d62e51f86b virsh: add support for virConnectListAllDomains and clean up cmdList
This patch makes use of the newly added api virConnectListAllDomains()
to list domains in virsh.

Virsh now represents lists of domains using an internal structure
vshDomainList. This structure contains the virDomainPtr list as provided
by virConnectListAllDomains() and the count of domains in the list.

For backwards compatibility, the function vshDomainListCollect was added
that tries to enumerate the domains using the new API and if the API is
not supported falls back to the older approach with the two list
functions.  The helper function also simulates filtering by all
currently supported flags added with virConnectListAllDomains().

This patch also cleans up the "list" command handler to use the new
helpers and adds new command line flags to make use of filtering.

e4cfe5f699 storage: Set the perms if the pool target already exists for fs pools
The comment says:

/* Now create the final dir in the path with the uid/gid/mode
 * requested in the config. If the dir already exists, just set
 * the perms.
 */

However, virDirCreate is only invoked if the target path doesn't
exist yet (which is opposite with the comment), or the uid from
the config is not -1 (I don't understand why, think it's just
another mistake). And the result is the perms of the pool won't
be changed if one tries to build the pool with different perms
again.

Besides these logic error fix, if no uid and gid are specified in
the config, the practical used uid, gid are reflected.

question in fact exists.

e3fe4102c1 snapshot: require existence before returning success
Blindly returning success is misleading if the object no longer
exists; it is a bit better to check for existence up front before
returning information about that object.  This pattern matches the
fact that most of our other APIs check for existence as a side
effect prior to getting at the real piece of information being
queried.

* src/esx/esx_driver.c (esxDomainIsUpdated, esxDomainIsPersistent):
Add existence checks.
* src/vbox/vbox_tmpl.c (vboxDomainIsPersistent)

33dc8cf018 drivers: Implement virListAllDomains for drivers using virDomainObj
This patch adds support for listing all domains into drivers that use
the common virDomainObj implementation: libxl, lxc, openvz, qemu, test,
uml, vmware.

For drivers that don't support managed save images the guests are
treated as if they had none, so filtering guests that do have such an
image on this driver succeeds and produces 0 results.

37bb0447bb list: add virDomainListAllSnapshots API
There was an inherent race between virDomainSnapshotNum() and
virDomainSnapshotListNames(), where an additional snapshot could
be created in the meantime, or where a snapshot could be deleted
before converting the name back to a virDomainSnapshotPtr.  It
was also an awkward name: the function operates on domains, not
domain snapshots.  virDomainSnapshotListChildrenNames() suffered
from the same inherent race, although its naming was nicer.

This patch makes things nicer by grabbing a snapshot list
atomically, in the format most useful to the user.

35ae18f3c6 snapshot: expose new flags in virsh
Previously, to get the name of all snapshots with children, it was
necessary to get the name of all snapshots and then remove the
name of leaf snapshots.  This is racy, and somewhat inefficient
compared to planned API additions.  We can emulate --no-metadata on
0.9.5-0.9.12, but for now, there is no emulation of --no-leaves.

* tools/virsh.c (cmdSnapshotList): Add new options --no-leaves and
--no-metadata.

5873f2e2da snapshot: add additional filters when getting lists
It turns out that one-bit filtering makes it hard to select the inverse
set, so it is easier to provide filtering groups.  For back-compat,
omitting all bits within a group means the group is not used for
filtering, and by definition of a group (each snapshot matches exactly
one bit within the group, and the set of bits in the group covers all
snapshots), selecting all bits also makes the group useless.

Unfortunately, virDomainSnapshotListChildren defined the bit
VIR_DOMAIN_SNAPSHOT_LIST_DESCENDANTS as an expansion rather than a
filter, so we cannot make it part of a filter group, so that bit
(and its counterpart VIR_DOMAIN_SNAPSHOT_LIST_ROOTS for
virDomainSnapshotList) remains a single control bit.

* include/libvirt/libvirt.h.in (virDomainSnapshotListFlags): Add a
couple more flags.

830d035ff5 domain_conf: fix possible memory leak
Until now, it was possible to crash libvirtd when defining domain with
channel device with missing source element.

When creating new virDomainChrDef, target.port is set to -1, but
unfortunately it is an union with addresses that virDomainChrDefFree
tries to free in case the deviceType is channel. Having the port set
to -1 is intended, however the cleanest way to get around the problems
with the crash seems to be renumbering the VIR_DOMAIN_CHR_CHANNEL_
target types to cover new NONE type (with value 0) being the default
(no target type yet).

