An upcoming patch will be checking if the addition of a new net device
requires adjusting the domain locked memory limit, which must be done
prior to sending the command to qemu to add the new device. But
qemuDomainAdjustMaxMemLock() checks all (and only) the devices that
are currently in the domain definition, and currently we are adding
new net devices to the domain definition only at the very end of the
hotplug operation, after qemu has already executed the device_add
command.
In order for the upcoming patch to work, this patch changes
qemuDomainAttachNetDevice() to add the device to the domain nets list
at an earlier time. It can't be added until after PCI address and
alias name have been determined (because both of those examine
existing devices in the domain to figure out a unique value for the
new device), but must be done before making the qemu monitor call.
Since the device has been added to the list earlier, we need to
potentially remove it on failure. This is done by replacing the
existing call to virDomainNetRemoveHostdev() (which checks if this is
a hostdev net device, and if so removes it from the hostdevs list,
since it could have already been added to that list) with a call to
the new virDomainNetRemoveByObj(), which looks for the device on both
nets and hostdevs lists, and removes it where it finds it.

virDomainNetRemove() requires the index of the net device you want to
remove from the list, but in some cases you may not have the index
handy, only the object itself (or the object may not have been added
to the domain's list). virDomainNetRemoveByObj() first tries to find
the given object in the nets list, and deletes that if it is found.
As with virDomainNetRemove() it always unconditionally tries to remove
the device from the hostdevs list (in case it is the ridiculous
combined net+hostdev device created for <interface type='hostdev'>).

We have many places where the earliest error returns from a function
skip any cleanup label at the bottom (the assumption being that it is
so early in the function that there isn't yet anything that needs to
be explicitly undone on failure). But in general it is a bad sign if
there are any direct "return" statements in a function at any time
after there has been a "goto cleanup" - that indicates someone thought
that an earlier point in the code had done something needing cleanup,
so we shouldn't be skipping it.
There were two occurences of a "return -1" after "goto cleanup" in
qemuDomainAttachDeviceNet(). The first of these has been around for a
very long time (since 2013) and my assumption is that the earlier
"goto cleanup" didn't exist at that time (so it was proper), and when
the code further up in the function was added, the this return -1 was
missed. The second was added during a mass change to check the return
from qemuInterfacePrepareSlirp() in several places (commit
99a1cfc438); in this case it was erroneous from the start.
Change both of these "return -1"s to "goto cleanup". Since we already
have code paths earlier in the function that goto cleanup, this should
not cause any new problem.

There was a recent change in libxml2 that caused a trouble for
us. To us, <metadata/> in domain or network XMLs are just opaque
value where management application can store whatever data it
finds fit. At XML parser/formatter level, we just make a copy of
the element during parsing and then format it back. For
formatting we use xmlNodeDump() which allows caller to specify
level of indentation. Previously, the indentation was not
applied onto the very first line, but as of v2.9.12-2-g85b1792e
libxml2 is applying indentation also on the first line.
This does not work well with out virBuffer because as soon as we
call virBufferAsprintf() to append <metadata/> element,
virBufferAsprintf() will apply another level of indentation.
Instead of version checking, let's skip any indentation added by
libxml2 before virBufferAsprintf() is called.
Note, the problem is only when telling xmlNodeDump() to use
indentation, i.e. level argument is not zero. Therefore,
virXMLNodeToString() which also calls xmlNodeDump() is safe as it
passes zero.

supporting hotplug and the hotplug code while starting up the VM.
When we have such disk we need to issue a system-reset so that firmware
