* tools/virsh.c: cmdCd was returning a 0 on success and -1 on error,
  when the rest of the code expected a TRUE on success and a
  FALSE on error.

No functional change. These all generated compiler warnings which, for
some reason weren't converted to errors by
--enable-compiler-warnings=error.

* tools/virsh.c:
  - change return type from int to void on two functions that don't
    return a value.
  - remove unused variables/labels from two functions
  - eliminate non-literal format strings
  - typecast char* into xmlChar* when calling
  - xmlParseBalancedChunkMemory

When the daemon libvirtd restarts, a connected virsh gets a SIGPIPE
and dies. This change the behaviour to try to reconnect if the
signal was received or command error indicated a connection or RPC
failure. Note that the failing command is not restarted.

* tools/virsh.c: catch SIGPIPE signals as well as connection related
  failures, add some automatic reconnection code and appropriate error
  messages.

* global: patch created by running:
for f in $(git ls-files '*.[ch]') ; do
    cppi $f > $f.t && mv $f.t $f
done

With N_() in place, we can use it for a smaller file.

* doc/api-extension/0008-Step-8-of-8-Add-virsh-support.patch:
Replace all uses of gettext_noop with N_.
* tools/virsh.c: Likewise, throughout the file.

It is a bad idea to call gettext on an already-translated
string.  In cases where a string must be translated separately
from where it is exposed to xgettext, the gettext manual
recommends the idiom of N_() wrapping gettext_noop for
marking the string.

* src/internal.h (N_): Fix definition to match gettext manual.
* tools/virsh.c: (cmdHelp, cmdList, cmdDomstate, cmdDominfo)
(cmdVcpuinfo, vshUsage): Replace incorrect use of N_ with _.
(vshCmddefHelp): Likewise.  Mark C format strings appropriately.

gcc warns:
virsh.c:1879: warning: '0' flag ignored with '-' flag in gnu_printf format

* tools/virsh.c (cmdDomjobinfo): Delete useless flag.

This supports cancellation of jobs for the QEMU driver against
the virDomainMigrate, virDomainSave and virDomainCoreDump APIs.
It is not yet supported for the virDomainRestore API, although
it is desirable.

* src/qemu/qemu_driver.c: Issue 'migrate_cancel' command if
  virDomainAbortJob is issued during a migration operation
* tools/virsh.c: Add a domjobabort command

Introduce support for  virDomainGetJobInfo in the QEMU driver. This
allows for monitoring of any API that uses the 'info migrate' monitor
command. ie virDomainMigrate, virDomainSave and virDomainCoreDump

Unfortunately QEMU does not provide a way to monitor incoming migration
so we can't wire up virDomainRestore yet.

The virsh tool gets a new command 'domjobinfo' to query status

* src/qemu/qemu_driver.c: Record virDomainJobInfo and start time
  in qemuDomainObjPrivatePtr objects. Add generic shared handler
  for calling 'info migrate' with all migration based APIs.
* src/qemu/qemu_monitor_text.c: Fix parsing of 'info migration' reply
* tools/virsh.c: add new 'domjobinfo' command to query progress

* tools/virsh.c (cmdPoolDiscoverSources): Always initialize srcSpec.
Otherwise, clang would report that srcSpec could be used uninitialized
in the call to virConnectFindStoragePoolSources.

* tools/virsh.c: Just "return;", not "return NULL;".

Only API calls trigger the error callback, which is required for
proper virsh error reporting. Since we use non API functions from
util/, make sure we properly report these errors.

Fixes lack of error message from 'virsh create idontexit.xml'

* tools/virsh.c (cmdCPUBaseline): Remove declarations of unused
variables, p and cur.

Signed-off-by: NJiri Denemark <jdenemar@redhat.com>

* tools/virsh.c: call virStoragePoolFree() in the main path too

* tools/virsh.c (cmdCPUBaseline): Also free "buffer" and "list" upon OOM.

* tools/virsh.c (cmdCPUBaseline): Add an explicit "return" statement
after the "no_memory:" label.

* tools/virsh.c: add a command to compute a CPU baseline based on
  multiple CPU definitions in an XML chunk
* tools/virsh.pod: add it to the man page

There is no real leak here, but Coverity-Prevent thinks there is.
It does not see that while there are four ways to return from
vshCommandGetToken with VSH_TK_END, none of them results in allocation
of a result.
* tools/virsh.c (vshCommandParse): Add a (currently) useless VIR_FREE,
to ensure that we never leak when vshCommandGetToken returns VSH_TK_END.

It was used for error reporting only.

Change all virsh commands that invoke virDomain{Attach,Detach}Device()
to use virDomain{Attach,Detach}DeviceFlags() instead.

Add a "--persistent" flag to these virsh commands, allowing user to
specify that the domain persisted config be modified as well.

V2: Only invoke virDomain{Attach,Detach}DeviceFlags() if
"--persistent" flag is specified.  Otherwise invoke
virDomain{Attach,Detach}Device() to retain current behavior.

* src/qemu/qemu_monitor_text.c (qemuMonitorTextGetAllPCIAddresses):
Use %s.
* src/storage/storage_backend_iscsi.c (virStorageBackendCreateIfaceIQN):
Likewise.
* tools/virsh.c (cmdSecretSetValue): Likewise.

