This patch define and parse the input XML of USB redirection filter.
<devices>
...
<redirdev bus='usb' type='spicevmc'>
<address type='usb' bus='0' port='4'/>
</redirdev>
<redirfilter>
<usbdev class='0x08' vendor='0x1234' product='0xbeef' \
version='2.00' allow='yes'/>
<usbdev allow='no'/>
</redirfilter>
...
</devices>
There is no 1:1 mapping between ports and redirected devices and
qemu and spicy client couldn't decide into which usbredir ports
the client can 'plug' redirected devices. So it make sense to apply
all of filter rules global to all existing usb redirection devices.
class attribute is USB Class codes. version is bcdDevice value
of USB device. vendor and product is USB vendorId and productId.
-1 can be used to allow any value for a field. Except allow attribute
the other four are optional, default value is -1.
Add a qemu flag for USB redirection filter support.
The output:
usb-redir.chardev=chr
usb-redir.debug=uint8
usb-redir.filter=string
usb-redir.port=string
Recent spec file changes ensure that in distro situations, netcf
and libvirt will link against the same libnl in order to avoid
dumping core. But for every-day development, if you use F17 and
have the libnl3-devel headers available, libvirt was blindly
linking against libnl3 even though F17 netcf still links against
libnl1, making testing a self-built binary on F17 impossible.
By making configure a little bit smarter, we can avoid this
situation - we merely skip the probe of libnl-3 if we can prove
that netcf is still using libnl-1. I intentionally wrote the
test so that we still favor libnl-3 if netcf is not installed or
if we couldn't use ldd to determine things.
Defaults being what they are, someone will invariably complain
that our smarts were wrong. Never fear - in that case, just run
./configure LIBNL_CFLAGS=..., where the fact that you set
LIBNL_CFLAGS (even to the empty string) will go back to probing
for libnl-3, regardless of netcf's choice.
* configure.ac (LIBNL): Don't probe libnl3 if netcf doesn't use it.
I got an off-list report about a bad diagnostic:
Target network card mac 52:54:00:49:07:ccdoes not match source 52:54:00:49:07:b8
True to form, I've added a syntax check rule to prevent it
from recurring, and found several other offenders.
* cfg.mk (sc_require_whitespace_in_translation): New rule.

Based on a report by Luwen Su.
Make has a builtin operator 'undefine', and coupled with latest
automake.git, this test name ended up confusing make into thinking
the file name was meant to be used as the make operator. Renaming
the file avoids the confusion.
* tests/undefine: Rename...
* tests/virsh-undefine: ...to this.
* tests/Makefile.am (test_scripts): Use new name.

Currently qemuMonitorOpen() requires an address of the QEMU
monitor. When doing QMP based capabilities detection it is
easier if a pre-opened FD can be provided, since then the
monitor can be run on the STDIO console. Add a new API
qemuMonitorOpenFD() for such usage

Historically, the first <console> element is treated as the
alias of a <serial> device. In the virDomainDeviceInfoIterate,
This situation is not considered. It still handles the first <console>
element as another devices, which means that for console[0] with
serial targetType, it calls callback function another time.
It will cause the problem of address conflicts when assigning
spapr-vio address for serial device on pSeries guest.
For pSeries guest, the serial configuration in the xml file
is as the following:
<serial type='pty'>
<target port='0'/>
<address type='spapr-vio'/>
</serial>
Console configuration is default, the dumped xml file is as the following:
<serial type='pty'>
<source path='/dev/pts/5'/>
<target port='0'/>
<alias name='serial0'/>
<address type='spapr-vio' reg='0x30000000'/>
</serial>
<console type='pty' tty='/dev/pts/5'>
<source path='/dev/pts/5'/>
<target type='serial' port='0'/>
<alias name='serial0'/>
<address type='spapr-vio' reg='0x30000000'/>
</console>
It shows that the <console> device is the alias of serial device.
So its address is the same as the serial device. When detecting
the conflicts in the qemuAssignSpaprVIOAddress the first console
and the serial device conflicts because virDomainDeviceInfoIterate()
still handle these as two different devices, and in the qemuAssignSpaprVIOAddress(),
it will compare these two devices' addressed. If they have same address,
it will report address conflict error.
So this patch is to handle the first console which targetType is serial
as the alias of serial device to avoid address conflicts error reported.

