1f7560e25d maint: enforce whitespace on shell scripts
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.

b9a2552d2a Use configured CPU model if possible
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.

53c4f9fa1c Support removing features when converting data to 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.

e07314f4c1 Deal with CPU models in []
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.

9fbb810cf4 Fix initial VCPU pinning in qemu driver
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.

8274993f29 Make avahi startup more robust.
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.

b1fab0c21c esx: Don't treat an empty root snapshot list as error
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.

c8f4dcca6a Extend fwall-drv interface and call functions via interface
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.

8f342c6f9a build: avoid compiler warning
According to GCC, ATTRIBUTE_UNUSED means that an attribute _might_

of when we know it is unused.

8b3a89c486 Install nwfilter xml files from source directory.
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.

5d4009b0d1 Don't ship generated python/libvirt.? files.
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.

Jiri Denemark
070da02fb5 Introduce virCheckFlags for consistent flags checking
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.

c4896d378b Fix CDROM media change for QEMU when using -device syntax
Disk devices in QEMU have two parts, the guest device and the host
backend driver. Historically these two parts have had the same

constant

efd4ee7871 Remove code from JSON monitor for commands that won't be ported
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.

41b087198d nwfilter: fix tear down order and consolidate functions
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
