The logging functions are enhanced so that immediately prior to
the first log message being printed to any output channel, the
libvirt package version will be printed.
eg
$ LIBVIRT_DEBUG=1 virsh
18:13:28.013: 17536: info : libvirt version: 0.8.7
18:13:28.013: 17536: debug : virInitialize:361 : register drivers
...
The 'configure' script gains two new arguments which can be
used as
--with-packager="Fedora Project, x86-01.phx2.fedoraproject.org, 01-27-2011-18:00:10"
--with-packager-version="1.fc14"
to allow distros to append a custom string with package specific
data.
The RPM specfile is modified so that it appends the RPM version,
the build host, the build date and the packager name.
eg
$ LIBVIRT_DEBUG=1 virsh
18:14:52.086: 17551: info : libvirt version: 0.8.7, package: 1.fc13 (Fedora Project, x86-01.phx2.fedoraproject.org, 01-27-2011-18:00:10)
18:14:52.086: 17551: debug : virInitialize:361 : register drivers
Thus when distro packagers receive bug reports they can clearly
see what version was in use, even if the bug reporter mistakenly
or intentionally lies about version/builds
* src/util/logging.c: Output version data prior to first log message
* libvirt.spec.in: Include RPM release, date, hostname & packager
* configure.ac: Add --with-packager & --with-packager-version args
QEMUD_CMD_FLAG_PCI_MULTIBUS should be set in the function
qemuCapsExtractVersionInfo()
The flag QEMUD_CMD_FLAG_PCI_MULTIBUS is used in the function
qemuBuildDeviceAddressStr(). All callers get qemuCmdFlags
by the function qemuCapsExtractVersionInfo() except that
testCompareXMLToArgvFiles() in qemuxml2argvtest.c.
So we should set QEMUD_CMD_FLAG_PCI_MULTIBUS in the function
qemuCapsExtractVersionInfo() instead of qemuBuildCommandLine()
because the function qemuBuildCommandLine() does not be called
when we attach a pci device.
tests: set QEMUD_CMD_FLAG_PCI_MULTIBUS in testCompareXMLToArgvFiles()
set QEMUD_CMD_FLAG_PCI_MULTIBUS before calling qemuBuildCommandLine()
as the flags is not set by qemuCapsExtractVersionInfo().

Win32 doesn't have a concept of signal masks so disable that
code. It is unclear how SIGINT is delivered (if at all) on
Win32, so this might further work to provide an alternative
to pthread_sigmask
* tools/virsh.c: Avoid pthread_sigmask on Win32
Quite a few hosts don't have cgroups mounted and so see warnings
from libvirt logged, which then cause bug reports, etc. Reduce
the log level to INFO so they're not visible by default
* src/qemu/qemu_driver.c: Reduce log level for cgroups
When run non-root the nwfilter driver logs error messages about
being unable to find iptables/ebtables commands (they are in
/sbin which isn't in $PATH). The nwfilter driver can't ever work
as non-root, so simply skip it entirely thus avoiding the error
messages
* src/conf/nwfilter_conf.h, src/nwfilter/nwfilter_driver.c,
src/nwfilter/nwfilter_gentech_driver.c,
src/nwfilter/nwfilter_gentech_driver.h: Pass 'bool privileged'
flag down to final driver impl

A typo s/spice/vnc/ caused parsing of the spice 'auth' data
to write into the wrong part of the struct, blowing away
other unrelated data.

Most of te VIR_INFO calls in the udev driver are only relevant
to developers so can switch to VIR_DEBUG. Failure to initialize
libpciaccess though is a fatal error
* src/node_device/node_device_udev.c: Adjust log levels
When probing machine types if the QEMU binary does not exist
we get a hard to diagnose error, due to the execve() in the
child failing
error: internal error Child process exited with status 1.
Add an explicit check so that we get
error: Cannot find QEMU binary /usr/libexec/qem3u-kvm: No such file or directory
* src/qemu/qemu_capabilities.c: Check for QEMU binary
To make it easier to investigate problems with async event
delivery, add two more debugging lines

When built as modules, the connection drivers live
in $LIBDIR/libvirt/drivers. Now we add lock manager
drivers, we need to distinguish. So move the existing
modules to 'connection-driver'
* src/Makefile.am: Move module install dir
* src/driver.c: Move module search dir
Some functionality run in virExec hooks may do I/O which
can trigger SIGPIPE. Renable SIGPIPE blocking around the
hook function
* src/util/util.c: Block SIGPIPE around hooks
The Linux kernel headers don't have a value for SCSI type 12,
but HAL source code shows this to be a 'raid'. Add workaround
for this type. Lower log level for unknown types since
this is not a fatal error condition. Include the device sysfs
path in the log output to allow identification of which device
has problems.
* src/node_device/node_device_udev.c: Add SCSI RAID type
libpciaccess has many bugs in its pci_system_init/cleanup
functions that makes calling them multiple times unwise.
eg it will double close() FDs, and leak other FDs.
* src/node_device/node_device_udev.c: Only initialize
libpciaccess once
Until now, user namespaces have not done much, but (for that
reason) have been innocuous to glob in with other CLONE_
flags. Upcoming userns development, however, will make tasks
cloned with CLONE_NEWUSER far more restricted. In particular,
for some time they will be unable to access files with anything
other than the world access perms.
This patch assumes that noone really needs the user namespaces
to be enabled. If that is wrong, then we can try a more
baroque patch where we create a file owned by a test userid with
700 perms and, if we can't access it after setuid'ing to that
userid, then return 0. Otherwise, assume we are using an
older, 'harmless' user namespace implementation.
Comments appreciated. Is it ok to do this?

The new virConnectGetSysinfo() API allows one to get the system
information associated to a connection host, providing the same
data as a guest that uses <os><smbios mode='host'/></os>, and in
a format that can be pasted into the guest and edited when using
<os><smbios mode='sysinfo'/></os>.

qemu 0.13.0 (at least as built for Fedora 14, and also backported to
RHEL 6.0 qemu) supported an older syntax for a spicevmc channel; it's

aspect), but now that we support spicevmc, we might as well target
both variants.

Add a new character device backend for virtio serial channels that
activates the QEMU spice agent on the main channel using the vdagent

Assuming a hypervisor that supports multiple smartcard devices in the
guest, this would be a valid XML description:

<source mode='bind' host='127.0.0.1' service='2001'/>
<protocol type='raw'/>

implementation, but it only supports one smartcard.)
