8077d64f96 storage: List directory volumes for dir/fs/netfs pools
Since directories can be used for <filesystem> passthrough, they are
basically storage volumes.

v2:
    Skip ., .., lost+found dirs

v3:
    Use gnulib last_component

v4:
    Use gnulib "dirname.h", not system <dirname.h>
    Don't skip lost+found

155542a57f conf: Fix incorrect spice graphic XML format on compression options
If spice graphics has no <channel> elements, the output graphics XML
is messed up. To prevent this, we need to end the <graphics> element
just before adding any compression selecting elements.

ef983dfe5a Fix sysinfo/virsh build problems on Win32
The virSysinfoIsEqual method was mistakenly inside a #ifndef WIN32
conditional.

The existing virSysinfoFormat is also stubbed out on Win32, even
though the code works without any trouble. This breaks XML output
on Win32, so the stub is removed.

virsh migrate mistakenly had some variables inside the conditional

ec5301cb85 Allow virsh to pass in a custom XML document for migration
Switch virsh migrate over to use virDomainMigrate2 and
virDomainMigrateToURI2. This is still compatible with
older libvirts, because these methods dynamically choose
whether to perform v1, v2 or v3 migration based on declared
RPC support from the libvirtd instances

Add a --xml arg which allows the user to pass in a custom
XML document. This XML document must be ABI compatible
with the current *live* XML document for the running guest
on the source host. ABI compatibility will be enforced by
any driver supporting this function

584ce634d7 lxc: Seperate domain config loading
This patch seperate the domain config loading just as qemu driver
does, first loading config of running or trasient domains, then
of persistent inactive domains. And only try to reconnect the
monitor of running domains, so that it won't always throws errors
saying can't connect to domain monitor.

And as "virDomainLoadConfig->virDomainAssignDef->virDomainObjAssignDef",
already do things like "vm->newDef = def", removed the codes
in "lxcReconnectVM" that does the same work.

80d2038d58 Issue full error messages when processing QEMU monitor I/O
Currently the QEMU monitor I/O handler code uses errno values
to report errors. This results in a sub-optimal error messages
on certain conditions, in particular when parsing JSON strings
malformed data simply results in 'EINVAL'.

This changes the code to use the standard libvirt error reporting
APIs. The virError is stored against the qemuMonitorPtr struct,
and when a monitor API is run, any existing stored error is copied
into that thread's error local

* src/qemu/qemu_monitor.c, src/qemu/qemu_monitor.h,
  src/qemu/qemu_monitor_json.c, src/qemu/qemu_monitor_text.c: Use

4454a9efc7 Don't kill QEMU process when a monitor I/O parsing error occurs
Currently whenever there is any failure with parsing the monitor,
this is treated in the same was as end-of-file (ie QEMU quit).
The domain is terminated, if not already dead.

With this change, failures in parsing the monitor stream do not
result in the death of QEMU. The guest continues running unchanged,
but all further use of the monitor will be disabled.

The VMM_FAILURE event will be emitted, and the mgmt application
can decide when to kill/restart the guest to re-gain control

  different callback for monitor EOF vs error conditions.

a6135ec1e6 Introduce a new event emitted when a virtualization failure occurs
This introduces a new domain

  VIR_DOMAIN_EVENT_ID_CONTROL_ERROR

Which uses the existing generic callback

typedef void (*virConnectDomainEventGenericCallback)(virConnectPtr conn,
                                                     virDomainPtr dom,
                                                     void *opaque);

This event is intended to be emitted when there is a failure in
some part of the domain virtualization system. Whether the domain
continues to run/exist after the failure is an implementation
detail specific to the hypervisor.

The idea is that with some types of failure, hypervisors may
prefer to leave the domain running in a "degraded" mode of
operation. For example, if something goes wrong with the QEMU
monitor, it is possible to leave the guest OS running quite
happily. The mgmt app will simply loose the ability todo various
tasks. The mgmt app can then choose how/when to deal with the
failure that occured.

97f63513ff virsh: improve schedinfo querying ability
Since we can now set just --live or --config, we also need to be
able to query that back.

a9b3a78fa6 libvirt.h: avoid regression, and document preferred name
Commit 824dcaff was a regression (thankfully unreleased) for any

ba0b5934b3 interface: new public API for network config change transactions
This is the API agreed on in:

  https://www.redhat.com/archives/libvir-list/2011-May/msg00026.html

(with a slight name change to use "...begin" rather than
"...start"). This implements transactional changes to the host network
config. When a transaction is begun with ncf_change_begin(), all other
netcf APIs will continue to work as they always have, but a snapshot
of the existing config will be taken, allowing reversion (rollback,
using ncf_change_rollback()) to the exact state of config at the time
ncf_change_begin() was called. Alternately, if it's determined that
the new changes are acceptable, ncf_change_commit() can be called,
which will eliminate the snapshot and make the changes permanent.

As a failsafe measure, if neither ncf_change_commit() or
ncf_change_rollback() is called by the next time the system reboots,
the netcf-transaction initscript will be automatically called to
rollback the changes.

8357d91b65 esx: Fix regression in absolute file name handling
Before commit 145d6cb05c (in August 2010) absolute file names
in VMX and domain XML configs were handled correctly. But this got
lost during the refactoring. The test cases didn't highlight this
problem because they have their own set of file name handling
functions. The actual ones require a real connection to an ESX
server. Also the test case functions always worked correctly.

Fix the regression and add a new in-the-wild VMX file that contains
such a problematic absolute path. Even though this test case won't
protect against new regressions.
