* daemon/libvirtd.init.in: daemon/libvirtd.init.in were not mentionned
in the usage message and if a missing or wrong argument is given it
should return 2, not 1
According to:
http://libvirt.org/html/libvirt-libvirt.html#virNetworkLookupByUUID
virNetworkLookupByUUID() expects a virConnectPtr as its first argument,
thus making it a method of the virConnect Python class.
Currently it's a method of libvirt.virNetwork.

Currently no command can be sent to a qemu process while another job is
active. This patch adds support for signaling long-running jobs (such as
migration) so that other threads may request predefined operations to be
done during such jobs. Two signals are defined so far:
- QEMU_JOB_SIGNAL_CANCEL
- QEMU_JOB_SIGNAL_SUSPEND
The first one is used by qemuDomainAbortJob.
The second one is used by qemudDomainSuspend for suspending a domain
during migration, which allows for changing live migration into offline
migration. However, there is a small issue in the way qemudDomainSuspend
is currently implemented for migrating domains. The API calls returns
immediately after signaling migration job which means it is asynchronous
in this specific case.

* autogen.sh (bootstrap_hash): New function.
Running bootstrap may update the gnulib SHA1, yet we were computing
t=$(git submodule status ...) *prior* to running bootstrap, and
then recording that sometimes-stale value in the stamp file upon
a successful bootstrap run. That would require two (lengthy!)
bootstrap runs to update the stamp file.
* src/qemu/qemu_driver.c (qemudDomainAttachSCSIDisk): The ".controller"
member is an index, and *may* be 0. As such, the commit that we're
reverting broke SCSI disk hot-plug on controller 0.
Reported by Wolfgang Mauerer.
We need to call PrepareHostdevs to determine the USB device path before
any security calls. PrepareHostUSBDevices was also incorrectly skipping
all USB devices.
* src/qemu/qemu_conf.c: add the ",readonly=on" for read-only disks
and also parse it back in qemuParseCommandLineDisk()
* tests/qemuxml2argvtest.c
tests/qemuxml2argvdata/qemuxml2argv-disk-drive-readonly-disk.args
tests/qemuxml2argvdata/qemuxml2argv-disk-drive-readonly-disk.xml:

The nodeGetInfo code was always assuming that machine had a
single NUMA node, which is not correct. The good news is that
libnuma gives us this information pretty easily, so let's
properly report it.
NOTE: With recent hardware starting to support CPU hot-add
and hot-remove, both this code and the nodeCapsInitNUMA()
code are quickly going to become obsolete. We'll have to
think of a more dynamic solution for dealing with NUMA
nodes and CPUs that can come and go at will.

If you ran virsh in interactive mode and ran a command
that virsh could not parse, it would then SEGV
on subsequent commands. The problem is that we are
freeing the vshCmd structure in the syntaxError label
at the end of vshCommandParse, but forgetting to
set ctl->cmd to NULL. This means that on the next command,
we would try to free the same structure again, leading
to badness.
* tools/virsh.c: Make sure to set ctl->cmd to NULL after
freeing it in vshCommandParse()
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
Currently if you dump the core of a qemu guest with
qemudDomainCoreDump, subsequent commands will hang
up libvirtd. This is because qemudDomainCoreDump
uses qemuDomainWaitForMigrationComplete, which expects
the qemuDriverLock to be held when it's called. This
patch does the simple thing and moves the qemuDriveUnlock
to the end of the qemudDomainCoreDump so that the driver
lock is held for the entirety of the call (as it is done
in qemudDomainSave). We will probably want to make the
lock more fine-grained than that in the future, but
we can fix both qemudDomainCoreDump and qemudDomainSave
at the same time.

The code to add job support into libvirtd caused a problem
in qemudDomainSetVcpus. In particular, a qemuDomainObjEndJob()
call was added at the end of the function, but a
corresponding qemuDomainObjBeginJob() was not. Additionally,
a call to qemuDomainObj{Enter,Exit}Monitor() was also missed
in qemudDomainHotplugVcpus(). These missing calls conspired to
cause a hang in the libvirtd process after the command was
finished. Fix this by adding the missing calls.

As previously discussed[1], this patch removes the
qemudDomainSetMaxMemory() function, since it doesn't
work. This means that instead of getting somewhat
cryptic errors, you will now get:
error: Unable to change MaxMemorySize
error: this function is not supported by the hypervisor: virDomainSetMaxMemory
Which describes the situation perfectly.

When using the JSON monitor, qemuMonitorJSONExtractCPUInfo
was returning 0 on success. Unfortunately, higher levels of
the cpuinfo code expect that it returns the number of CPUs
it found on success. This one-line patch fixes it so that
it returns the correct number. This makes "virsh vcpuinfo <domain>"
work when using the JSON monitor.

* autogen.sh (curr_status): Also include hash of bootstrap.conf
when checking for changes that require bootstrap rerun.
* cfg.mk (_update_required): Likewise.
Since cppi is not part of Fedora Core 12, the check is conditional:
without cppi, running 'make syntax-check' merely warns:
$ make sc_preprocessor_indentation
preprocessor_indentation
maint.mk: skipping test sc_preprocessor_indentation: cppi not installed
* cfg.mk (sc_preprocessor_indentation): New syntax-check rule.
(preprocessor_exempt): New macro, with first exemption.
This is a stop-gap measure to make autogen.sh rerun ./bootstrap,
(required due to recent bootstrap.conf addition) while we prepare
the fix to automatically detect the case of an updated modules list.
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.
As pointed out by eblake, I made a real hash of the
nodeinfo code with commit
aa2f6f96dd. This patch
cleans it up:
1) Do more work at compile time instead of runtime (minor)
2) Properly handle the hex digits that come from
/sys/devices/system/cpu/cpu*/topology/thread_siblings
3) Fix up some error paths that could cause SEGV
4) Used unsigned's for the cpu numbers (cpu -1 doesn't
make any sense)
Along with the recent patch from jdenemar to zero out
the nodeinfo structure, I've re-tested this on the
machines having the problems, and it seems to be good.

Having a single logrotate configuration file for all hypervisors
did not work as logrotate would get confused if an hypervisor not
supported on that platform was still listed. Simplest is to split
the logrotate as separate per hypervisor files and change the
spec file to only install the ones compiled in.
* daemon/libvirtd.lxc.logrotate.in daemon/libvirtd.qemu.logrotate.in
daemon/libvirtd.uml.logrotate.in: copy and split the original
daemon/libvirtd.logrotate.in file
* daemon/Makefile.am: update to support the different files and
cleanup in sed suggested by Eric Blake
* libvirt.spec.in: only install the relevant logrotate configs
* daemon/.gitignore: update logrotate generated list
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.
