This enables support for running QEMU embedded to the calling
application process using a URI:
qemu:///embed?root=/some/path
Note that it is important to keep the path reasonably short to
avoid risk of hitting the limit on UNIX socket path names
which is 108 characters.
When using the embedded mode with a root=/var/tmp/embed, the
driver will use the following paths:
logDir: /var/tmp/embed/log/qemu
swtpmLogDir: /var/tmp/embed/log/swtpm
configBaseDir: /var/tmp/embed/etc/qemu
stateDir: /var/tmp/embed/run/qemu
swtpmStateDir: /var/tmp/embed/run/swtpm
cacheDir: /var/tmp/embed/cache/qemu
libDir: /var/tmp/embed/lib/qemu
swtpmStorageDir: /var/tmp/embed/lib/swtpm
defaultTLSx509certdir: /var/tmp/embed/etc/pki/qemu
These are identical whether the embedded driver is privileged
or unprivileged.
This compares with the system instance which uses
logDir: /var/log/libvirt/qemu
swtpmLogDir: /var/log/swtpm/libvirt/qemu
configBaseDir: /etc/libvirt/qemu
stateDir: /run/libvirt/qemu
swtpmStateDir: /run/libvirt/qemu/swtpm
cacheDir: /var/cache/libvirt/qemu
libDir: /var/lib/libvirt/qemu
swtpmStorageDir: /var/lib/libvirt/swtpm
defaultTLSx509certdir: /etc/pki/qemu
At this time all features present in the QEMU driver are available when
running in embedded mode, availability matching whether the embedded
driver is privileged or unprivileged.

The "ps2" bus is only available on certain machines like x86. On

Looking at the QEMU sources, PS/2 is only available if the QEMU binary

devices if this QEMU device is available, or if we're on x86 anyway

Libvirt's original atomic ops impls were largely copied
from GLib's code at the time. The only API difference
was that libvirt's virAtomicIntInc() would return a
value, but g_atomic_int_inc was void. We thus use
g_atomic_int_add(v, 1) instead, though this means
virAtomicIntInc() now returns the original value,
instead of the new value.
This rewrites libvirt's impl in terms of g_atomic_int*
as a short term conversion. The key motivation was to
quickly eliminate use of GNULIB's verify_expr() macro
which is not a direct match for G_STATIC_ASSERT_EXPR.
Long term all the callers should be updated to use
g_atomic_int* directly.

In order to avoid holding an agent job and a normal job at the same
time, we want to avoid accessing the domain's definition while holding
the agent job. To achieve this, qemuAgentGetFSInfo() only returns the
raw information from the agent query to the caller. The caller can then
release the agent job and then proceed to look up the disk alias from
the vm definition. This necessitates moving a few helper functions to
qemu_driver.c and exposing the agent data structure (qemuAgentFSInfo) in
the header.
In addition, because the agent function no longer returns the looked-up
disk alias, we can't test the alias within qemuagenttest. Instead we
simply test that we parse and return the raw agent data correctly.

Update the host CPU code to report the die_id in the NUMA topology
capabilities. On systems with multiple dies, this fixes the bug
where CPU cores can't be distinguished:
<cpus num='12'>
<cpu id='0' socket_id='0' core_id='0' siblings='0'/>
<cpu id='1' socket_id='0' core_id='1' siblings='1'/>
<cpu id='2' socket_id='0' core_id='0' siblings='2'/>
<cpu id='3' socket_id='0' core_id='1' siblings='3'/>
</cpus>
Notice how core_id is repeated within the scope of the same socket_id.
It now reports
<cpus num='12'>
<cpu id='0' socket_id='0' die_id='0' core_id='0' siblings='0'/>
<cpu id='1' socket_id='0' die_id='0' core_id='1' siblings='1'/>
<cpu id='2' socket_id='0' die_id='1' core_id='0' siblings='2'/>
<cpu id='3' socket_id='0' die_id='1' core_id='1' siblings='3'/>

This patch introduces a new PCI hostdev address type called
'unassigned'. This new type gives users the option to add
PCI hostdevs to the domain XML in an 'unassigned' state, meaning
that the device exists in the domain, is managed by Libvirt
like any regular PCI hostdev, but the guest does not have
access to it.
This adds extra options for managing PCI device binding
inside Libvirt, for example, making all the managed PCI hostdevs
declared in the domain XML to be detached from the host and bind
to the chosen driver and, at the same time, allowing just a
subset of these devices to be usable by the guest.
Next patch will use this new address type in the QEMU driver to
avoid adding unassigned devices to the QEMU launch command line.
