The "if (vol->target.format != VIR_STORAGE_FILE_RAW)" check in the
createVol backend. This check is bogus because virStorageVolDefParseXML()
in conf/storage_conf.c sets target.format only if volOptions in
virStoragePoolTypeInfo has formatFromString set, and that's not the
case the zfs backend.
So the check always fails and breaks volume creation.

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

In 68b726b93c we tried to fix a mem leak. However, it
wasn't done quite well. Problem is, virNetDaemonGetServers() may
fail in which case virObjectListFreeCount() would be called with
-1 objects to free. But the number of elements is taken in
unsigned rather than signed integer.

The test can return positive value even though it should have failed. It just
returns the value parser returned, which should be flipped back to -1 if
something went wrong or the result was unexpected, but it isn't.
If caller of adminConnectListServers() pass NULL instead of servers we

Signed-off-by: Pavel Hrdina <phrdina@redhat.com>
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.

After 9c17d665fd the tap device for ethernet network type is
automatically precreated before spawning qemu. Problem is, the
qemuxml2argvtest wasn't updated and thus is failing. Because of
all the APIs that new code is calling, I had to mock a lot. Also,
since the tap FDs are labeled separately from the rest of the
devices/files I had to enable NOP security driver for the test
too.

When constructing SCSI hostdev command line for qemu, the
/sys/bus/scsi/devices/... dir is scanned. Unfortunately, even in
the tests. This is needed to determine the name of SCSI device to
passthrough to qemu, because in the domain XML we were given its
address instead. Anyway, we should not be touching live system
data in our test suite as it produced unpredictable results. The
test is regressing from 1e9a083742 on.

Ensure the code behaves properly even for situations that were not
being considered before, such as simply detaching devices from the
host without attaching them to a guest and attaching devices as
managed even though they had already been manually detached from
the host.
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
qemu CMD. Use a VIR_QEMU_PROCESS_START_PRETEND for all the qemuProcess*
functions called by this one to not modify or check host.
This new function will be used later on for XMLToNative API and also for
qemuxml2argvtest to make sure that both API and test uses the same code
as qemuProcessStart.
We need also update qemuProcessInit to wrap few lines of code with check
that VIR_QEMU_PROCESS_START_PRETEND that makes sense only for
qemuProcessStart.

Problem is that in the test any status file matching
tests/nssdata/*.status is loaded as it contains IP addresses that
are parsed. However, there's no order specified in which the
files are loaded. Therefore on different systems the order may be
different. This is then producing an unexpected results.
Instead of defining an order in which the files are loaded, make
the code that checks for missing IP addresses (or redundant ones)
cope with unordered list of addresses. The reasoning behind is
that the code doing the parsing is used in real NSS module where
we don't care for ordering.
