The storage pool code now attempts to disable COW by default on btrfs,
but management applications may wish to override this behaviour. Thus we
introduce a concept of storage pool features:
<features>
<cow state='yes|no'/>
</features>
If the <cow> feature policy is set, it will be enforced. It will always
return an hard error if COW cannot be explicitly set or unset.

This calls virFileSetCOW when building a pool with a request to attempt,
but not require, COW to be disabled. The effect is that nothing changes
on non-btrfs filesystems, but btrfs will get COW disabled on the
directory. This setting is then inherited by all newly created files in
the pool, avoiding the need for mgmt app to set "nocow" on a per-volume
basis.

When disabling COW on individual files, we now use the virFileSetCOW
method. Note that this change has a slight semantic difference to the
old implementation.
The original code reported errors but returned success when disabling
COW failed.
With this new code, we will always report an error if the user requested
disabling of COW and we could not honour it, either because btrfs
returned an error, or because the filesystem is not btrfs.

btrfs defaults to performing copy-on-write for files. This is often
undesirable for VM images, so we need to be able to control whether this
behaviour is used.
The virFileSetCOW() will allow for this. We use a tristate, since out of
the box, we want the default behaviour attempt to disable cow, but only
on btrfs, silently do nothing on non-btrfs. If someone explicitly asks
to disable/enable cow, then we want to raise a hard error on non-btrfs.

token:
#define
VIR_USE_CPU(cpumap,cpu)
((cpumap)[(cpu)

|=

which is more convenient to process later on in the script.

With the move to GitLab CI one of the things we miss from Jenkins is a
single page dashboard showing CI status across all projects. This is a
very simple replacement that uses badges for CI pipeline status.
A CSS tweak is needed because RST->HTML adds redundant <p> tags inside
table cells which causes excessive vertical whitespace to appear.

To attempt to catch unit tests which accidentally create files in $HOME,
or $XDG_RUNTIME_DIR, poison these env vars by pointing them to
directories which don't exist. This should give easier to debug test
failures. For example:
$ VIR_TEST_DEBUG=1 ./qemuhotplugtest
Could not initialize HostdevManager - operation failed: Failed to create state dir '/bad-test-used-env-xdg-runtime-dir/libvirt/hostdevmgr'

The virConnectGetType() returns "Xen" for libxl, not "LIBXL".
This prevents users opening a connection to the libxl driver when using

In the past we added 1024 bytes of padding to saved state images so that
users can run "virsh managedsave-edit $GUEST" and make XML changes which
increase the size of the XML document. This padding was accidentally
lost a while back

qemu: Remove unnecessary calculations in qemuDomainSaveMemory
The original 1024 bytes was unreasonably stingy when we consider that
the QEMU state is typically going to be many 100's of MB in size. Thus
this adds 64 KB of padding after the XML which should cope with any
plausible modifications a user will want to make.

Travis includes gnutls in the default package set, but it is
an outdated version linkng to an incompatible libffi version.
The 'update: true' stanza causes the brew toolchain to be
updated but not the installed formula. It is possible to
run 'brew upgrade' to update installed formula, but this is
very slow adding more than 5 minutes to the build time.
Listing the gnutls package explicitly causes it to be updated
without extending the build time.

Changes in the API:
- APIs related to the graphics adapter are no longer on the
IMachine interface, but on a IGraphicsAdapter interface
- The LaunchVMProcess method takes a list of env variables
instead of a single variable containing a concatenated
list. Since we only ever pass a single env variable, we
can simply stuff it straight into a list.
- The DHCP server start method no longer needs the network
name

Long ago we switched the vbox driver to run inside libvirtd to avoid
libvirt.so being polluted with GPLv2-only code. Since libvirtd is not
built on Windows, we disabled vbox on Windows builds. Thus the MSCOM
glue code is not required.

We previously added a hack to symlink CSS files from the source dir into

have also done this for any images.
This change merges several variables into one "$(assets)" so that we
