Both disk->src->shared and disk->src->readonly can't be modified when
changing disk source for floppy and cdrom drives since both arguments
are passed as arguments of the disk rather than the image in qemu.
Historically these fields have only two possible values since they are
represented as XML thus we need to ignore if user did not provide them
and thus we are treating them as false.
If qemu doesn't support DEVICE_TRAY_MOVED event the code that attempts
to change media would attempt to re-eject the tray even if it wouldn't
be notified when the tray opened. Add a capability bit and skip retrying
for old qemus.
Empty floppy drives start with tray in "open" state and libvirt did not
refresh it after startup. The code that inserts media into the tray then
waited until the tray was open before inserting the media and thus
floppies could not be inserted.

These are wrappers over virStreamRecv and virStreamSend so that
users have to care about nothing but writing data into / reading
data from a sink (typically a file). Note, that these wrappers
are used exclusively on client side as the daemon has slightly
different approach. Anyway, the wrappers allocate this buffer and
use it for intermediate data storage until the data is passed to
stream to send, or to the client application. So far, we are
using 64KB buffer. This is enough, but suboptimal because server
can send messages up to VIR_NET_MESSAGE_LEGACY_PAYLOAD_MAX bytes
big (262120B, roughly 256KB). So if we make the buffer this big,
a single message containing the data is sent instead of four,
which is current situation. This means lower overhead, because
each message contains a header which needs to be processed, each
message is processed roughly same amount of time regardless of
its size, less bytes need to be sent through the wire, and so on.
Note that since server will never sent us a stream message bigger
than VIR_NET_MESSAGE_LEGACY_PAYLOAD_MAX there's no point in
sizing up the client buffer past this threshold.

There are two functions on the client that handle incoming stream
data. The first one virNetClientStreamQueuePacket() is a low
level function that just processes the incoming stream data from
the socket and stores it into an internal structure. This happens
in the client event loop therefore the shorter the callbacks are,
the better. The second function virNetClientStreamRecvPacket()
then handles copying data from internal structure into a client
provided buffer.
Change introduced in this commit makes just that: new queue for
incoming stream packets is introduced. Then instead of copying
data into intermediate internal buffer and then copying them into
user buffer, incoming stream messages are queue into the queue
and data is copied just once - in the upper layer function
virNetClientStreamRecvPacket(). In the end, there's just one
copying of data and therefore shorter event loop callback. This
should boost the performance which has proven to be the case in
my testing.

The man page says: "(Re)-Connect to the hypervisor. When the shell is
first started, this is automatically run with the URI parameter
requested by the "-c" option on the command line." However, if you run:
virsh -c 'test://default' 'connect; uri'
the output will not be 'test://default'. That's because the 'connect'
command does not care about any virsh-only related settings and if it is
run without parameters, it connects with @uri == NULL. Not only that
doesn't comply to what the man page describes, but it also doesn't make
sense. It also means you aren't able to reconnect to whatever you are
connected currently.
So let's fix that in both virsh and virt-admin add a test case for it.

This reverts commit 6e244c659f, which
added support to qemu for the "peer" attribute in domain interface <ip>

It's being removed temporarily for the release of libvirt 1.3.4
because the feature doesn't work, and there are concerns that it may
need to be modified in an externally visible manner which could create
backward compatibility problems.

FD passing APIs like CreateXMLWithFiles or OpenGraphicsFD will leak
file descriptors. The user passes in an fd, which is dup()'d in
virNetClientProgramCall. The new fd is what is transfered to the
server virNetClientIOWriteMessage.
Once all the fds have been written though, the parent msg->fds list
is immediately free'd, so the individual fds are never closed.
This closes each FD as its send to the server, so all fds have been
closed by the time msg->fds is free'd.

If we want to delete all disks for container or vm
we should make a loop from 0 to NumberOfDisks and always
use zero index in PrlVmCfg_GetHardDisk to get disk handle.
When we delete first disk after that numbers of other disks
will be changed, start from 0 to NumberOfDisks-1.
That's why we should always use zero index.
Add ULL suffix to all related operands of << or shift will give
all zeros instead of correct mask.

Similarly to what commit 7140807917 did with some internal paths,
clear vnc socket paths that were generated by us. Having such path in
the definition can cause trouble when restoring the domain. The path is
generated to the per-domain directory that contains the domain ID.
However, that ID will be different upon restoration, so qemu won't be
able to create that socket because the directory will not be prepared.
To be able to migrate to older libvirt, skip formatting the socket path
in migratable XML if it was autogenerated. And mark it as autogenerated
if it already exists and we're parsing live XML.
Best viewed with '-C'.

If the domain name is long enough, the timestamp can prolong the
filename for automatic coredump to more than the filesystem's limit.
Simply shorten it like we do in other places. The timestamp helps with
the unification, but having the ID in the name won't hurt.

Currently we only allow /dev/random and /dev/hwrng as host input
for <rng><backend model='random'/> device. This was added after
various upstream discussions in commit 4932ef45
However this restriction has generated quite a few complaints over
the years, so a new discussion was initiated:
http://www.redhat.com/archives/libvir-list/2016-April/msg00987.html
Several people suggested removing the restriction, and nobody really
spoke up to defend it. So this patch drops the path restriction
entirely

If you compile a client --without-polkit, and connect to a URI that needs
polkit auth, the connection will fail with:
$ ./tools/virsh --connect qemu+ssh://crobinso@machine/system
error: failed to connect to the hypervisor
error: authentication failed: unsupported authentication type 2
This is because the client side portion of the polkit handling is
compiled out. However, nothing polkit specific is actually required
of the client.
Fix that error by unconditionally compiling the basic polkit client
handling.

