The last libvirt support device hotplug,you can use it to add devices for
container on host.
Here is an example
cat device.xml
<hostdev mode='capabilities' type='misc'>
<source>
<char>/dev/fuse</char>
</source>
</hostdev>
You can use virsh cmd "attach-device domainname device.xml" to hot plug
this fuse device to the container.
You can add the xml into configure file too.
