Noticed because virt-pki-validate was very inconsistent on
using tabs vs. 8 spaces, sometimes mixing both paradigms on
a single line.
'git diff -b' shows significant changes only in cfg.mk.
* cfg.mk (sc_TAB_in_indentation): Add a few files.
* daemon/libvirtd.init.in: Avoid tabs.
* tools/virt-pki-validate.in: Likewise.
Adds ability to provide a preferred CPU model for CPUID data decoding.
Such model would be considered as the best possible model (if it's
supported by hypervisor) regardless on number of features which have to
be added or removed for describing required CPU.
So far, when CPUID data were converted into CPU model and features, the
features can only be added to the model. As a result, when a guest asked
for something like "qemu64,-svm" it would get a qemu32 plus a bunch of
additional features instead.
This patch adds support for removing feature from the base model.
Selection algorithm remains the same: the best CPU model is the model
which requires lowest number of features to be added/removed from it.
Qemu committed a patch which list some CPU names in [] when asked for
supported CPUs (qemu -cpu ?). Yet, it needs such CPUs to be passed
without those square braces. When probing for supported CPU models, we
can just strip the square braces and pretend we have never seen them.
First, inital VCPU pinning is set correctly but then it is reset by
assigning qemu process to a new cgroup (which contains all CPUs). It's
easily fixed by swapping these two actions.
If the hostname of the current virtualization machine
could not be resolved, then libvirtd would fail to
start. However, for disconnected operation (on a laptop,
for instance) the hostname may very legitimately not
be resolvable. This patch makes it so that if we can't
resolve the hostname, avahi doesn't fail, it just uses
a less useful MDNS string.

An empty root snapshot list was considered as error condition. Creating a
new snapshot would fail if the domain didn't have snapshots yet, because
the snapshot-create function tries to lookup the list of existing snapshots
in order to verify that the snapshot name is unique. This fails if the
domain doesn't have snapshots yet.
Removing the NULL check from esxVI_LookupRootSnapshotTreeList fixes this.
I am moving some of the eb/iptables related functions into the interface
of the firewall driver and am making them only accessible via the driver's
interface. Otherwise exsiting code is adapted where needed. I am adding one
new function to the interface that checks whether the 'basic' rules can be
applied, which will then be used by a subsequent patch.
According to GCC, ATTRIBUTE_UNUSED means that an attribute _might_
be unused, not _must_ be unused. Therefore, it is easier to
blindly mark a variable, than to try and do preprocessor limiting
of when we know it is unused.
* src/remote/remote_driver.c (remoteAuthenticate): Mark attribute
as potentially unused.

During an out-of-tree build, the current working directory is the build
directory. Since the FILTERS are static and not modified or
auto-generated during the build process, they need to be explicitly
fetched from the source directory during install.
Prefix the files with $(srcdir), which gets expanded to the absolute or
relative path to the source directory, even when duing out-of-tree
builds.

libvirt.c and libvirt.h are auto-generated files. Mentioning their names
in *_SOURCES includes them in the distribution. During an out-of-tree
build these shipped files are included instead of the auto-generated
version, potentially breaking the build (as it happend in 0.8.0, because
the shipped libvirt.h was missing the declaration for
'libvirt_virDomainUpdateDeviceFlags')
Use the nodist_*_SOURCES automake variable instead.

The generator code was totally wrong for the virDomainSnapshot
APIs, not generating the wrapper class, and giving methods the
wrong names
* generator.py: Set metadata for virDomainSnapshot type & APIs
* libvirt-override-api.xml, libvirt-override.c: Hand-code the
virDomainSnapshotListNames glue layer
The initial boot of VMs uses -device for NICs where available. The
corresponding monitor command is device_add, but the network hotplug
code was still using device_del by mistake.
* src/qemu/qemu_driver.c: Use device_add for NIC hotplug where
available
If either of the getfd or host_net_add monitor commands return
any text, this indicates an error condition. Don't ignore this!
* src/qemu/qemu_monitor_text.c: Report errors for getfd and
host_net_add
The 'device_del' command expects a parameter called 'id' but we
were passing 'config'.
* src/qemu/qemu_monitor_json.c: Fix device_del command parameter
The idea is that every API implementation in driver which has flags
parameter should first call virCheckFlags() macro to check the function
was called with supported flags:
virCheckFlags(VIR_SUPPORTED_FLAG_1 |
VIR_SUPPORTED_FLAG_2 |
VIR_ANOTHER_SUPPORTED_FLAG, -1);
The error massage which is printed when unsupported flags are passed
looks like:
invalid argument in virFooBar: unsupported flags (0x2)
Where the unsupported flags part only prints those flags which were
passed but are not supported rather than all flags passed.
strtok_r will be used in the ESX driver to replace scanf-based code.
MinGW lacks strtok_r, so we need gnulib to provide it, but until now
strtok_r was licensed LGPL3.
Based on a warning from coverity. The safe* functions
guarantee complete transactions on success, but don't guarantee
freedom from failure.
* src/util/util.h (saferead, safewrite, safezero): Add
ATTRIBUTE_RETURN_CHECK.

