If the pool creation thread happens to detect the luns in
the scsi target, the size parameters will be calculated as
part of the refreshPool called from storagePoolCreate().
This means the virStoragePoolFCRefreshThread (commit id
'512b874') waiting to run and "refresh" the pool will
essentially double the allocation and capacity values.
A separate refresh would correct the values.
To avoid this, the FCRefreshThread needs to reinitialize
the pool size values prior to calling virStorageBackendSCSIFindLUs
which eventually calls virStorageBackendSCSINewLun and
updates the size values for each volume found.
After the recent commits the build didn't work for me. Fix it by
using size_t as the callback argument is using and the correct
formatter. The attempted fixup to use %llu as a formatter was wrong.
Commit e6336442 changed the 'out:' label to 'cleanup' in

This patch adds support for "vpindex", "runtime", "synic",
"stimer", and "vendor_id" features available in qemu 2.5+.
- When Hyper-V "vpindex" is on, guest can use MSR HV_X64_MSR_VP_INDEX
to get virtual processor ID.
- Hyper-V "runtime" enlightement feature allows to use MSR
HV_X64_MSR_VP_RUNTIME to get the time the virtual processor consumes
running guest code, as well as the time the hypervisor spends running
code on behalf of that guest.
- Hyper-V "synic" stands for Synthetic Interrupt Controller, which is
lapic extension controlled via MSRs.
- Hyper-V "stimer" switches on Hyper-V SynIC timers MSR's support.
Guest can setup and use fired by host events (SynIC interrupt and
appropriate timer expiration message) as guest clock events
- Hyper-V "reset" allows guest to reset VM.
- Hyper-V "vendor_id" exposes hypervisor vendor id to guest.

After the patches that added tracking of in-use macvtap names (commit
370608, first appearing in libvirt-1.3.2), if the function to allocate
a new macvtap device came to a device name created outside libvirt, it
would retry the same device name MACVLAN_MAX_ID (8191) times before
finally giving up in failure.
The problem was that virBitmapNextClearBit was always being called
with "0" rather than the value most recently checked (which would
increment each time through the loop), so it would always return the
same id (since we dutifully release that id after failing to create a
new device using it).

networkStartNetwork() and networkShutdownNetwork() were calling the
wrong type-specific function in the case of networks that were
configured for macvtap ("direct") bridge mode - they were instead
calling the functions for a tap+bridge network. Currently none of
these functions does anything (they just return 0) so it hasn't
created any problems, but that could change in the future.
Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1316465
An attempt to simplify the code for the VIR_NETWORK_FORWARD_BRIDGE
case of networkUpdateState in commit b61db335 (first in release
1.2.14) resulted in networks based on macvtap bridge mode being
erroneously marked as inactive any time libvirtd was restarted.
The problem is that the original code had differentiated between a
network using tap devices to connect to an existing host-bridge device
(forward mode of VIR_NETWORK_FORWARD_BRIDGE and a non-NULL
def->bridge), and one using macvtap bridge mode to connect to any
ethernet device (still forward mode VIR_NETWORK_FORWARD_BRIDGE, but
null def->bridge), but the changed code assumed that all networks with
VIR_NETWORK_FORWARD_BRIDGE were tap + host-bridge networks, so a null
def->bridge was interpreted as "inactive".
This patch restores the original code in networkUpdateState
The adminDispatchConnectListServers() function is generated by
our great perl script. However, it has a tiny flaw: if
adminConnectListServers() it calls fails, the control jumps onto
cleanup label where we try to free any list of servers built so
far. However, in the loop @i is unsigned (size_t) while @nresults
is signed (int). Currently, it does no harm because of the check
for @result being non-NULL. But if that ever changes in the
future, this bug will be hard to chase.

