The sysinfo code used by QEMU is trivially portable to the
LXC driver

The nodedev driver currently only detects harddisk, cdrom
and floppy devices. This adds support for SD cards, which
are common storage for ARM devices, eg the Google ChromeBook

<device>
  <name>block_mmcblk0_0xb1c7c08b</name>
  <parent>computer</parent>
  <capability type='storage'>
    <block>/dev/mmcblk0</block>

    <serial>0xb1c7c08b</serial>
    <size>15758000128</size>
    <logical_block_size>512</logical_block_size>
    <num_blocks>30777344</num_blocks>

Now that we force all containers to have a root filesystem,
there is no way the host's /dev is ever exposed
Signed-off-by: NDaniel P. Berrange <berrange@redhat.com>

Currently the LXC container code has two codepaths, depending on
whether there is a <filesystem> element with a target path of '/'.
If we automatically add a <filesystem> device with src=/ and dst=/,
for any container which has not specified a root filesystem, then
we only need one codepath for setting up the filesystem.

Early on kernel support for private devpts was not widespread,
so we had compatibiltiy codepaths. Such old kernels are not
seriously used for LXC these days, so the compat code can go
away

When creating a logical volume with virStorageVolCreateXMLFrom,
"qemu-img convert" is called internally if clonevol is a file volume.
Then, vol->target.format is used as output_fmt parameter but the
target.format of logical volumes is always 0 because logical volumes
haven't the volume format type element.

Fortunately, 0 was treated as RAW file format before commit f772b3d9,
so there was no problem. But now, 0 is treated as the type of none,
qemu-img fails with "Unknown file format 'none'".

This patch fixes this issue by treating output block devices as RAW
file format like for input block devices.

Introduced by 8d68cbea

Commit f84b92ea introduced a memory leak on error; John Ferlan reported
that valgrind caught it during 'make check'.

* src/qemu/qemu_command.c (qemuBuildMachineArgStr): Plug leak.

By passing the flags -z relro -z now to the linker, we can force
it to resolve all library symbols at startup, instead of on-demand.
This allows it to then make the global offset table (GOT) read-only,
which makes some security attacks harder.

PIE (position independent executable) adds security to executables
by composing them entirely of position-independent code (PIC. The
.so libraries already build with -fPIC. This adds -fPIE which is
the equivalent to -fPIC, but for executables. This for allows Exec
Shield to use address space layout randomization to prevent attackers
from knowing where existing executable code is during a security
attack using exploits that rely on knowing the offset of the
executable code in the binary, such as return-to-libc attacks.

The JSON generator is able to represent only values less than LLONG_MAX, fix the
bandwidth limit checks when converting to value to catch overflows before they
reach the generator.

It's long enough to have a independant definition.

Every source file is currently built twice by libtool, once for
the shared library and once for the static library. Static libs
are not commonly packaged by distros and slow down compilation
time by more than 50% compared to a shared-only build time.

Time for 'make -j 4':

      shared only: 2 mins  9 secs
  shared + static: 3 mins 26 secs

Time for non-parallel make

      shared only: 3 mins 32 secs
  shared + static: 5 mins 41 secs

Those few people who really want them, can pass --enable-static
to configure

Disabling them by default requires use of LT_INIT, but for
compat with RHEL5 we can't rely on that. So we conditionally
use LT_INIT, but fallback to AM_PROG_LIBTOOL if not present.

