If the domain is not running, but for example the CPUs are stopped, the
ACPI event gets queued and resume of the domain will just shut it off.

This bumps the release number of 2.0.0, to reflect the switch to
a new time based release versioning scheme. The downloads page
is updated to describe our policies for release schedules and
release version numbering

The stable release docs are changed to reflect the fact that
the stable version numbers are now just 3 digits long instead
of 4.

This option allows or disallows detection of zero-writes if it is set to
"on" or "off", respectively.  It can be also set to "unmap" in which
case it will try discarding that part of image based on the value of the

Building with clang 3.8 triggers the following error:

Fix by using 'const' for kvmhint declaration.

Populate libxl_domain_build_info struct with bios and firmware
info from virDomainLoaderDef.

Note: Currently libxl only allows specifying the type of BIOS.
For type LIBXL_BIOS_TYPE_OVMF, the firmware path is configured
when building Xen using '--with-system-ovmf='. If not specified,
LIBXL_FIRMWARE_DIR/ovmf.bin is used. In the future, Xen will
support a user-specified firmware path. See

http://lists.xenproject.org/archives/html/xen-devel/2016-03/msg01628.html

Once that work is merged into xen.git, the libvirt libxl driver
will be able to honor a user-specified path. In the meantime use
the implicit path, which is tolerable since it is advertised in
domcapabilities.

Add support to xenconfig for conversion of xl.cfg(5) bios config
to/from libvirt domXml <loader> config. SeaBIOS is the default
for HVM guests using upstream QEMU. ROMBIOS is the default when
using the old qemu-dm. This patch allows specifying OVMF as an
alternate firmware.

Example xl.cfg:
  bios = "ovmf"

Example domXML:
  <os>
    ...
    <loader readonly='yes' type='pflash'>/usr/lib/xen/boot/ovmf.bin</loader>
  </os>

Note that currently Xen does not support a separate nvram for
non-volatile variables.

The virQEMUDriverConfig object contains lists of
loader:nvram pairs to advertise firmwares supported by
by the driver, and qemu_conf.c contains code to populate
the lists, all of which is useful for other drivers too.

To avoid code duplication, introduce a virFirmware object
to encapsulate firmware details and switch the qemu driver
to use it.

In libxl driver we do virObjectRef in libxlDomainObjBeginJob,
If virCondWaitUntil failed, it goes to error, do virObjectUnref,
There's a chance that someone undefine the vm at the same time,
and refs unref to zero, vm is freed in libxlDomainObjBeginJob.
But the vm outside function is not Null, we do virObjectUnlock(vm).
That's how we overwrite the vm memory after it's freed. I fix it.

ARM/Aarch64 /proc/cpuinfo has no virtualization related flags.
Refactor the Qemu/KVM test a bit:

1) run the "for hardware virtualization" test only on plaforms with known
   cpuinfo flags (x86, s390)
2) test for /dev/kvm also on platforms where no cpu flags are set

Finally Add a more generic error hint message for non-x86 plaforms
when /dev/kvm is missing.

In 3704b900 ("tests: Add CPU detection tests"), a macro called
DO_TEST_CPUID_JSON is added. But it took only two arguments when QEMU
or YAJL is not set.

Fix it by adding a third argument. Shouldn't have any effect because
that macro compiles to nothing.

Currently, virt-login-shell is not allowed to build on Windows.
However, as it's designed around LXC, it does not make sense to
build it on anything but Linux, so make the check stricter and allow to
enable it on Linux only.

otherwise we drop variables like XDG_RUNTIME_DIR with qemu:///session
and libvirtd faild to find virtlogd's socket.

Don't use duplicating target dev names.

 * Fix misspelt function name:
    s/virHostCPUGetStatsFreebsd/virHostCPUGetStatsFreeBSD/
 * Mark the first argument to virHostCPUGetInfo with ATTRIBUTE_UNUSED
   as it's not actually used on non-Linux

SYSFS_SYSTEM_PATH is only defined for Linux, however it's used outside
of #ifdef __linux__ code, e.g. as the first argument to
nodeCapsInitNUMAFake().

But as this argument's value is used on Linux only, it's safe to define
SYSFS_SYSTEM_PATH to "fake" to get things built on FreeBSD.

As it turned out PrlVmDev_GetStackIndex can return negative values
without reporting an error, which is incorrect but nevertheless.
After that we feed this negative index to virIndexToDiskName,
which in turn returns NULL and we set it to virDomainDiskDef.dst.
Using virDiskNameToBusDeviceIndex with a virDomainDiskDef structure
which has NULL dst field crashes.
Fix this by returning an error in prlsdkGetDiskId in such cases.

The approach of subscribing on first stat API call and then waiting
for receiving of performance event from sdk to process the call originates
in times when every vz libvirt connections spawns its own sdk connection.
Thus without this waiting virsh stat call would return empty stats. Now
with single sdk connection this scheme is unnecessary complicated.

This patch subscribes to performance events on first domain appearence
and unsubscribe on its removing.

Unfortunately, our monitor code that handles talking to the qemu

BTW: it really is called "type" on the monitor, even though it's
called "name" on the cmd line. Don't ask.

Prior to joining the namespaces of the container, move the
process into the containers' cgroups, so that the shell that
is subsequently launched is under the container resource
constraints.

Currently the shell must be looked up from the config setting in
/etc/libvirt/virt-login-shell.conf. This is inflexible if there
are containers where different users need different shells. Add
add a new 'auto-shell' config parameter which instructs us to
query the containers' /etc/passwd for the shell to be exec'd.

The virt-login-shell environment will be initialized with
an arbitrary number of environment variables determined
by the SSH daemon and PAM configuration. Most of these are
not relevant inside the container, and at best they are
noise and at worst they'll break apps. For example if
XDG_RUNTIME_DIR is leaked to the container, it'll break
any apps using it, since  the directory it points to is
only visible to the host OS filesystem, not the container
FS.

Use clearenv() to blank out everything and then set known
good values for PATH, SHELL, USER, LOGNAME HOME and TERM.
Everything else is left up to the login shell to initialize.
