functionality of libvirtd, rather than to pull in all subpackages.
The problem with VLAN is that the user still has to manually create the
vlan interface on the host. Then the generated configuration will use
it as a nerwork hostdev device. So the generated configurations of the
following two fragments are equivalent (see rhbz#1059637).
LXC from native: migrate veth network configuration
Some of the LXC configuration properties aren't migrated since they
would only cause problems in libvirt-lxc:
* lxc.network.ipv[46]: LXC driver doesn't setup IP address of guests,
see rhbz#1059624
* lxc.network.name, see rhbz#1059630
If no network configuration is provided, LXC only provides the loopback
interface. To match this, we need to use the privnet feature. LXC will
also define a 'none' network type in its 1.0.0 version that fits
libvirt LXC driver's default.
LXC rootfs can be either a directory or a block device or an image
file. The first two types have been implemented, but the image file is
still to be done since LXC auto-guesses the file format at mount time
and the LXC driver doesn't support the 'auto' format.
LXC driver: started implementing connectDomainXMLFromNative
This function aims at converting LXC configuration into a libvirt
domain XML description to help users migrate from LXC to libvirt.
Here is an example of how the lxc configuration works:
virsh -c lxc:/// domxml-from-native lxc-tools /var/lib/lxc/migrate_test/config
It is possible that some parts couldn't be properly mapped into a
domain XML fragment, so users should carefully review the result
before creating the domain.
fstab files in lxc.mount lines will need to be merged into the
configuration file as lxc.mount.entry.
As we can't know the amount of memory of the host, we have to set a
default value for max_balloon that users will probably want to adjust.
virConf now honours a VIR_CONF_FLAG_LXC_FORMAT flag to handle LXC
configuration files. The differences are that property names can
contain '.' character and values are all strings without any bounding
quotes.
Provide a new virConfWalk function calling a handler on all non-comment
values. This function will be used by the LXC conversion code to loop
over LXC configuration lines.

event: server RPC protocol tweaks for domain lifecycle events
This patch adds some new RPC call numbers, but for ease of review,
they sit idle until a later patch adds the client counterpart to
drive the new RPCs. Also for ease of review, I limited this patch
to just the lifecycle event; although converting the remaining
15 domain events will be quite mechanical. On the server side,
we have to have a function per RPC call, largely with duplicated
bodies (the key difference being that we store in our callback
opaque pointer whether events should be fired with old or new
style); meanwhile, a single function can drive multiple RPC
messages. With a strategic choice of XDR struct layout, we can
make the event generation code for both styles fairly compact.
I debated about adding a tri-state witness variable per
connection (values 'unknown', 'legacy', 'modern'). It would start
as 'unknown', move to 'legacy' if any RPC call is made to a legacy
event call, and move to 'modern' if the feature probe is made;
then the event code could issue an error if the witness state is
incorrect (a legacy RPC call while in 'modern', a modern RPC call
while in 'unknown' or 'legacy', and a feature probe while in
'legacy' or 'modern'). But while it might prevent odd behavior
caused by protocol fuzzing, I don't see that it would prevent
any security holes, so I considered it bloat.
Note that sticking @acl markers on the new RPCs generates unused
functions in access/viraccessapicheck.c, because there is no new
API call that needs to use the new checks; however, having a
