c7ccd8b2e6 virsh: Create macro for common "persistent" option
Rather than continually cut-n-paste the strings into each command,
create a common macro to be used generically.  Note that not all
'{.name = "persistent",' entries are replaced, just those that have the
common .help string of "make live change persistent".

Non replaced instances are unique to the command.

b6fb1e245c virsh: Create macro for common "domain" option
Rather than continually cut-n-paste the strings into each command,
create a common macro to be used generically. The macro will take a
single argument _helpstr which will be used to pass the translatable
helpstr since not all domain options can take the same string.

The majority of the options take 'N_("domain name, id or uuid")', so
create a separate macro with a _FULL suffix while those that do not
take the same string will use the VIRSH_COMMON_OPT_DOMAIN macro.

70c6e67766 virsh: Adjustments for the VIRSH_COMMON_OPT_POOL
The macro is slightly adjusted to add an argument "_helpstr". This
will be passed as a translation macro string since other uses of the
option may not have the same exact help string (such as is the case
when the uuid is not suppliable for create commands).

In virsh-pool.c - we'll create a singular VIRSH_COMMON_OPT_POOL_FULL
in order to pass along the 'N_("pool name or uuid")'

In virsh-volume.c there will be a VIRSH_COMMON_OPT_POOL_FULL and a
VIRSH_COMMON_OPT_POOL_NAME, which passes 'N_("pool name")' for
the commands that can only pass a name. There will also be a
VIRSH_COMMON_OPT_POOL_OPTIONAL which is used for the command
options which use OT_STRING and don't require the --pool argument.

f688b808ad virsh: Convert VSH_POOL_ macro to VIRSH_COMMON_OPT_
Commit id's 'cf793b00', 'e178688f', 'f9a6110f', '5372d49', and 'e193735'
added new VSH_POOL_ macros; however, it was pointed out after push that
commit id '834c5720' preferred use of VIRSH_ for the prefix over VSH_.

So this patch just changes the VSH_ to VIRSH_ and it changes the naming
format from VIRSH_<opt>_OPT_COMMON to VIRSH_COMMON_OPT_<opt>.

21e63916dc util: eliminate bogus error log in virNetDevVPortProfileGetStatus
if instanceId is NULL

When virNetDevVPortProfileGetStatus() was called with instanceId =
NULL (which is the case for all DISASSOCIATE requests in 802.1Qbh) it
would log the following error:

   Could not find netlink response with expected parameters

even though the disassociate had been successfully completely. Then,
due to the fortunate coincidence of status having been initialized to
0 and then not changed when the "failure" was encountered, it would
still return a status of 0 (PORT_VDP_RESPONSE_SUCCESS), so the caller
would assume a successful operation.

This would result in a spurious log message though, and would fill in
LastErrorMessage, so that the API would return that error if it
happened during cleanup from some other error. That, in turn, would
lead to an incorrect supposition that the response to the port profile
disassociate was the cause of the failure.

During debugging, I noticed that the VF in question usually had *no
uuid* associated with it (big surprise)by the time the disassociate
completed, so the solution is *not* to send the previous instanceId
down.

This patch fixes virNetDevVPortProfileGetStatus() to only check the
VF's uuid in the status if it was given an instanceId to check against
when originally called. Otherwise it only checks that the particular
VF is present (it will be).

This does cause a slight difference in behavior - rather than
returning with status unchanged (and thus always 0) it will actually
get the IFLA_PORT_RESPONSE. This could lead to revelation of error
conditions we were previously ignoring. Or not. So far "not".

bd04ad42e7 qemu: auto-add a USB2 controller set for Q35 machines
Use virDomainDefAddUSBController() to add an EHCI1+UHCI1+UHCI2+UHCI3
controller set to newly defined Q35 domains that don't have any USB
controllers defined.

8ebca27bb7 qemu: define virDomainDevAddUSBController()
This new function will add a single controller of the given model,
except the case of ich9-usb-ehci1 (the master controller for a USB2
controller set) in which case a set of related controllers will be
added (EHCI1, UHCI1, UHCI2, UHCI3). These controllers will not be
given PCI addresses, but should be otherwise ready to use.

"-1" is allowed for controller model, and means "default for this
machinetype". This matches the existing practice in
qemuDomainDefPostParse(), which always adds the default controller
with model = -1, and relies on the commandline builder to set a model
(that is wrong, but will be fixed later).

ed64d92bea conf: add virDomainDefAddController()
We need a virDomainDefAddController() that doesn't check for an
existing controller at the same index (since USB2 controllers must be
added in sets of 4 that are all at the same index), so rather than
duplicating the code in virDomainDefMaybeAddController(), split it
into two functions, in the process eliminating existing duplicated
code that loops through the controller list by calling
virDomainControllerFind(), which does the same thing).

163338ec28 qemu: prefer 00:1D.x and 00:1A.x for USB2 controllers on Q35
The real Q35 machine puts the first USB controller set (EHCI+(UHCIx4))
on bus 0 slot 0x1D, and the 2nd USB controller set on bus 0 slot 0x1A,
so let's attempt to make the virtual machine match that for
controllers with auto-assigned addresses when possible.

Three test cases were added to assure that the proper addresses are
assigned - one with a single set of unaddressed USB controllers, one
with 3 (to grab both preferred slots plus one more), and one with the
order of the controller definitions reordered, to assure that the
auto-assignment isn't mixed up by order.

7dbb5fce06 qemu: don't assume slot 0 is unused/reserved.
When qemuAssignDevicePCISlots() is looking for companion controllers
for a USB controller that has no PCI address specified, it initializes
a virDevicePCIAddress to 0000:00:00.0, fills it in with the
companion's address if one is found, then checks whether or not there
was a find based on slot == 0. On a system with a single PCI bus, that
is a valid way to check, because slot 0 is reserved, but on most other
PCI buses, slot 0 is not reserved, and is open for use by any
device. This patch adds a separate bool that is set when a companion
is found rather than relying on the faulty information provided with
"slot == 0".

da176bf6b7 examples: Use one top level makefile
Using one Makefile per example subdirectory essentially serializes 'make'
calls. Convert to one example/Makefile that builds and distributes
all the subdir files. This reduces example/ rebuild time from about 5.8
seconds to 1.5 seconds on my machine.

One slight difference is that we no longer ship Makefile.am with the
examples in the rpm. This was virtually useless anyways since the Makefile
was very specific to libvirt infrastructure, so wasn't generically
reusable anyways.

that is the legacy default.  The condition is so big that it was just a

libvirt expresses outgoing limits by average (required), peak, burst,

bandwidth limit by converting the average KB/s to bytes per interval
based on the same default interval (50ms) used by xl.