Revert commit 7aee2293 since it
is mistakenly adding an extra parameter to virsh that does not
belong there.

virsh uses other parts of the internal API already, so use VIR_FREE also.

As Paul Jenner pointed out all other statistics commands use the
singular form

* tools/virsh.c: rename dommemstats to dommemstat as well as function
  name and associated structures

Define a new command 'dommemstats' to report domain memory statistics.  The
output format is inspired by 'domblkstat' and 'domifstat' and consists of
tag/value pairs, one per line.  The command can complete successfully and
print no output if virDomainMemoryStats is supported by the driver, but not
the guest operating system.

Sample output:
swap_in 0
swap_out 0
major_fault 54
minor_fault 58259
unused 487680
available 502472

All stats referring to a quantity of memory (eg. all above except major and
minor faults) represent the quantity in KBytes.

* tools/virsh.c: implements the new command

* tools/virsh.c: provide a way to us teh new API with virsh

* tools/virsh.c (vshCommandParse): Avoid double-free of "tkdata".
Set it to NULL immediately after free in the (cmd == NULL) case,
just as in the other case, in case the final free(tkdata) is
triggered by a syntax error.

This patch fixes the problem reported in:

https://bugzilla.redhat.com/show_bug.cgi?id=509306

The bug reporter says that vol-delete does not support the --pool
option, but that's not the case in the current head.  This patch makes
vol-path behave the same way as vol-delete

* tools/virsh.c: Modified vol-path to use the same logic as vol-delete,
  allowing the syntax: virsh vol-path --pool testdirpool testvol0

This is trivial for QEMU since you just have to not stop the vm before
starting the dump.  And for Xen, you just pass the flag down to xend.

* include/libvirt/libvirt.h.in (virDomainCoreDumpFlags): Add VIR_DUMP_LIVE.
* src/qemu/qemu_driver.c (qemudDomainCoreDump): Support live dumping.
* src/xen/xend_internal.c (xenDaemonDomainCoreDump): Support live dumping.
* tools/virsh.c (opts_dump): Add --live. (cmdDump): Map it to VIR_DUMP_LIVE.

This patch adds the --crash option (already present in "xm dump-core")
to "virsh dump".  virDomainCoreDump already has a flags argument, so
the API/ABI is untouched.

* include/libvirt/libvirt.h.in (virDomainCoreDumpFlags): New flag for
  CoreDump
* src/test/test_driver.c (testDomainCoreDump): Do not crash
  after dump unless VIR_DUMP_CRASH is given.
* src/qemu/qemu_driver.c (qemudDomainCoreDump): Shutdown the domain
  instead of restarting it if --crash is passed.
* src/xen/xend_internal.c (xenDaemonDomainCoreDump): Support --crash.
* tools/virsh.c (opts_dump): Add --crash.
  (cmdDump): Map it to flags for virDomainCoreDump and pass them.

This adds a new flag, VIR_MIGRATE_PAUSED, that mandates pausing
the migrated VM before starting it.

* include/libvirt/libvirt.h.in (virDomainMigrateFlags): Add VIR_MIGRATE_PAUSED.
* src/qemu/qemu_driver.c (qemudDomainMigrateFinish2): Handle VIR_MIGRATE_PAUSED.
* tools/virsh.c (opts_migrate): Add --suspend. (cmdMigrate): Handle it.
* tools/virsh.pod (migrate): Document it.

Replace free(virBufferContentAndReset()) with virBufferFreeAndReset().
Update documentation and replace all remaining calls to free() with
calls to VIR_FREE(). Also add missing calls to virBufferFreeAndReset()
and virReportOOMError() in OOM error cases.

The 'virsh console' command did not check if the domain was
already running before attempting to fetch the XML and extract
the console PTY path. This caused a slightly unhelpful / misleading
error message for the user. The explicit check ensures the user
gets an explicit 'domain is not running' message.

* tools/virsh.c: Validate that state != VIR_DOMAIN_SHUTOFF in
  virsh console command

* daemon/libvirtd.c tools/virsh.c: Steve Grubb <sgrubb@redhat.com> found
  a few more issues

All drivers have copy + pasted inadequate error reporting which wraps
util.c:virGetHostname. Move all error reporting to this function, and improve
what we report.

Changes from v1:
  Drop the driver wrappers around virGetHostname. This means we still need
  to keep the new conn argument to virGetHostname, but I think it's worth
  it.

This patch adds the flag VIR_INTERFACE_XML_INACTIVE to
virInterfaceGetXMLDesc's flags. When it is*not* set (the default), the
live interface info will be returned in the XML (in particular, the IP
address(es) and netmask(s) will be retrieved by querying the interface
directly, rather than  reporting what's in the config file). The
backend of this is in netcf's ncf_if_xml_state() function.

* configure.in libvirt.spec.in: requires netcf >= 0.1.3
* include/libvirt/libvirt.h.in: adds flag VIR_INTERFACE_XML_INACTIVE
* src/conf/interface_conf.c src/interface/netcf_driver.c src/libvirt.c:
  update the parsing and backend routines accordingly
* tools/virsh.c: change interface edit to inactive definition and
  adds the inactive flag for interface dump

* tools/virsh.c: call to vshError() containing 'doexit' parameter
  sneaked in after said parameter was removed
