Nearly all of the methods in src/util/util.h have error codes that
must be checked by the caller to correct detect & report failure.
Add ATTRIBUTE_RETURN_CHECK to ensure compile time validation of
this
* daemon/libvirtd.c: Add explicit check on return value of virAsprintf
* src/conf/domain_conf.c: Add missing check on virParseMacAddr return
value status & report error
* src/network/bridge_driver.c: Add missing OOM check on virAsprintf
and report error
* src/qemu/qemu_conf.c: Add missing check on virParseMacAddr return
value status & report error
* src/security/security_selinux.c: Remove call to virRandomInitialize
that's done in libvirt.c already
* src/storage/storage_backend_logical.c: Add check & log on virRun
return status
* src/util/util.c: Add missing checks on virAsprintf/Run status
* src/util/util.h: Annotate all methods with ATTRIBUTE_RETURN_CHECK
if they return an error status code
* src/vbox/vbox_tmpl.c: Add missing check on virParseMacAddr
* src/xen/xm_internal.c: Add missing checks on virAsprintf
* tests/qemuargv2xmltest.c: Remove bogus call to virRandomInitialize()
The current virDomainObjListPtr object stores domain objects in
an array. This means that to find a particular objects requires
O(n) time, and more critically acquiring O(n) mutex locks.
The new impl replaces the array with a virHashTable, keyed off
UUID. Finding a object based on UUID is now O(1) time, and only
requires a single mutex lock. Finding by name/id is unchanged
in complexity.
In changing this, all code which iterates over the array had
to be updated to use a hash table iterator function callback.
Several of the functions which were identically duplicating
across all drivers were pulled into domain_conf.c
* src/conf/domain_conf.h, src/conf/domain_conf.c: Change
virDomainObjListPtr to use virHashTable. Add a initializer
method virDomainObjListInit, and rename virDomainObjListFree
to virDomainObjListDeinit, since its not actually freeing
the container, only its contents. Also add some convenient
methods virDomainObjListGetInactiveNames,
virDomainObjListGetActiveIDs and virDomainObjListNumOfDomains
which can be used to implement the correspondingly named
public API entry points in drivers
* src/libvirt_private.syms: Export new methods from domain_conf.h
* src/lxc/lxc_driver.c, src/opennebula/one_driver.c,
src/openvz/openvz_conf.c, src/openvz/openvz_driver.c,
src/qemu/qemu_driver.c, src/test/test_driver.c,
src/uml/uml_driver.c, src/vbox/vbox_tmpl.c: Update all code
to deal with hash tables instead of arrays for domains
Implementation of tunnelled migration, using a Unix Domain Socket
on the qemu backend. Note that this requires very new versions of
qemu (0.10.7 at least) in order to get the appropriate bugfixes.

Rename virStorageVolFormatFileSystem to virStorageFileFormat and
move to src/util/storage_file.[ch]
* src/Makefile.am: add src/util/storage_file.[ch]
* src/conf/storage_conf.[ch]: move enum from here ...
* src/util/storage_file.[ch]: .. to here
* src/libvirt_private.syms: update To/FromString exports
* src/storage/storage_backend.c, src/storage/storage_backend_fs.c,
src/vbox/vbox_tmpl.c: update for above changes
* src/vbox/vbox_tmpl.c: minor bug in selecting the graphics type. if the
graphics type was desktop it was assumed that display is set for it,
and thus crashed on strdup. Also adds a number of missing OOM checks.
* src/vbox/vbox_driver.c: remove some old 2.5 switches and plug the
3.0 driver
* src/vbox/vbox_V3_0.c src/vbox/vbox_CAPI_v3_0.h: the driver for
VirtualBox 3.0
* src/vbox/vbox_tmpl.c: handle the new driver and add event support
* src/Makefile.am: plug in the new module
When we hot-plug a disk device into a qemu guest, we need to retain its
PCI address so that it can be removed again later. Currently, we do
retain the slot number, but not across libvirtd restarts.
Add <state devaddr="xxxx:xx:xx"/> to the disk device XML config when the
VIR_DOMAIN_XML_INTERNAL_STATUS flag is used. We still don't parse the
domain and bus number, but the format allows us to do that in future.
* src/domain_conf.h: replace slotnum with pci_addr struct, add helper
for testing whether the address is valid
* src/domain_conf.c: handle formatting and parsing the address
* src/qemu_driver.c: store the parsed slot number as a full PCI address,
and use this address with the pci_del monitor command
* src/vbox/vbox_tmpl.c: we're debug printing slotnum here even though
it can never be set, just delete it
by running this command:
git ls-files -z | xargs -0 perl -pi -0777 -e 's/\n\n+$/\n/'
This is in preparation for a more strict make syntax-check
rule that will detect trailing blank lines.
* src/vbox/vbox_driver.c src/vbox/vbox_tmpl.c: changes in
VirtualBox driver version detection and move informations
from a global variable into a driver structure, patch by Pritesh
Kothari.