If libvirt-daemon-config-network is installed while libvirtd is already
running, the daemon doesn't notice the network. Users then have to
manually restart libvirtd (or reboot) to pick up the network.
Instead let's trigger a daemon restart when the package is first installed.
Then the default network is available immediately if libvirtd was already
running.

Since commit 9b77ce63f1 we create a .in file while building all
man pages, including those in the tools/ directory; update the
ignore patterns to take this change into account.
The new ignore patterns are generic enough that we can get rid of
a few existing ones as well.
All top-level functions have been moved to this class.
On top of that, the app.warning() method has been defined,
so that calls to it - already present in rebuild() - can
actually succeed.
Since commit d195cffa2e, both $(srcdir) and $(abs_builddir)
are passed to the apibuild.py script; however, since the
former is a relative path and the latter an absolute one, the
script might not be able to detect whether they point to the
same location.
Pass both as relative paths to avoid the issue.
Introduce the final accessor's to _virSecretObject data and move the
structure from virsecretobj.h to virsecretobj.c
The virSecretObjSetValue logic will handle setting both the secret
value and the value_size. Some slight adjustments to the error path
over what was in secretSetValue were made.
Additionally, a slight logic change in secretGetValue where we'll
check for the internalFlags and error out before checking for
and erroring out for a NULL secret->value. That way, it won't be
obvious to anyone that the secret value wasn't set rather they'll
just know they cannot get the secret value since it's private.
Move and rename the secretRewriteFile, secretSaveDef, and secretSaveValue
from secret_driver to virsecretobj
Need to make some slight adjustments since the secretSave* functions
called secretEnsureDirectory, but otherwise mostly just a move of code.
Move and rename secretDeleteSaved from secret_driver into virsecretobj and
split it up into two parts since there is error path code that looks to
just delete the secret data file
Move to secret_conf.c and rename to virSecretLoadAllConfigs. Also includes
moving/renaming the supporting virSecretLoad, virSecretLoadValue, and
virSecretLoadValidateUUID.
This patch replaces most of the guts of secret_driver.c with recently
added secret_conf.c APIs in order manage secret lists and objects
using the hashed virSecretObjList* lookup API's.
Add function to return a "match" filtered list of secret objects. This
function replaces the guts of secretConnectListAllSecrets.
Need to also move and make global virSecretUsageIDForDef since it'll
be used by both secret_driver.c and secret_conf.c
Add the functions to add/remove elements from the hashed secret obj list.
These will replace secret_driver functions secretAssignDef and secretObjRemove.
The virSecretObjListAddLocked will perform the necessary lookups and
decide whether to replace an existing hash entry or create a new one.
This includes setting up the configPath and base64Path as well as being
able to support the caller's need to restore from a previous definition
in case something goes wrong in the caller.
New API's including unlocked and Locked versions in order to be able
to use in either manner.
Support for searching hash object lists instead of linked lists will
replace existing secret_driver functions secretFindByUUID and
secretFindByUsage
Move virSecretObj from secret_driver.c to virsecretobj.h
To support being able to create a hashed secrets list, move the
virSecretObj to virsecretobj.h so that the code can at least find
the definition.
This should be a temporary situation while the virsecretobj.c code
is patched in order to support a hashed secret object while still
having the linked list support in secret_driver.c. Eventually, the
goal is to move the virSecretObj into virsecretobj.c, although it
is notable that the existing model from which virSecretObj was
derived has virDomainObj in src/conf/domain_conf.h and virNetworkObj
in src/conf/network_conf.h, so virSecretObj wouldn't be unique if
it were to remain in virsecretobj.h Still adding accessors to fetch
and store hashed object data will be the end goal.
Add definitions and infrastucture in virsecretobj.c to create and
handle a hashed virSecretObj and virSecretObjList including the class,
object, lock setup, and disposal API's. Nothing will call these yet.
This infrastructure will replace the forward linked list logic
within the secret_driver, eventually.
Our distcheck is broken. Well, it works but only by pure chance.
When wireshark plugin is enabled, we try to query which path
should the plugin be installed into. Firstly, we try to ask
pkg-config as some releases of wireshark already sets
corresponding variable in their pkg-config files. However, if we
obtained no value from there we try to construct the path on our
own. Based on our observations it usually is:
$libdir/wireshark/plugins/$version/.
Now, the problem is in the way we are deciding whether we have
obtained the plugin directory from pkg-config or not. Simply
said, we are checking wrong variable. The variable we are
checking has never been set, thus in our test is empty and
therefore we will always construct the plugin dir path on our
own, regardless of its presence in the pkg-config file.
To make things worse, after fixing this problem, VPATH build was
broken as it now tried to install plugin into correct directory.
Yes, this is problem, because --prefix was not honoured and
everything but the plugin was installed into given prefix. I've
managed to resolve this issue by replacing plugin dir prefix with
our own. So when doing regular installation (our prefix ==
wireshark prefix), nothing changes. When doing VPATH build &
installation plugin is installed into correctly prefixed dir.
