Yes, it's clear.
I read this paragraph, but I failed several times and don't know the exact 
reason, 
thus I have to check whether I'm on the steady ground.

/etc/xen/xmexample.hvm-dm has the line below:
vif = [ '', 'type=ioemu, bridge=xenbr0' ]
And I would like to know whether you booted successfully with such 
configuration,
I've never succeedded until I change the vif configuration to the simple one:
vif = [ '', 'ip=127.0.0.1, mac=aa:00:00:12:23:34' ]
(and the corresponding vif line in hvmconfig is changed as well.)

Do you encounter such a problem?

Merci.