06d4a1e429 snapshot: use metaroot node to simplify management
This idea was first suggested by Daniel Veillard here:
https://www.redhat.com/archives/libvir-list/2011-October/msg00353.html

Now that I am about to add more complexity to snapshot listing, it
makes sense to avoid code duplication and special casing for domain
listing (all snapshots) vs. snapshot listing (descendants); adding
a metaroot reduces the number of code lines by having the domain
listing turn into a descendant listing of the metaroot.

Note that this has one minor pessimization - if we are going to list
ALL snapshots without filtering, then virHashForeach is more efficient
than recursing through the child relationships; restoring that minor
optimization will occur in the next patch.

* src/conf/domain_conf.h (_virDomainSnapshotObj)

(virDomainSnapshotDropParent): Drop unused parameter.

747f64eeaf lib: Add public api to enable atomic listing of guest
This patch adds a new public api that lists domains. The new approach is
different from those used before. There are key points to this:

1) The list is acquired atomically and contains both active and inactive
domains (guests). This eliminates the need to call two different list
APIs, where the state might change in between the calls.

2) The returned list consists of virDomainPtrs instead of names or ID's
that have to be converted to virDomainPtrs anyways using separate calls
for each one of them. This is more convenient and saves hypervisor calls.

3) The returned list is auto-allocated. This saves a lot of hassle for
the users.

4) Built in support for filtering. The API call supports various
filtering flags that modify the output list according to user needs.

Available filter groups:
    Domain status:
    VIR_CONNECT_LIST_DOMAINS_ACTIVE, VIR_CONNECT_LIST_DOMAINS_INACTIVE

    Domain persistence:
    VIR_CONNECT_LIST_DOMAINS_PERSISTENT,
    VIR_CONNECT_LIST_DOMAINS_TRANSIENT

    Domain state:
    VIR_CONNECT_LIST_DOMAINS_RUNNING, VIR_CONNECT_LIST_DOMAINS_PAUSED,
    VIR_CONNECT_LIST_DOMAINS_SHUTOFF, VIR_CONNECT_LIST_DOMAINS_OTHER

    Existence of managed save image:
    VIR_CONNECT_LIST_DOMAINS_MANAGEDSAVE,
    VIR_CONNECT_LIST_DOMAINS_NO_MANAGEDSAVE

    Auto-start option:
    VIR_CONNECT_LIST_DOMAINS_AUTOSTART,
    VIR_CONNECT_LIST_DOMAINS_NO_AUTOSTART

    Existence of snapshot:
    VIR_CONNECT_LIST_DOMAINS_HAS_SNAPSHOT,
    VIR_CONNECT_LIST_DOMAINS_NO_SNAPSHOT

5) The python binding returns a list of domain objects that is very neat
to work with.

The only problem with this approach is no support from code generators
so both RPC code and python bindings had to be written manually.

76d397b0d3 snapshot: new virsh function factored from snapshot-list
This patch is based on the fallback code out of cmdSnapshotList,
with tweaks to keep the snapshot objects around rather than just
their name, and to remove unwanted elements before returning.
It looks forward to a future patch when we add a way to list all
snapshot objects at once, and the next patch will simplify
cmdSnapshotList to take advantage of this factorization.

* tools/virsh.c (vshSnapshotList, vshSnapshotListFree): New functions.

350583c859 build: hoist qemu dependence on yajl to configure
Commit 6e769eba made it a runtime error if libvirt was compiled
without yajl support but targets a new enough qemu.  But enough
users are hitting this on self-compiled libvirt that it is worth
erroring out at compilation time, rather than an obscure failure
when trying to use the built executable.

* configure.ac: If qemu is requested and -version works, require
yajl when qemu version is new enough.
* src/qemu/qemu_capabilities.c (qemuCapsComputeCmdFlags): Add
comment.

2cd29c3107 autogen: Always abide --system
If we do ./autogen.sh && ./configure, then later try ./autogen.sh --system,
configure isn't invoked with the requested params. Instead
config.status --recheck is run.

cc004a6647 Check for errors when parsing bridge interface XML
The return status of virInterfaceDefParseBridge() was not being
checked, potentially resulting in the creation of a broken
interface.

b9852862ea Fix launch of libvirtd when DHCP snooping support is not available.
When libpcap is not available, the NWFilter driver provides a
no-op stub for the DHCP snooping initialization. This was
mistakenly returning '-1' instead of '0', so the entire driver
initialization failed
