vbox: Drop needless g_new0(..., 0) in vbox_snapshot_conf.c
clang on Fedora started to complain about some calls to g_new0()
we're making in vbox_snapshot_conf.c. Specifically, we're passing
zero as number of elements to allocate. And while usually SA
tools are not clever, in this specific case clang is right.
There are three cases where such call is made, but all of them
later use VIR_EXPAND_N() to allocate more memory (if needed). But
VIR_EXPAND_N() accepts a variable set to NULL happily.
Therefore, just drop those three calls to g_new0(..., 0) and let
VIR_EXPAND_N() allocate memory.

domain_interface: Introduce and use virDomainInterfaceClearQoS()
In QEMU and LXC drivers in a few places only
virNetDevBandwidthClear() is called. This means that if an
interface is of openvswitch vport profile, its QoS is not
removed. And to make matters worse - OVS is designed to remember
state even when corresponding interface is gone. This leads to
stale QoS settings piling up in OVS database.
To resolve this, introduce virDomainInterfaceClearQoS() which
looks at given interface and calls corresponding QoS clear
function. Then, basically replace virNetDevBandwidthClear() calls
in those hypervisor drivers with this new function.

Extend libvirt-guests to shutdown only persistent VMs
At the moment, there is no configuration option for the libvirt-guests
service that allows users to define that only persistent virtual machines
should be shutdown on host shutdown.
Currently, the service config allows to choose between two ON_SHUTDOWN
actions that are executed on running virtual machines when the host goes
down: shutdown, suspend.
The ON_SHUTDOWN action should be orthogonal to the type of the virtual
machine. However, the existing implementation, does not suspend
transient virtual machines.
This is the matrix of actions that is executed on virtual machines based
on the configured ON_SHUTDOWN action and the type of a virtual machine.
| persistent | transient
shutdown | shutdown | shutdown (what we want to change)
suspend | suspend | nothing
Add config option PERSISTENT_ONLY to libvirt-guests config that allows
users to define if the ON_SHUTDOWN action should be applied only on
persistent virtual machines. PERSISTENT_ONLY can be set to true, false,
default. The default option will implement the already existing logic.
Make sure the old value in `scsi_target->wwpn` is free'd before replacing it.
While at it, simplify the code.

While the virsh option definitions specify (either explicitly after

positional or not, the actual parser is way more lax and actually and

This creates situations such as 'snapshot-create-as' which has the

qemu_snapshot: correctly update metadata when deleting external snapshot with multiple branches
XML metadata for snapshot contains only single list of disk overlays
from the moment when the snapshot was taken. When user creates multiple
branches of snapshots the parent snapshot will still list only the
original disk overlays. This may cause an issue in a specific scenario:
s1
|
+- s2
+- s3 (active)
For this snapshot topology when we delete s2 metadata for s1 are not
updated. Now when we delete s1 the code operated with incorrect
overlays from s1 metadata in order to update s3 metadata resulting in no
changes to s3 metadata.
Now when user tries to delete s3 it fails with following error:
error: Failed to delete snapshot s3
error: operation failed: snapshot VM disk source and parent disk source are not the same
For the actual deletion there is a code to figure out the correct disk
source but it was not used to update metadata as well. Due to reasons
how block commit in libvirt works we need to create a copy of that disk
source in order to have it available when updating metadata as the
original source will be freed at that point.

qemu_snapshot: call qemuSnapshotDeleteUpdateDisks only for external snapshots
Calling this function when deleting internal snapshot isn't required
because with internal snapshots all changes are done within the file
itself so there is no file deletion and no need to update snapshot
metadata.

pci: Remove error reporting from PCI VPD parsing
The PCI VPD (Vital Product Data) may be missing or the kernel can report
presence but not actually have the data. Also the data is specified by
the device vendor and thus may be invalid in some cases.
To avoid log spamming, since the only usage in the node device driver is
ignoring errors, remove all error reporting.

virpcivpd: Revert error reporting from PCI VPD parser
The VPD parsing is fragile and depends on hardware vendor's adherance to
standards. Since libvirt only ever uses this data to report it in the
nodedev XML which ignores any errors there's no much point in having
error reporting which I've added recently.
Turn the errors into VIR_DEBUG statements in preparation for upcoming
patch which completely removes the expectation to report errors.
