pciDeviceListSteal(pcidevs, dev) removes dev from pcidevs reducing
the length of pcidevs, so moving onto what was the next dev is wrong.
Instead callers should pop entry 0 repeatedly until pcidevs is empty.

I was testing a virsh patch, and wanted to see if I had passed the
flags I thought. But with LIBVIRT_DEBUG in the environment, I just
saw:
14:24:52.359: 15022: debug : virDomainSnapshotNum:15586 : dom=0xc9c180, (VM: name=rhel_6-64, uuid=48f8e8e7-e14f-0e14-02f0-ce71997bdcab),
including a trailing space. This fixes the issues.
* src/libvirt.c: Log flag parameters, even if currently unused.
(VIR_DOMAIN_DEBUG_0): Drop trailing comma in log.
(VIR_DOMAIN_DEBUG_1): Split guts into...
(VIR_DOMAIN_DEBUG_2): ...new macro.
Knowing whether 'virsh start' will resume a saved image or do
a fresh boot is useful enough to expose via 'virsh list'.
Also, translate the state column.
* tools/virsh.c (cmdList): add --managed-save flag
* tools/virsh.pod (list): Document it.
Based on a suggestion by Miklos Vajna.
* src/qemu/qemu_monitor_json.c: Handle error "CommandNotFound" and
report the error.
* src/qemu/qemu_monitor_text.c: If a sub info command is not found,
it prints the output of "help info", for other commands,
"unknown command" is printed.
Without this patch, libvirt always report:
An error occurred, but the cause is unknown
This patch was adapted from a patch by Osier Yang <jyang@redhat.com> to
break out detection of unrecognized text monitor commands into a separate
function.

s/VIR_ERR_NO_SUPPORT/VIR_ERR_OPERATION_INVALID/
Special case is changes on lxcDomainInterfaceStats, if it's not
implemented on the platform, prints error like:
lxcError(VIR_ERR_OPERATION_INVALID, "%s",
_("interface stats not implemented on this platform"));
As the function is supported by driver actually, error like
VIR_ERR_NO_SUPPORT is confused.
Now, bad key-code in send-key can cause segmentation fault in libvirt.
(example)
% virsh send-key --codeset win32 12
error: End of file while reading data: Input/output error
This is caused by overrun at scanning keycode array.
Fix it.

Systemtap 1.2 <sys/sdt.h> tried to expand STAP_PROBE3 into an
initialization:
volatile __typeof__(arg) foo = arg;
but that fails if arg was declared as 'char arg[100]'.
Rather than make all callers to PROBE deal with the stupidity
of <sys/sdt.h>, we instead make PROBE cast away the problem.
Some of this preprocessor abuse copies ideas in src/libvirt.c.
* daemon/libvirtd.h (PROBE): Add casts to all arguments, using...
(VIR_ADD_CASTS, VIR_ADD_CAST, VIR_ADD_CAST2, VIR_ADD_CAST3)
(VIR_ADD_CAST_EXPAND, VIR_ADD_CAST_PASTE, VIR_COUNT_ARGS)
(VIR_ARG5, PROBE_EXPAND): New macros.
Reported by Wen Congyang.
Without this patch, invoking 'virsh >file 2>&1' results in
error messages appearing before normal output, even if they
occurred later in time than the normal output (since stderr
is unbuffered, but stdout waits until a full buffer).
* tools/virsh.c (print_job_progress, vshError): Flush between
stream transitions.
* tests/undefine: Test it.
Often, we want to use XPath functions on the just-parsed document;
fold this into the parser function for convenience.
* src/util/xml.h (virXMLParseHelper): Add argument.
(virXMLParseStrHelper, virXMLParseFileHelper): Delete.
(virXMLParseCtxt, virXMLParseStringCtxt, virXMLParseFileCtxt): New
macros.
* src/libvirt_private.syms (xml.h): Remove deleted functions.
* src/util/xml.c (virXMLParseHelper): Add argument.
(virXMLParseStrHelper, virXMLParseFileHelper): Delete.
ACK was given too soon. According to the code, the xm driver is
only used for inactive domains, and has no notion of an active
domain, thus, it cannot support undefine of a running domain.
The real fix for xen needs to be in the unified driver and/or
the xend level.
This reverts commit 49186deda6.
* src/qemu/qemu_monitor_text.c: BALLOON_PREFIX was defined as
"balloon: actual=", which cause "actual=" is stripped early before
the real parsing. This patch changes BALLOON_PREFIX into "balloon: ",
and modifies related functions, also renames
"qemuMonitorParseExtraBalloonInfo" to "qemuMonitorParseBalloonInfo",
as after the changing, it parses all the info returned by "info balloon".
Although we are flushing cache after some critical writes (e.g.
volume creation), after some others we do not (e.g. volume cloning).
This patch fix this issue. That is for volume cloning, writing
header of logical volume, and storage wipe.
When spice_tls is set but listen_tls is not, we don't initialize
GnuTLS library. So any later gnutls call (e.g. during migration,
where we initialize a certificate) will access uninitialized GnuTLS
internal structs and throws an error.
Although, we might now initialize GnuTLS twice, it is safe according
to the documentation:
This function can be called many times,
but will only do something the first time.
This patch creates 2 functions: virNetTLSInit and virNetTLSDeinit
with respect to written above.
I did 'git add .' while in the middle of 'make syntax-check', and
it picked up a temporary file that should not be committed.
* .gitignore: Ignore sc_* from syntax check.
Regression introduced in commit b7e5ca4.
Mingw lacks kill(), but we were only using it for a sanity check;
so we can go with one less check.
Also, on OOM error, this function should outright fail rather than
claim that the pid file was successfully read.
* src/util/virpidfile.c (virPidFileReadPathIfAlive): Skip kill
call where unsupported, and report error on OOM.
If a client had initiated a stream abort, it will have a call
waiting for a reply in the queue. If more data continues to
arrive on the stream, the abort command could mistakenly get
signalled as complete. Remove the code from async data processing
that looked for waiting calls. Add a sanity check to ensure no
async call can ever be marked as needing a reply
* src/rpc/virnetclient.c: Ensure async data packets can't
trigger a reply
The I/O event callback processes incoming packets first, and then
does outgoing packets. If the incoming packet caused the stream to
close, then the attempt to process outgoing data resulted in an
error. This caused libvirt to then send an error back to the client,
but the stream had already been stopped. This confused the client
since it sees 2 error events.
* daemon/stream.c: Don't attempt read if stream is closed
A virsh command like:
migrate --live --copy-storage-all Guest qemu+ssh://user@host/system
--persistent --verbose
shows
Migration: [ 0 %]
during the storage copy and does not start counting
until the ram transfer starts
Fix this by scraping optional disk transfer status, and adding it
into the progress meter.
Call me lazy, but:
virsh qemu-monitor-command dom --hmp info status
is nicer than:
virsh qemu-monitor-command dom --hmp 'info status'
* tools/virsh.c (cmdQemuMonitorCommand): Allow multiple arguments,
for convenience.
Otherwise the device will still be bound to pci-stub driver even
it's set as "managed=yes" when do detaching. Of course, it won't
triger any driver reprobing too.