The implementation is done manually as the generator does not support
wrapping lists of C pointers into Python objects.
python/libvirt-override-api.xml: Document
python/libvirt-override-virConnect.py:
* New file, includes implementation of listAllInterfaces.
python/libvirt-override.c: Implementation for the wrapper.
tools/virsh-interface.c:
* vshInterfaceSorter to sort interfaces by name
* vshInterfaceListFree to free the interface objects list.
* vshInterfaceListCollect to collect the interface objects, trying
to use new API first, fall back to older APIs if it's not supported.
This is not that ideal as API for other objects, as it's still
O(n). Because interface driver uses netcf APIs to manage the
stuffs, instead of by itself. And netcf APIs don't return a object.
It provides APIs like old libvirt APIs:
ncf_number_of_interfaces
ncf_list_interfaces
ncf_lookup_by_name
......
Perhaps we should further improve netcf to let it provide an API
to return the object, but it could be a later patch. And anyway,
we will still benefit from the new API for the simplification,
and no race like the old APIs.

they have had href_base prepended to them.
The remote driver first looks at the libvirt auth config file to
fill in any credentials. It then invokes the auth callback for
any remaining credentials. It was accidentally invoking the
auth callback even if there were not any more credentials
required.

If passing a 'credtype' parameter which was an empty list
to the python openAuth() API, the 'credtype' field in
the virConnectAuth struct would not be initialized. This
lead to a crash when later trying to free that field.

e5a1bee07 introduced a regression in Boxes: when Boxes is left idle
(it's still doing some libvirt calls in the background), the
libvirt connection gets closed after a few minutes. What happens is
that this code in virNetClientIOHandleOutput gets triggered:
if (!thecall)
return -1; /* Shouldn't happen, but you never know... */
and after the changes in e5a1bee07, this causes the libvirt connection
to be closed.
Upon further investigation, what happens is that
virNetClientIOHandleOutput is called from gvir_event_handle_dispatch
in libvirt-glib, which is triggered because the client fd became
writable. However, between the times gvir_event_handle_dispatch
is called, and the time the client lock is grabbed and
virNetClientIOHandleOutput is called, another thread runs and
completes the current call. 'thecall' is then NULL when the first
thread gets to run virNetClientIOHandleOutput.
After describing this situation on IRC, danpb suggested this:
11:37 < danpb> In that case I think the correct thing would be to change
'return -1' above to 'return 0' since that's not actually an
error - its a rare, but expected event
which is what this patch is doing. I've tested it against master
libvirt, and I didn't get disconnected in ~10 minutes while this
happens in less than 5 minutes without this patch.

An email came to libvir-list wondering why the git send-email command
was missing in spite of having git installed; this is due to the
send-email command being in a sub-package of the main git package.
While touching the hacking file, I thought it would be useful to 1)
indicate the location of the source (docs/hacking.html.in) in the
message at the top of HACKING, and also to make the note about running
"make check" and "make syntax-check" a bit more stern.
On RHEL 6.2, gcc 4.4.6 complains:
cc1: warning: command line option "-Wenum-compare" is valid for C++/ObjC++ but not for C
which in turn breaks a -Werror build.
Meanwhile, in Fedora 17, gcc 4.7.0, -Wenum-compare has been enhanced
to also work on C, but at the same time, it is documented that -Wall
now implicitly includes -Wenum-compare.
Therefore, it is sufficient to remove explicit checks for this option,
avoiding the warning from older gcc while still getting the
compile-time safety from newer gcc.
* m4/virt-compile-warnings.m4 (-Wenum-compare): Omit explicit check.
