This reverts commit afee47d07c521b4bb10a12e253a29363d16ab8f0, which
added support to lxc for the "peer" attribute in domain interface <ip>
elements.
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.
This reverts commit 690969af9ccdf9b2012b97af0462bae8e312c9c9, which
added the domain config parts to support a "peer" attribute in domain
interface <ip> elements.

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

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.
Similarly to what commit 714080791778 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'.

When the domain definition describes a machine with NUMA, setting the
maximum vCPU count via the API might lead to an invalid config.
Add a check that will forbid this until we add more advanced cpu config
capabilities.

Instead of setting the default qemu stdio logging approach in
virQEMUDriverConfigLoadFile set it in virQEMUDriverConfigNew so that
it's properly set even when the config is not present.

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.

Add virDomainObjGetShortName() and use it. For now that's used in one
place, but we should expose it so that future patches can use it.

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.

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.
This function - in contrast with qemuBuildCommandLine - merely
constructs our internal command representation of a domain. This
is then later compared against expected output. Or, this function
is used also in virConnectDomainXMLToNative(). But due to a copy
paste error this function, just like its image - has @forceFips
argument that if enabled forces FIPS, otherwise mimics FIPS state
in the host. If FIPS is enabled or forced the generated command
line is different to state in which FIPS is disabled. Problem is,
while this could be desired in the virConnectDomainXMLToNative()
case, this is undesirable in the test suite as it will produce
unpredicted results.
Solution to this is to rename argument to @enableFips to
specifically tell whether we expect command line to be build in
either of fashions and make virConnectDomainXMLToNative()
implementation fetch FIPS state and pass it to
qemuProcessCreatePretendCmd().

This error message was too specific, based on the incorrect assumption
that any error was cause by auto-added bridges:
failed to create PCI bridge on bus 2: too many devices
with fixed addresses
In practice you can't know if a bridge with an index <= the bus it's
connecting to was added automatically, or if it was a mistake in
explicit config, and the auto-add problem is going to be dealt with in
a different way in an upcoming patch. The new message is this:
PCI Controller at index 1 (0x01) has "
bus='0x02', but bus must be <= index
(note that index is given in both decimal and hex because it is
formatted as decimal in the XML, but bus is formatted as hex, and
displaying the hex value of index makes it easier to see the problem
when index > 9 (which will often be the case with PCIe, since most
controllers only have a single port, not 32 slots as with standard
PCI)).

We can't use eg. @sysconfdir@ directly in the .pod file, because
pod2man(1) will interpret that as a variable name and format it
accordingly.
Instead, we use eg. SYSCONFDIR and use a subsequent sed(1) call
to turn it into the expected @sysconfdir@.
After this commit, all man pages are generated using the same two
steps:
1. Process a source $command.pod file with pod2man(1) to obtain
a valid man page in $command.$section.in
2. Process $command.$section.in with sed(1) to obtain the final
man page in $command.$section
The values are currently limited to LLONG_MAX which causes some
problems. QEMU conveniently changed their maximum to 1e15 (1 PB) which
is enough for some time and we need to adapt to that so that we don't
throw "Unknown error" messages. Strictly limiting these values actually
fixes some corner case values (off-by-one checks in QEMU probably).
Since values out of the new specified range do not overflow anything,
change the type of error as well.

According to the dnsmasq manpage, the netmask for IPv4 address ranges
will be auto-deteremined from the interface dnsmasq is listening on,
but it can't do this for IPv6 for some reason - it instead assumes a
network prefix of 64 for all IPv6 address ranges. If this is
incorrect, dnsmasq will refuse to give out an address to clients,
instead logging this message:
dnsmasq-dhcp[2380]: no address range available for DHCPv6 request via virbr0
The solution is for libvirt to add ",$prefix" to all IPv6 dhcp-range
arguments when building the dnsmasq.conf file.
