IPv6 routing question

I have built a xen infrastructure that can handle both IPv4 and IPv6 traffic. I have connected my 3560(under vlan) to the xen machine(Linux). IPv4 works fine under host and vm. But IPv6 works only under host, not inside vm. The requirement setting inside host machine(Linux) already correct. But still IPv6 on vm doesn't work. I am wondering if this is issue with my 3560 settings. The prefix I got from provider is 2001:B031:208:FF00::/64.

#sh ipv6 interface

Vlan2 is up, line protocol is up

  IPv6 is enabled, link-local address is FE80::6FE:7FFF:FEFE:EA41

  No Virtual link-local address(es):

  No global unicast address is configured

  Joined group address(es):

    FF02::1

    FF02::2

    FF02::1:FFFE:EA41

  MTU is 1500 bytes

  ICMP error messages limited to one every 100 milliseconds

  ICMP redirects are enabled

  ICMP unreachables are sent

  Output features: Check hwidb

  ND DAD is enabled, number of DAD attempts: 1

  ND reachable time is 30000 milliseconds (using 30000)

  Default router is FE80::230:88FF:FE20:5335 on Vlan2

#sh ipv6 routers

Router FE80::230:88FF:FE20:5335 on Vlan2, last update 1 min

  Hops 64, Lifetime 1800 sec, AddrFlag=0, OtherFlag=0, MTU=1500

  HomeAgentFlag=0, Preference=Medium

  Reachable time 0 (unspecified), Retransmit time 0 (unspecified)

  Prefix 2001:B031:208:FF00::FFFF/64

    Valid lifetime 2592000, preferred lifetime 604800

Router FE80::225:90FF:FEAC:ED04 on Vlan2, last update 2 min

  Hops 64, Lifetime 1800 sec, AddrFlag=0, OtherFlag=0

  HomeAgentFlag=0, Preference=Medium

  Reachable time 0 (unspecified), Retransmit time 0 (unspecified)

  Prefix 2001:B031:208:FF00::/64 onlink autoconfig

    Valid lifetime 86400, preferred lifetime 14400

Thanks in advanced.
