BerrangéandAlex Bennée dfaaacc67f tests/docker: fix mistakes in ubuntu package lists
librados-dev is not required by QEMU directly, only librbd-dev.

glusterfs-common is not directly needed by QEMU.

QEMU uses ncursesw only on non-Windows hosts.

The clang package is clang 10.

flex and bison are not required by QEMU.

Standardize on nmap ncat implementation to match Fedora/CentOS.

Remove vim since it is not a build pre-requisite and no other containers
include it.

Daniel P. BerrangéandAlex Bennée 1d3a56d7f1 tests/docker: fix mistakes in centos package lists
mesa-libEGL-devel is not used in QEMU at all, but mesa-libgbm-devel is.

spice-glib-devel is not use in QEMU at all, but spice-protocol is.
We also need the -devel package for spice-server, not the runtime.

There is no need to specifically refer to python36, we can just
use python3 as in other distros.

Daniel P. BerrangéandAlex Bennée 888673bbb9 tests/docker: remove FEATURES env var from templates
In preparation for switching to auto-generated dockerfiles, remove the
FEATURES env variable. The equivalent functionality can be achieved in
most cases by just looking for existance of a binary.

The cases which don't correspond to binaries are simply dropped because
configure/meson will probe for any requested feature anyway.

Daniel P. BerrangéandAlex Bennée 1ae2786c7c tests/docker: use explicit docker.io registry
It is good practice to use an explicit registry for referencing the base
image. This is because some distros will inject their own registries
into the search path. For example registry.fedoraproject.org comes ahead
of docker.io. Using an explicit registry avoids wasting time querying
multiple registries for images that they won't have.

Daniel P. BerrangéandAlex Bennée 102cd5c294 tests/docker: use project specific container registries
Since Docker Hub has started to enforce pull rate limits on clients, it
is preferrable to use project specific container registries where they
are available. Fedora and OpenSUSE projects provide registries.

The images in these registries are also refreshed on a more regular
basis than the ones in docker hub, so the package update should
generally be faster.

While CentOS also has a registry it is considerably outdated compared
to docker.io, and also only provides x86 images, while docker.io images
are multi-arch.

Daniel P. BerrangéandAlex Bennée 0e103a65ba gitlab: support for FreeBSD 12, 13 and macOS 11 via cirrus-run
This adds support for running 4 jobs via Cirrus CI runners:

 * FreeBSD 12
 * FreeBSD 13
 * macOS 11 with default XCode
 * macOS 11 with latest XCode

The gitlab job uses a container published by the libvirt-ci
project (https://gitlab.com/libvirt/libvirt-ci) that contains
the 'cirrus-run' command. This accepts a short yaml file that
describes a single Cirrus CI job, runs it using the Cirrus CI
REST API, and reports any output to the console.

In this way Cirrus CI is effectively working as an indirect
custom runner for GitLab CI pipelines. The key benefit is that
Cirrus CI job results affect the GitLab CI pipeline result and
so the user only has look at one CI dashboard.

puts the -I path without the trailing '/capstone' suffix. This breaks
the ability to "#include <capstone.h>". Upstream and most distros have
fixed this, but a few stragglers remain, notably FreeBSD.

CONFIG_LINUX_IO_URING is not included in config-host.mak and therefore is
not usable in "when" clauses.  Check the availability of the library,
which matches the condition for the non-stubbed version block/io_uring.c.

At this point, the difference between libraries that have config-host.mak
entries and those that do not is quite confusing.  The remaining ~dozen
should be converted in 6.2.

steps.

The playbook introduced here covers the Linux distributions and
has been primarily tested on OS/machines that the QEMU project
has available to act as runners, namely:

 * Ubuntu 20.04 on aarch64
 * Ubuntu 18.04 on s390x

But, it should work on all other Linux distributions.  Earlier
versions were tested on FreeBSD too, so chances of success are
high.

Cleber RosaandAlex Bennée b38a04f71f Jobs based on custom runners: documentation and configuration placeholder
As described in the included documentation, the "custom runner" jobs
extend the GitLab CI jobs already in place.  One of their primary
goals of catching and preventing regressions on a wider number of host
systems than the ones provided by GitLab's shared runners.

This sets the stage in which other community members can add their own
machine configuration documentation/scripts, and accompanying job
definitions.  As a general rule, those newly added contributed jobs
should run as "non-gating", until their reliability is verified (AKA
"allow_failure: true").

Peter XuandDr. David Alan Gilbert 63268c4970 migration: Move bitmap_mutex out of migration_bitmap_clear_dirty()
Taking the mutex every time for each dirty bit to clear is too slow, especially
we'll take/release even if the dirty bit is cleared.  So far it's only used to
sync with special cases with qemu_guest_free_page_hint() against migration
thread, nothing really that serious yet.  Let's move the lock to be upper.

There're two callers of migration_bitmap_clear_dirty().

For migration, move it into ram_save_iterate().  With the help of MAX_WAIT
logic, we'll only run ram_save_iterate() for no more than 50ms-ish time, so
taking the lock once there at the entry.  It also means any call sites to
qemu_guest_free_page_hint() can be delayed; but it should be very rare, only
during migration, and I don't see a problem with it.

For COLO, move it up to colo_flush_ram_cache().  I think COLO forgot to take
that lock even when calling ramblock_sync_dirty_bitmap(), where another example
is migration_bitmap_sync() who took it right.  So let the mutex cover both the
ramblock_sync_dirty_bitmap() and migration_bitmap_clear_dirty() calls.

It's even possible to drop the lock so we use atomic operations upon rb->bmap
and the variable migration_dirty_pages.  I didn't do it just to still be safe,
also not predictable whether the frequent atomic ops could bring overhead too
e.g. on huge vms when it happens very often.  When that really comes, we can
keep a local counter and periodically call atomic ops.  Keep it simple for now.

Peter XuandDr. David Alan Gilbert ca7bd0821b migration: Clear error at entry of migrate_fd_connect()
For each "migrate" command, remember to clear the s->error before going on.
For one reason, when there's a new error it'll be still remembered; see
migrate_set_error() who only sets the error if error==NULL.  Meanwhile if a
failed migration completes (e.g., postcopy recovered and finished), we
shouldn't dump an error when calling migrate_fd_cleanup() at last.
