The network configuration works fine fine with xen4.4. But the network
cannot connected after I compiled xen4.6, even after I removed xen4.4.
Is there anything wrong? I believe it's the problem of grub configuration.
But I can't figure out where it is. Besides, can two xen version exists
together on one host? I'm now regret in upgrading cause everything now
seems in fuzzy and sucks.
