These VIR_XXXX0 APIs make us confused, use the non-0-suffix APIs instead.
How do these coversions works? The magic is using the gcc extension of ##.
When __VA_ARGS__ is empty, "##" will swallow the "," in "fmt," to
avoid compile error.
example: origin after CPP
high_level_api("%d", a_int) low_level_api("%d", a_int)
high_level_api("a string") low_level_api("a string")
About 400 conversions.
8 special conversions:
VIR_XXXX0("") -> VIR_XXXX("msg") (avoid empty format) 2 conversions
VIR_XXXX0(string_literal_with_%) -> VIR_XXXX(%->%%) 0 conversions
VIR_XXXX0(non_string_literal) -> VIR_XXXX("%s", non_string_literal)
(for security) 6 conversions

Using the 'personality(2)' system call, we can make a container
on an x86_64 host appear to be i686. Likewise for most other
Linux 64bit arches.
* src/lxc/lxc_conf.c: Fill in 32bit capabilities for x86_64 hosts
* src/lxc/lxc_container.h, src/lxc/lxc_container.c: Add API to
check if an arch has a 32bit alternative
* src/lxc/lxc_controller.c: Set the process personality when
starting guest
Allow for a host UUID in the capabilities XML. Local drivers
will initialize this from the SMBIOS data. If a sanity check
shows SMBIOS uuid is invalid, allow an override from the
libvirtd.conf configuration file
* daemon/libvirtd.c, daemon/libvirtd.conf: Support a host_uuid
configuration option
* docs/schemas/capability.rng: Add optional host uuid field
* src/conf/capabilities.c, src/conf/capabilities.h: Include
host UUID in XML
* src/libvirt_private.syms: Export new uuid.h functions
* src/lxc/lxc_conf.c, src/qemu/qemu_driver.c,
src/uml/uml_conf.c: Set host UUID in capabilities
* src/util/uuid.c, src/util/uuid.h: Support for host UUIDs
* src/node_device/node_device_udev.c: Use the host UUID functions
* tests/confdata/libvirtd.conf, tests/confdata/libvirtd.out: Add
new host_uuid config option to test
* src/libvirt.c src/lxc/lxc_conf.c src/lxc/lxc_container.c
src/lxc/lxc_controller.c src/node_device/node_device_hal.c

src/util/logging.c src/xen/sexpr.c src/xen/xend_internal.c
src/xen/xm_internal.c: Steve Grubb <sgrubb@redhat.com> sent a code
review and those are the fixes correcting the problems
https://bugzilla.redhat.com/show_bug.cgi?id=528575
virsh -c lxc:/// autostart vm1
was crashing the daemon
* src/lxc/lxc_conf.h src/lxc/lxc_conf.c: initialize the driver
autostartDir to avoid a NULL reference and implement autostart for LXC
* 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.
