A few commits back I've introduced new 'virtio-pmem' <memory/>
device. Since it's virtio it goes onto PCI bus. Therefore, on
hotplug new PCI address is generated (or provided one is
reserved). However, if hotplug fails (for whatever reason) the
address needs to be released. This is different to 'dimm' type of
address because for that type we don't keep a map of used slots
rather generate one on each address assign request. The map is
then thrown away. But for PCI addresses we keep internal state
and thus has to keep it updated. Therefore, this new
qemuDomainReleaseMemoryDeviceSlot() function is NOP for those
models which use 'dimm' address type ('dimm' and 'nvdimm').
While I'm at it, let's release the address in case of hot unplug.
Not that is supported (any such attempt fails with the following
error:
"virtio based memory devices cannot be unplugged"
But if QEMU ever implements hot unplug then we don't have to
remember to fix our code.

Currently, nmdm console device requires user to specify master and slave
path attributes (such as /dev/nmdm0A and /dev/nmdm0B respectively).
However, making user find a non-occupied device name might be not
convenient, especially for the remote connections.
Update the logic to make these attributes optional. In case if not
specified, use /dev/nmdm$UUID[AB], where $UUID is a domain's UUID.
With this schema it's unlikely nmdm device will clash with other domains
or even other non-bhyve nmdm devices.

When deleting the vhostuserclient interface, OVS prompts that the interface does not exist,
Through the XML file, I found that the "target dev" has a '\n', results in an XML parsing error.
XML file:
<target dev='vm-20ac9c030a47

That is because 'ovs-vsctl' returns a newline result, always come with a '\n',
and the vircommandrun function puts it in ifname.
So virNetDevOpenvswitchGetVhostuserIfname should remove '\n' from ifname.

This function is only called from one place, and has, well... not a
*misleading* name, but it doesn't fit the standard frame of functions
that end in "Free" (it doesn't actually free the object pointed to by
its argument, but frees *some parts* of the content of the object).
Rather than try to think up an appropriate name, let's just move the
meat of this function into its one and only caller,
virNetLibsshSessionDispose(), which will allow us to convert its
VIR_FREEs into g_free in a future patch.

virDomainCapsDispose() was the only caller of
virDomainCapsStringValuesFree(), which 1) didn't actually free the
object it was called with, but only cleared it, making it less
mechanical to convert from VIR_FREE to g_free (since it's not
immediately obvious from looking at virDomainCapsStringValuesFree()
that the pointers being cleared will never again be used).
We could have renamed the function to virDomainCapsStringValuesClear()
to side-step the confusion of what the function actually does, but
that would just make the upcoming switch from VIR_FREE to g_free
require more thought. But since there is only a single caller to the
function, and it is a vir*Dispose() function (indicating that the
object containing the virDomainCapsStringValues is going to be freed
immediately after the function finishes), and thus VIR_FREE() *could*
be safely replaced by g_free()), we instead just move the contents of
virDomainCapsStringValuesFree() into virDomainCapsDispose() (and
*that* function will be trivially converted in an upcoming
"mechanical" patch).

This is another *Free() function that doesn't free the object it is
passed. Instead it frees and clears some parts of the object.
In this case, the function is actually called from two places, and one
of them (virNetSSHSessionAuthReset) appears to be assuming that the
pointers actually *will* be cleared. So the proper thing to do here
(?) is to rename the function to virNetSSHSesionAuthMethodsClear().
(NB: virNetSSHSessionAuthReset is seemingly never called from
anywhere. Is this one of those functions that actually *is* called by
some strange MACRO invocation? Or it is truly one of those
"written-but-never-used" functions that can be deleted? (if the latter
is the case, then I would rather move the contents of
virNetSessionAuthMethodsFree() into its only other caller,
virNetSSHSessionDispose(), so that the VIR_FREEs could be replaced
with g_free.)

These functions are all only called as a part of qemuFirmwareFree(),
which frees the qemuFirmware object before return, so we can be sure
none of the pointers is referenced after freeing (and thus there is no

These functions all cooperate to free memory pointed to by a single
object that contains (doesn't *point to*, but actually contains)
several sub-objects. They were written to send copies of these
sub-objects to subordinate functions, rather than just sending
pointers to the sub-objects.
Let's change these functions to just send pointers to the objects
they're cleaning out rather than all the wasteful and pointless
copying.

Several functions had the names virFirmware[something]Free(), but they
aren't taking a pointer to some object and freeing it. Instead, they
are making a copy of the content of an entire object, then Freeing the
objects pointed to by that content.
As a first step in a too-complicated cleanup just to eliminate a few
occurrences of VIR_FREE(), this patch renames those functions to more
accurately reflect what they do - they Free the *Content* of their
arguments.

dhcpHostFree() and addnHostFree() don't follow the normal pattern of
*Free functions in the rest of libvirt code - they are actually more
similar to the *Dispose() functions, in that they free all subordinate
objects, but not the object pointed to by the argument
itself. However, the arguments aren't virObjects, so it wouldn't be
proper to name them *Dispose() either.
They *currently* behave similar to a *Clear() function, in that they
free all the subordinate objects and nullify the pointers of those
objects. HOWEVER, we don't actually need or want that behavior - the
two functions in question are only called as part of a higher level
*Free() function, and the pointers are not referenced in any way
between the time they are freed and when the parent object is freed.
So, since the current name isn't correct, nor is *Dispose(), and we
want to change the behavior in such a way that *Clear() also wouldn't
be correct, lets name the functions *FreeContent(), which is an
accurate description of what the functions do, and what we *want* them
to do.
And since it's such a small patch, we can go ahead and change that
behavior - replacing the VIR_FREEs with g_free.