Instead of forcing the values for the unbind_from_stub, remove_slot
and reprobe properties, look up the actual device and use that when
calling virPCIDeviceReattach().
This ensures the device is restored to its original state after
reattach: for example, if it was not bound to any driver before
detach, it will not be bound forcefully during reattach.
We would be just fine looking up the information in pcidevs most
of the time; however, some corner cases would not be handled
properly, so look up the actual device instead.
After this patch, ownership of virPCIDevice instances is very easy
to keep track of: for each host PCI device, the only instance that
actually matters is the one inside one of the bookkeeping list.
Whenever some operation needs to be performed on a PCI device, the
actual device is looked up first; when this is not the case, a
comment explains the reason.
Unmanaged devices, as the name suggests, are not detached
automatically from the host by libvirt before being attached to a
guest: it's the user's responsability to detach them manually
beforehand. If that preliminary step has not been performed, the
attach operation can't complete successfully.
Instead of relying on the lower layers to error out with cryptic
messages such as
error: Failed to attach device from /tmp/hostdev.xml
error: Path '/dev/vfio/12' is not accessible: No such file or directory
prevent the situation altogether and provide the user with a more
useful error message.
Unmanaged devices are attached to guests in two steps: first,
the device is detached from the host and marked as inactive;
subsequently, it is marked as active and attached to the guest.
If the daemon is restarted between these two operations, we lose
track of the inactive device.
Steps 5 and 6 of virHostdevPreparePCIDevices() already subtly
take care of this situation, but some planned changes will make
it so that's no longer the case. Plus, explicit is always better
than implicit.
This will skip few steps from qemuProcessStart in order to create only

Until now, the libxl driver ignored any <hap> setting in domain XML
and deferred to libxl, which enables hap if not specified. While
this is a good default, it prevents disabling hap if desired.
This change allows disabling hap with <hap state='off'/>. hap is
explicitly enabled with <hap/> or <hap state='on/>. Absense of <hap>
retains current behavior of deferring default state to libxl.
hap is enabled by default in xm and xl config and usually only
specified when it is desirable to disable hap (hap = 0). Change
the xm,xl <-> xml converter to behave similarly. I.e. only
produce 'hap = 0' when <hap state='off'/> and vice versa.

yet provide a knob to disable it, extend the <hap> feature with a
'state=on|off' attribute, similar to <pvspinlock> and <vmport> features.
In the absence of <hap>, the hypervisor default (on) is used. <hap>
without the state attribute would be the same as <hap state='on'/> for
backwards compatibility. And of course <hap state='off'/> disables hap.

If a <graphics type='spice'> has no port nor tlsPort set, the generated
QEMU command line will contain -spice port=0.
This is later going to be ignored by spice-server, but it's better not
to add it at all in this situation.
As an empty -spice is not allowed, we still need to append port=0 if we
did not add any other argument.
The end goal is to avoid adding -spice port=0,addr=127.0.0.1 to QEMU command
line when no SPICE port is specified in libvirt XML.
Currently, the code relies on port=xx to always be present, so subsequent
args can be unconditionally appended with a leading ','. Since port=0
will no longer be added in a subsequent commit, we append a ',' to every
arg instead of prepending, and remove the last one before adding it to
the arg list.
It's just a combination of AddImplicitControllers, and AddConsoleCompat.
Every caller that wants ImplicitControllers also wants the ConsoleCompat
AFAICT, so lump them together. We also need it for future patches.
Judging by how the whitelist has skewed quite far from the original
error message, I think it's better to just drop these.
If someone wants to revive this check I suggest implementing it on
a per-HV driver basis with PostParse callbacks.
If we expose this information, which is one byte in every PCI config
file, we let all mgmt apps know whether the device itself is an endpoint
or not so it's easier for them to decide whether such device can be
passed through into a VM (endpoint) or not (*-bridge).

Commit id '4f846170' added printing of a new field 'part_separator';

This patch adjusts the logic to appropriately format the device path and
if there the part_separator attribute.
Commit 'ef2ab8fd' moved just the virDomainConfNWFilterTeardown and left
the logic to save/restore the current error essentially doing nothing
in the error path for qemuBuildCommandLine. So move it to where it
was meant to be.
Although the original code would reset the filter on command creation
errors after building the network command portion and commit 'ef2ab8fd'
altered that logic, the teardown is called during qemuProcessStop from
virDomainConfVMNWFilterTeardown and that code has the save/restore
last error logic, so just allow that code to handle the teardown rather
than running it twice. The qemuProcessStop would be called in the failure
path of qemuBuildCommandLine.