* daemon/event.c (virEventHandleWakeup): Ignore read failure.
Disk devices in QEMU have two parts, the guest device and the host
backend driver. Historically these two parts have had the same
"unique" name. With the switch to using -device though, they now
have separate names. Thus when changing CDROM media, for guests
using -device syntax, we need to prepend the QEMU_DRIVE_HOST_PREFIX
constant
* src/qemu/qemu_conf.c, src/qemu/qemu_conf.h: Add helper function
qemuDeviceDriveHostAlias() for building a host backend alias
* src/qemu/qemu_driver.c: Use qemuDeviceDriveHostAlias() to determine
the host backend alias for performing eject/change commands in the
monitor
The device_add command was added in JSON mode in a way I didn't
expect. Instead of passing the normal device string to the JSON
command:
{ "execute": "device_add", "arguments": { "device": "ne2k_pci,id=nic.1,netdev=net.1" } }
We need to split up the device string into a full JSON object
{ "execute": "device_add", "arguments": { "driver": "ne2k_pci", "id": "nic.1", "netdev": "net.1" } }
* src/qemu/qemu_conf.h, src/qemu/qemu_conf.c: Rename the
qemuCommandLineParseKeywords method to qemuParseKeywords
and export it to monitor
* src/qemu/qemu_monitor_json.c: Split up device string into
a JSON object for device_add command
The parameter for the qemuMonitorDeviceDel() is a device alias,
not a device config string. Rename the parameter reflect this
and avoid confusion to readers.
* src/qemu/qemu_monitor.c, src/qemu/qemu_monitor.h,
src/qemu/qemu_monitor_json.c, src/qemu/qemu_monitor_json.h,
src/qemu/qemu_monitor_text.c, src/qemu/qemu_monitor_text.h:
Rename devicestr to devalias in qemuMonitorDeviceDel()
The QEMU developers have stated that they will not be porting
the commands 'pci_add', 'pci_del', 'usb_add', 'usb_del' to the
JSON mode monitor, since they're obsoleted by 'device_add'
and 'device_del'. libvirt has (untested) code that would have
supported those commands in theory, but since we already use
device_add/del where available, there's no need to keep the
legacy stuff anymore.
The text mode monitor keeps support for all commands for sake
of historical compatability.
* src/qemu/qemu_monitor_json.c: Remove 'pci_add', 'pci_del',
'usb_add', 'usb_del' commands
To ensure that patches in the RPM don't break any functionality
it is neccessary to run the test suites during build. It currently
has 3 tests disabled
- daemon-conf: this is totally broken, since it relies on
being able to resolve the 'libvirt' group & being able to
resolve hostnames at daemon startup. This isn't possible
in a mock build root
- seclabeltest: fails to initialize selinux in the mock
build root. Possibly fixable
- nodeinfotest: broken on s390 + ppc - this is a real bug
* libvirt.spec.in: Add a %check section, with 3 tests
temporarily disabled
The QEMU driver is mistakenly calling directly into the text
mode monitor for the domain memory stats query.
* src/qemu/qemu_driver.c: Replace qemuMonitorTextGetMemoryStats with
qemuMonitorGetMemoryStats
* src/qemu/qemu_monitor.c, src/qemu/qemu_monitor.h: Add the new
wrapper for qemuMonitorGetMemoryStats
* src/qemu/qemu_monitor_json.c, src/qemu/qemu_monitor_json.h: Add
qemuMonitorJSONGetMemoryStats implementation
Instead of reporting VIR_ERR_INTERNAL_ERROR use the more specific
VIR_ERR_CONFIG_UNSUPPORTED
* src/qemu/qemu_conf.c: Report VIR_ERR_CONFIG_UNSUPPORTED for
unsupported video adapters
To avoid race-conditions, the tear down of a filter has to happen before
the tap interface disappears and another tap interface with the same
name can re-appear. This patch tries to fix this. In one place, where
communication with the qemu monitor may fail, I am only tearing the
filters down after knowing that the function did not fail.
I am also moving the tear down functions into an include file for other
drivers to reuse.
