I've been wanting to give a try to libvirt to handle containers from LXC as well, but seems like if I follow the default configuration example, I get this:

virsh # create /etc/libvirt/lxc/axant.xml errore: Impossibile creare il dominio da /etc/libvirt/lxc/axant.xml errore: unknown OS type exe

[sorry for the Italian message, but it doesn't really matter]

The configuration is this:

<domain type='lxc'> <name>axant</name> <memory>14680064</memory> <os> <type>exe</type> <init>/init</init> </os> <vcpu>8</vcpu> <clock offset="utc" /> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>destroy</on_crash> <devices> <emulator>/usr/libexec/libvirt_lxc</emulator>

<filesystem type='mount'> <source dir='/media/chroots/axant'/> <target dir='/'/> </filesystem>

<interface type='bridge'> <mac address="8e:8b:e5:aa:28:b6" /> <source bridge="br0" /> </interface> <console type='pty' /> </devices> </domain>

am I doing something wrong or the doc at [1] is outdated somehow?

What is the output of 'virsh --connect lxc:/// capabilities'? Mine looks like: <capabilities> <host> <cpu> <arch>x86_64</arch> </cpu> <topology> <cells num='1'> <cell id='0'> <cpus num='2'> <cpu id='0'/> <cpu id='1'/> </cpus> </cell> </cells> </topology> </host> <guest> <os_type>exe</os_type> <arch name='x86_64'> <wordsize>32</wordsize> <emulator>/usr/libexec/libvirt_lxc</emulator> <domain type='lxc'> </domain> </arch> </guest> </capabilities> And I can define your posted config without error. If you don't have a guest block, defining any guest will fail, so the lxc capability detection probably needs to be taught how to work with your system.
