There is no need to have two different enums where one has the same
values as the other one with some additions.
Currently for on_poweroff and on_reboot we allow only subset of actions
that are allowed for on_crash. This was covered in parse time using
two different enums. Now to make sure that we don't allow setting
actions that are not supported we need to check it while validating
domain config.

We have couple of functions that operate over NULL terminated
lits of strings. However, our naming sucks:
virStringJoin
virStringFreeList
virStringFreeListCount
virStringArrayHasString
virStringGetFirstWithPrefix
We can do better:
virStringListJoin
virStringListFree
virStringListFreeCount
virStringListHasString
virStringListGetFirstWithPrefix

Change the virDomainChrDef to use a pointer to 'source' and allocate
that pointer during virDomainChrDefNew.
This has tremendous "fallout" in the rest of the code which mainly
has to change source.$field to source->$field.

Modeled after the qemuDomainHostdevPrivatePtr (commit id '27726d8c'),
create a privateData pointer in the _virDomainChardevDef to allow storage
of private data for a hypervisor in order to at least temporarily store
secret data for usage during qemuBuildCommandLine.
NB: Since the qemu_parse_command (qemuParseCommandLine) code is not
expecting to restore the secret data, there's no need to add code
code to handle this new structure there.

Some callers might want to pass yet another pointer to opaque
data to post parse callbacks. The driver generic one is not
enough because two threads executing post parse callback might
want to see different data (e.g. domain object pointer that
domain def belongs to).

The first argument should be const char ** instead of
char **, because this is a search function and as such it
doesn't, and shouldn't, alter the haystack in any way.
This change means we no longer have to cast arrays of
immutable strings to arrays of mutable strings; we still
have to do the opposite, though, but that's reasonable.
Allow to store driver specific data on a per-vcpu basis.
Move of the virDomainDef*Vcpus* functions was necessary as
virDomainXMLOptionPtr was declared below this block and I didn't want to
split the function headers.
a.k.a. <hostdev mode='capabilities' type='net'>.
This replaces the existing nips, ips, nroutes, and routes with a
single virNetDevIPInfo, and simplifies the code by calling that
object's parse/format/clear functions instead of open coding.
These functions all need to be called from a utility function that
must be located in the util directory, so we move them all into
util/virnetdevip.[ch] now that it exists.
Function and struct names were appropriately changed for the new
location, but all code is unchanged aside from motion and renaming.
I'm tired of mistyping this all the time, so let's do it the same all
the time (similar to how we changed all "Pci" to "PCI" awhile back).
(NB: I've left alone some things in the esx and vbox drivers because
I'm unable to compile them and they weren't obviously *not* a part of
some API. I also didn't change a couple of variables named,
e.g. "somethingIptables", because they were derived from the name of
the "iptables" command)
This is identical to type='bridge', but without the "connect to a
bridge" part, so it can be handled by using the same functions (and
often even the same cases in switch statements), after renaming
virLXCProcessSetupInterfaceBridged() to virLXCProcessInterfaceTap()
and enhancing it to skip bridge-related items when brname == NULL.
To be truly useful, we need to support setting the ip address on the
host side veth as well as guest side veth (already supported for
type='bridge'), as well as setting the peer address for both.
The <script> element (supported by type='ethernet' in qemu) isn't
supported in this patch. An error is logged at domain start time if it
is encountered. This may be changed in a later patch.
Modeled after the qemuDomainDiskPrivatePtr logic, create a privateData
pointer in the _virDomainHostdevDef to allow storage of private data
for a hypervisor in order to at least temporarily store auth/secrets
data for usage during qemuBuildCommandLine.
NB: Since the qemu_parse_command (qemuParseCommandLine) code is not
expecting to restore the auth/secret data, there's no need to add
code to handle this new structure there.

Ensure any assignments to onCrash use VIR_DOMAIN_LIFECYCLE_CRASH_* defs and

Upping an interface for no reason and not configuring it is a cardinal sin.
With the default addrgenmode if eui64 it sticks a link-local address to the
interface. That is not good, as NetworkManager would see an address configured,
assume the interface is already configured and won't touch it iself and the
interface might stay unconfigured until the end of the days.

As there are two possible approaches to define a domain's memory size -
one used with legacy, non-NUMA VMs configured in the <memory> element
and per-node based approach on NUMA machines - the user needs to make
sure that both are specified correctly in the NUMA case.
To avoid this burden on the user I'd like to replace the NUMA case with
automatic totaling of the memory size. To achieve this I need to replace
direct access to the virDomainMemtune's 'max_balloon' field with
two separate getters depending on the desired size.
The two sizes are needed as:
1) Startup memory size doesn't include memory modules in some
hypervisors.
2) After startup these count as the usable memory size.
Note that the comments for the functions are future aware and document
state that will be present after a few later patches.
There was a mess in the way how we store unlimited value for memory
limits and how we handled values provided by user. Internally there
were two possible ways how to store unlimited value: as 0 value or as
VIR_DOMAIN_MEMORY_PARAM_UNLIMITED. Because we chose to store memory
limits as unsigned long long, we cannot use -1 to represent unlimited.
It's much easier for us to say that everything greater than
VIR_DOMAIN_MEMORY_PARAM_UNLIMITED means unlimited and leave 0 as valid
value despite that it makes no sense to set limit to 0.
Remove unnecessary function virCompareLimitUlong. The update of test
is to prevent the 0 to be miss-used as unlimited in future.

As virDomainNumatuneSet now doesn't allocate the virDomainNuma object
any longer it's not necessary to pass the pointer to a pointer to store
the object as it will not change any longer.
While touching the parameter definitions I've also changed the name of
the parameter to "numa".
This patch adds back the virDomainDef typedef into domain_conf and
makes all the numatune_conf functions independent of any virDomainDef

There were numerous places where numatune configuration (and thus
domain config as well) was changed in different ways. On some
places this even resulted in persistent domain definition not to be
stable (it would change with daemon's restart).
In order to uniformly change how numatune config is dealt with, all
the internals are now accessible directly only in numatune_conf.c and
outside this file accessors must be used.

Since there was already public virDomainNumatune*, I changed the
private virNumaTune to match the same, so all the uses are unified and
public API is kept:
s/vir\(Domain\)\?Numa[tT]une/virDomainNumatune/g
then shrunk long lines, and mainly functions, that were created after
that:
sed -i 's/virDomainNumatuneMemPlacementMode/virDomainNumatunePlacement/g'
And to cope with the enum name, I haad to change the constants as
well:
s/VIR_NUMA_TUNE_MEM_PLACEMENT_MODE/VIR_DOMAIN_NUMATUNE_PLACEMENT/g
Last thing I did was at least a little shortening of already long
name:
s/virDomainNumatuneDef/virDomainNumatune/g

The problem with VLAN is that the user still has to manually create the
vlan interface on the host. Then the generated configuration will use
it as a nerwork hostdev device. So the generated configurations of the
following two fragments are equivalent (see rhbz#1059637).
lxc.network.type = phys
lxc.network.link = eth0.5
lxc.network.type = vlan
lxc.network.link = eth0
lxc.network.vlan.id = 5