The problem with the original virLogParseOutputs method was that the way it
parsed the input, walking the string char by char and using absolute jumps
depending on the virLogDestination type, was rather complicated to read.
This patch utilizes virStringSplit method twice, first time to filter out any
spaces and split the input to individual log outputs and then for each
individual output to tokenize it by to the parts according to our
PRIORITY:DESTINATION?(:DATA) format. Also, to STREQLEN for matching destination
was replaced with virDestinationTypeFromString call.
In order to refactor the ugly virLogParseOutputs method, this is a neat way of
finding out whether the destination type (in the form of a string) user
provided is a valid one. As a bonus, if it turns out it is valid, we get the
actual enum which will later be passed to any of virLogAddOutput methods right
away.

These comments explain the difference between a virPCIDevice
instance used for lookups and an actual device instance; some
information is also provided for specific uses.
virHostdevGetPCIHostDeviceList() is similar but does not filter out
devices that are not in the active list; that said, we are looking
up the device in the active list just a few lines after anyway, so
we might as well just keep a single function around.
This also helps stress the fact the objects contained in pcidevs are
only for looking up the actual devices, which is something later
commits will make even more explicit.
We're in the hostdev module, so mgr is not an ambiguous name, and
in fact it's already used in some cases. Switch all the code over.
Take the chance to shorten declaration of
virHostdevIsPCINodeDeviceUsedData structures.
When we want to look up a device in a device list and we already
have the IDs from another source, we can simply use
virPCIDeviceListFindByIDs() instead of creating a temporary device
object.
If 'last_processed_hostdev_vf != -1' is false then, since the
loop counter 'i' starts at 0, 'i <= last_processed_hostdev_vf'
can't possibly be true and the loop body will never be executed.
However, since 'i' is unsigned and 'last_processed_hostdev_vf'
is signed, we can't just get rid of the check completely; what
we can do is move it outside of the loop to avoid checking its
value on every iteration and cluttering the actual loop
condition.

Add new function to manage adding the serial device options to the
command line removing that task from the mainline qemuBuildCommandLine.
Using const virDomainDef causes collateral damage in other called APIs
which need to make the similar adjustment

Alter the logic slightly to make !nsmartcards check first so that remainder
of the code is less indented.

Let's call it modern_ret_as_list as opposed to single_ret_as_list. The
latter was able to return list of things. However the new, more modern,
version came and it is used since listAllDomains till nowadays in
ListServers.

We were using parentheses for grouping admin|remote even though we didn't
need to capture what's in it. That caused some changes to be greater
than needed and, to be honest, some confusion as well. Let's use it as
it should be used. It'll also make future changes more consistent.

For now it does not matter which ones we return as the code is similarly
complex, however it will fit in with other constructs in the future,
mainly when we will be able to generate dispatch helpers.

virHashForEach() returns 0 if everything went nice, so our session
daemon was timing out even when there was a client connected.

This serves the same purpose as VIR_ERR_NO_xxx where xxx is any object
that API can be called upon. Only this particular one is used for
daemon's servers.

Since servers know their name, there is no need to supply such
information twice. Also defeats inconsistencies.

At first I did not want to do this, but after trying to implement some
newer feaures in the admin API I realized we need that to make our lives
easier. On the other hand they are not saved redundantly and the
virNetServer objects are still kept in a hash table.

Function virAdmConnectListServers() forgot to check for flags at all,
virAdmConnectOpen() on the other hand checked them but did no dispatch
the error. virCheckFlags() should be used only when there should be no
other thing done after erroring out and since they are used on different
places then just public API, they cannot dispatch errors. So let's use
virCheckFlagsGoto instead.

Add new function to manage adding the -fsdev options to the
command line removing that task from the mainline qemuBuildCommandLine.
Alter the code slightly to perform the !caps and fsdev failure check
up front.
Since both qemuBuildFSStr and qemuBuildFSDevStr are local, make them
static and fix their prototypes to use the const virDomainDef as well.
Make some minor formatting changes for long lines.

Also since using const virDomainDef in new function, that means other
functions called needed to change their usage.
