What's /etc/resolv.conf look like in your UML? You have to specify a
name server here.
Does your FORWARD-chain allow udp 53 from 192.168.0.0/24 to the
 
    is this forward-chain of host ?  i don't know how to ? iptables -t FORWARD.... ,please give a practical command.

nameservers you have in /etc/resolv.conf?
 
yes the resolv.conf has the same nameserver . in host ,ping domain name ok, in uml ,it can't .
