virStreamAbort is needed when the caller wishes to terminate
the stream early, not when virStreamSend fails.
* qemu/qemu_driver.c: Fix calling of virStreamAbort during
tunnelled migration
The code for tunnelled migration was added in a dedicated method,
but the native migration code is still inline in the top level
qemudDomainMigratePerform() API. Move the native code out into
a dedicated method too to make things more maintainable.
* src/qemu/qemu_driver.c: Pull code for performing a native
QEMU migration out into separate method
The code for tunnelled migration wierdly required the app to pass
a NULL 'dconn' parameter, only to have to use virConnectOpen
itself shortly thereafter to get a 'dconn' object. Remove this
bogus check & require the app to always pas 'dconn' as before
* src/libvirt.c: Require 'dconn' for virDomainMigrate calls again
and remove call to virConnectOpen
Since virMigratePrepareTunnel() is used for migration over the
native libvirt connection, there is never any need to pass the
target URI to this method.
* daemon/remote.c, src/driver.h, src/libvirt.c, src/libvirt_internal.h,
src/qemu/qemu_driver.c, src/remote/remote_driver.c,
src/remote/remote_protocol.c, src/remote/remote_protocol.h,
src/remote/remote_protocol.x: Remove 'uri_in' parameter from
virMigratePrepareTunnel() method
Move the VIR_DRV_FEATURE* constants into libvirt_internal.h
since these flags are indicating whether APIs in the
libvirt_internal.h file are supported by a driver
* src/driver.h: Remove VIR_DRV_FEATURE* constants
* src/libvirt_internal.h: Add VIR_DRV_FEATURE* constants, using
an enum instead of #define
* src/internal.h: pull in libvirt_internal.h
* src/lxc/lxc.conf: new configuration file, there is currently one
tunable "log_with_libvirtd" that controls whether an lxc controller will
log only to the container log file, or whether it will honor libvirtd's
log output configuration. This provides a way to have libvirtd and its
children log to a single file. The default is to log to the container
log file.
* src/Makefile.am libvirt.spec.in: add the new file
* src/lxc/lxc_conf.[ch] src/lxc/lxc_driver.c: read the new log value
from the configuration file and pass the log informations when
starting up a container.
* src/lxc/lxc_driver.c src/lxc/lxc_controller.c: before launching the
lxc controller, have the lxc driver query the log settings and setup
envp[]. This provides the advantage of honoring the actual log
configuration instead of only what had been set in the environment.
The lxc controller now simply has to call virLogSetFromEnv().
When configuring logging settings, keep more information about the
output destination. Add accessors to retrieve the filter and output
settings in the original string form; this to be used to set up
environment for a child process that also logs.
* src/util/logging.[ch]: add virLogGetFilters and virLogGetOutputs
accessors and modify the internals (including virLogDefineOutput())
to save the data needed for the accessors
* src/util/util.[ch]: Add virFileAbsPath() function to ensure an
absolute path for a potentially realtive path.
* src/libvirt_private.syms: add it in libvirt private symbols
* docs/drvqemu.html.in: include documentation for AppArmor sVirt
confinement
* examples/apparmor/TEMPLATE examples/apparmor/libvirt-qemu
examples/apparmor/usr.lib.libvirt.virt-aa-helper
examples/apparmor/usr.sbin.libvirtd: example templates and
configuration files for SVirt Apparmor when using KVM/QEmu
* configure.in: look for AppArmor and devel
* src/security/security_apparmor.[ch] src/security/security_driver.c
src/Makefile.am: add and plug the new driver
* src/security/virt-aa-helper.c: new binary which is used exclusively by
the AppArmor security driver to manipulate AppArmor.
* po/POTFILES.in: registers the new files
* tests/Makefile.am tests/secaatest.c tests/virt-aa-helper-test:
tests for virt-aa-helper and the security driver, secaatest.c is
identical to seclabeltest.c except it initializes the 'apparmor'
driver instead of 'selinux'
The patch implements the missing memory control APIs for lxc, i.e.,
domainGetMaxMemory, domainSetMaxMemory, domainSetMemory, and improves
domainGetInfo to return proper amount of used memory via cgroup.
* src/libvirt_private.syms: Export virCgroupGetMemoryUsage
and add missing virCgroupSetMemory
* src/lxc/lxc_driver.c: Implement missing memory functions
* src/util/cgroup.c, src/util/cgroup.h: Add the function
to get used memory
When James Morris originally submitted his sVirt patches (as seen in
libvirt 0.6.1), he did not require on disk labelling for
virSecurityDomainRestoreImageLabel. A later commit[2] changed this
behavior to assume on disk labelling, which halts implementations for
path-based MAC systems such as AppArmor and TOMOYO where
vm->def->seclabel is required to obtain the label.
* src/security/security_driver.h src/qemu/qemu_driver.c
src/security/security_selinux.c: adds the 'virDomainObjPtr vm'
argument back to *RestoreImageLabel
While running make check, I noticed that it was actually using
the virsh binary from my system, in /usr/bin/virsh, and not the
one that was just compiled. This is actually caused by a bug
in Makefile.am, where we didn't update the PATH to include tools.
While here, I also updated all of the scripts to properly define
the srcdir, abs_top_srcdir, and abs_top_builddir environment
variables. This is required if you want to be able to run the
tests standalone (i.e. ./test instead of from make check). I've
tested this on both RHEL-5 and Fedora-10 machines, and make check
works on both, as does running the individual tests by hand.

Otherwise logrotate barfs:

* qemud/Makefile.am: always create /var/log/libvirt/{lxc,uml} when
installing the logrotate conf; not ideal, but easier than making
the logrotate conf depend on which drivers are enabled
The devhelp/ directory files depend on libvirt-api.xml being
uptodate, but automake always processes SUBDIRS before the
current directory. So devhelp would be built and then the
libvirt-api.xml re-build, invalidating the devhelp data again.
To fix this all the rules for devhelp are moved directly
into the docs/Makefile.am allowing make to see the global
dependancy chain and thus build things in the correct order
* docs/Makefile.am: Add rules for devhelp rebuild
* docs/devhelp/Makefile.am: Remove devhelp rebuild
* configure.in: Remove docs/devhelp/Makefile.am
Add virNodeDeviceParseFile, and make virNodeDeviceParseNode non-static. These

A mistake in the generator was causing virInterface methods to be generated
with unpredicatable names ('ceUndefine', instead of just 'undefine'). This

The API docs explictly warn that we shouldn't use the C vir*GetConnect calls

FastParser uses sgmlop, a non-standard python module meant as a replacement