If a user configures a domain to use a seclabel of a specific type,
but the appropriate driver is not accessible, we should refuse to
start the domain. For instance, if user requires selinux, but it is
either non present in the system, or is just disabled, we should not
start the domain. Moreover, since we are touching only those labels we
have a security driver for, the other labels may confuse libvirt when
reconnecting to a domain on libvirtd restart. In our selinux example,
when starting up a domain, missing security label is okay, as we
auto-generate one. But later, when libvirt is re-connecting to a live
qemu instance, we parse a state XML, where security label is required
and it is an error if missing:

  error : virSecurityLabelDefParseXML:3228 : XML error: security label
  is missing

This results in a qemu process left behind without any libvirt control.

virsh schedinfo was able to set only one parameter at a time (not
counting the deprecated options), but it is useful to set more at
once, so this patch adds the possibility to do stuff like this:

virsh schedinfo <domain> cpu_shares=0 vcpu_period=0 vcpu_quota=0 \
emulator_period=0 emulator_quota=0

Invalid scheduler options are reported as well.  These were previously
reported only if the command hadn't updated any values (when
cmdSchedInfoUpdate returned 0).

The virsh(1) man page wasn't saying anything about the 'migrateuri'
parameter other than it can be usually omitted.  A patched version of
docs/migrate.html.in is taken in this patch to fix that up in the man
page.

Use the established approach to improve this function too.

Use the established approach to improve this function too.

Use the established approach to improve this function too.

The man page states that with --config the next boot is affected. This
can be understood as if _only_ the next boot was affected. This isn't
true if the machine is running.

This patch adds the full --live, --config, --current infrastructure and
tweaks stuff to correctly support the obsolete --persistent flag.

Note that this patch changes the the behavior of the --config flag to match the
use of this flag in rest of libvirt. This flag was mistakenly renamed from
--persistent that originaly had different semantics.

The parameter options can be declared directly.

Also use macros for mutual exclusion on some of the incompatible
parameter variables.

This patch uses the new helper to avoid the more complex check for
domain state modification flags.

The domif-getlink command did not terminate successfully when the
interface state was found. As the code used old and too complex approach
to do the job, this patch refactors it and fixes the bug.

Format the address using the helper instead of having similar code in
multiple places.

This patch also fixes leak of the MAC address string in
ebtablesRemoveForwardAllowIn() and ebtablesAddForwardAllowIn() in
src/util/virebtables.c

The domain XML generator creates the mac addres strings with lowercase
strings with a separate piece of code. This patch changes the formating
helper to do the same stuff to allow using it to normalize a string
provided by the user. After this change some of the tests that are
outputing the mac address will need to be changed.

Currently, -machine option is used only when dump-guest-core is set.

To use options defined in machine option for newer version of QEMU,
it needs to use -machine xxx, and to be compatible with older version
-M, this patch adds QEMU_CAPS_MACHINE_OPT capability for newer
version which supports -machine option.

The limits are documented at

when going through XML parsing in addition to being enforced by the API.

This is just a bare Easter Egg. Whenever a user runs virDomainScreenshot
over a domain in test driver, he'll get the Libvirt PNG logo in return.

Present since introduction of smartcard support in commit f5fd9baa

* src/qemu/qemu_command.c (qemuBuildCommandLine): Match qemu spelling.
* tests/qemuxml2argvdata/qemuxml2argv-smartcard-host-certificates.args:
Fix broken test.

Allow migration over IPv6 by listening on [::] instead of 0.0.0.0
when QEMU supports it (QEMU_CAPS_IPV6_MIGRATION) and there is
at least one v6 address configured on the system.

Use virURIParse in qemuMigrationPrepareDirect to allow parsing
IPv6 addresses, which would cause an 'incorrect :port' error
message before.

Move setting of migrateFrom from qemuMigrationPrepare{Direct,Tunnel}
after domain XML parsing, since we need the QEMU binary path from it
to get its capabilities.

The 'virsh vcpupin' and 'virsh emulatorpin' commands use the same
code to parse the cpulist. This patch abstracts the same code as
a helper. Along with various code style fixes, and error improvement
(only error "Physical CPU %d doesn't exist" if the specified CPU
exceed the range, no "cpulist: Invalid format", see the following
for an example of the error prior to this patch).

% virsh vcpupin 4 0 0-8
error: Physical CPU 4 doesn't exist.
