a09bbc024d LXC from native: map vlan network type 
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.network.type = phys
lxc.network.link = eth0.5

lxc.network.type = vlan
lxc.network.link = eth0
lxc.network.vlan.id = 5

b73c029d83 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

7bfd6e97ec LXC from native: implement no network conversion 
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.

a41680f8c5 LXC from native: migrate fstab and lxc.mount.entry 
Tmpfs relative size and default 50% size values aren't supported as
we have no idea of the available memory at the conversion time.

197b13e5d9 LXC from native: import rootfs 
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.

7195c807b2 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.
