Up until now the traffic control filters for the vNIC QoS were
matching only ip traffic. For egress traffic that was unnoticed
because the unmatched traffic would just go to the default htb class
and be shaped anyway. For ingress, though, since the policing of the
rate is done by the filter itself.
The problem is solved by changing protocol to all and making anything
match the filter.

nmdm is a FreeBSD driver which allows to create a pair of tty
devices one of which is passed to the guest and second is used
by the client.
This patch adds new 'nmdm' character device type. Its definition
looks this way:
<serial type='nmdm'>
<source master='/dev/nmdm0A' slave='/dev/nmdm0B'/>
</serial>
Master is passed to the hypervisior and slave is used for client
connection.
Also implement domainOpenConsole() for bhyve driver based on that.
Right now, virStorageFileMetadata tracks bool backingStoreIsFile
for whether the backing string specified in metadata can be
resolved as a file (covering both block and regular file
resources) or is treated as a network protocol. But when
merging this struct with virStorageSource, it will be easier
to just actually track which type of resource it is, as well
as have a reserved value for the case where the resource type
is unknown (or had an error during probing).

I'm about to add fields to virStorageFileMetadata, which means
also adding fields to the testFileData struct in virstoragetest.
Alas, adding even one pointer on an x86_64 machine gave me a
dreaded compiler error:
virstoragetest.c:712:1: error: the frame size of 4208 bytes is larger than 4096 bytes [-Werror=frame-larger-than=]
After some experimentation, I realized that each test was creating
yet another testChainData (which contains testFileData) on the stack;
forcing the reuse of one of these structures instead of creating a
fresh one each time drastically reduces the size requirements. While
at it, I also got rid of a lot of intermediate structs, with some
macro magic that lets me directly build up the destination chains
inline.
For a bit more insight into what this patch does:
The old code uses an intermediate variable as a fixed-size array
of structs:
testFileData chain[] = { a, b };
data.files = chain;
In the new code, the use of VIR_FLATTEN_* allows the TEST_CHAIN()
macro to still take a single argument for each chain, but now of
the form '(a, b)', where it is turned into the var-args 'a, b'
multiple arguments understood by TEST_ONE_CHAIN(). Thus, the
new code avoids an intermediate variable, and directly provides
the list of pointers to be assigned into array elements:
data.files = { &a, &b };
* tests/virstoragetest.c (mymain): Rewrite TEST_ONE_CHAIN to
reuse the same struct for each test, and to take the data
inline rather than via intermediate variables.
(testChainData): Use bounded array of pointers instead of
unlimited array of struct.
(testStorageChain): Reflect struct change.

Commit id '18642d10' refactored the call to virCommandRunRegex()
inside a new function virStorageBackendFileSystemNetFindNFSPoolSources(),
but the cut-n-paste didn't remove the "&state". Now that state is passed
by reference, it results in a libvirtd core with a messages entry:
"...internal error: unknown storage pool type Unknow"
For example, the file /proc/cpuinfo for 24 cores PowerPC platform is larger than
the previous maximum size 2KB.
It will fail to start libvirtd with the error message as below:
virFileReadAll: Failed to read file '/proc/cpuinfo': Value too large for defined

There is a domain id in the virDomain structure as well as in the
virDomainObj structure. While the former can become stale the latter
is kept up to date. So it is safer to always (virDomainObjPtr)->def->id
internally.
This will fix issues seen when managing Xen guests through libvirt from
virt-manager (not being able to get domain info after define or reboot).
This was caused both though libxlDomainGetInfo() only but there were
a lot of places that might potentially cause issues, too.

Commit 5b3492fa aimed to fix this and caught one error but exposed
another one. When agent command is being executed and the thread
waiting for the reply is woken up by an event (e.g. EOF in case of
shutdown), the command finishes with no data (rxObject == NULL), but
no error is reported, since this might be desired by the caller
(e.g. suspend through agent). However, in other situations, when the
data are required (e.g. getting vCPUs), we proceed to getting desired
data out of the reply, but none of the virJSON*() functions works well
with NULLs. I chose the way of a new parameter for qemuAgentCommand()
function that specifies whether reply is required and behaves
according to that.

When looking up a net device by a MAC and PCI address, it is possible
that we've got a match on the MAC address but failed to match the
PCI address.
In that case, outputting just the MAC address can be confusing.
Partially resolves:
https://bugzilla.redhat.com/show_bug.cgi?id=872028
Every caller checked the return value and logged an error
- one if no device with the specified MAC was found,
other if there were multiple devices matching the MAC address
(except for qemuDomainUpdateDeviceConfig which logged the same
message in both cases).
Move the error reporting into virDomainNetFindIdx, since in both cases,
we couldn't find one single match - it's just the error messages that
differ.
No need to spawn a child 'rm' process when we can do it ourselves.

Currently VolOpen notifies the user of a potentially non-fatal failure by
returning -2 and logging a VIR_WARN or VIR_INFO. Unfortunately most
callers treat -2 as fatal but don't actually report any message with
the error APIs.
Rename the VOL_OPEN_ERROR flag to VOL_OPEN_NOERROR. If NOERROR is specified,
we preserve the current behavior of returning -2 (there's only one caller
that wants this).
However in the default case, only return -1, and actually use the error
APIs. Fix up a couple callers as a result.
Coverity complains about a possible leak of seclabel if

One of the features of qcow2 is that a wrapper file can have
more capacity than its backing file from the guest's perspective;
what's more, sparse files make tracking allocation of both

Some preparatory work before consolidating storage volume
structs with the rest of virstoragefile. Making these
changes allows a volume target to be much closer to (a
subset of) the virStorageSource struct.
Making perms be a pointer allows it to be optional if we
have a storage pool that doesn't expose permissions in a
way we can access. It also allows future patches to
optionally expose permissions details learned about a disk
image via domain <disk> listings, rather than just
limiting it to storage volume listings.
Disk partition types was only used by internal code to
control what type of partition to create when carving up
an MS-DOS partition table storage pool (and is not used
for GPT partition tables or other storage pools). It was
not exposed in volume XML, and as it is more closely
related to extent information of the overall block device
than it is to the <target> information describing the host
file. Besides, if we ever decide to expose it in XML down
the road, we can move it back as needed.

On all the places where qemuAgentComand() was called, we did a check

have resulted in a crash.
So this patch makes the error-checking part of qemuAgentCommand()

b) makes the check mandatory and, most importantly,
c) checks for the errors if and only if it is appropriate.
This actually fixes a potential crashers when qemuAgentComand()

In 'make syntax-check', we have a rule that prevents layering
violations between the various files in src. However, we
forgot to treat conf/ and the more recently-added access/ as
lower-level directories, and were not detecting cases where
they might have used a driver file. Also, it's not nice that
qemu can use storage/ but none of the other drivers could do so.
* cfg.mk (sc_prohibit_cross_inclusion): Tighten rules for conf/
and access/, let all other drivers use storage/.

Use the "gluster" command line tool to retrieve information about remote
volumes on a gluster server to allow storage pool source lookup.
Unfortunately gluster doesn't provide a management library so that we
could use that directly, instead the RPC calls are hardcoded in the
command line tool.
Extract the NFS related stuff into a separate function and tidy up the
rest of the code so we can reuse it to add gluster backend detection.
Additionally avoid reporting of errors from "showmount" and return an
empty source list instead. This will help when adding other detection
backends.
