libvirt users - Jul 2015 - libvirt-1.2.17 I can't define lxc container

Hello!

I'd like to set up my first lxc container using libvirt. I'd like to
start using the simplest configuration and next add things I need. So
I've got xml as below:
 <domain type='lxc'>
   <name>vm1</name>
   <memory>32768</memory>
   <os>
 <type>exe</type>
 <init>/init</init>
   </os>
   <vcpu>1</vcpu>
   <clock offset='utc'/>
   <on_poweroff>destroy</on_poweroff>
   <on_reboot>restart</on_reboot>
   <on_crash>destroy</on_crash>
 <features>
   <capabilities policy='on'>
   </capabilities>
 </features>
   <devices>
 <emulator>/usr/libexec/libvirt_lxc</emulator>
 <filesystem type='mount'>
   <source dir='/opt/vm-1-root'/>
   <target dir='/'/>
 </filesystem>
 <interface type='network'>
   <source network='default'/>
 </interface>
 <console type='pty' />
   </devices>
 </domain>

When I try to define container I'm getting:
virsh # define /tmp/vm1.xml
error: Failed to define domain from /tmp/vm1.xml
error: invalid argument: could not find capabilities for ostype=exe
domaintype=lxc


I can't also find similar problem using web search engine. Maybe someone
here can give me advice?

Marcin

Are you sure virsh has connected to the LXC driver - most likely
you have connected to QEMU. Try virsh -c lxc:/// or set the
LIBVIRT_DEFAULT_URI=lxc:/// environment variable

Ha! You are absolutly right. I thought that launching virsh I can manage
all types of VM managed by virsh.
Thank you!
