Open Stack

hi
    Currently, nova metadata service is proxy by metadata agent in dhcp agent or l3 router agent, it is depended on whether network attach to router or not. In essential, metadata agent implements a http proxy functionality by computer node host protocal stack. In other words, it exposes host protocol stack to vm. If vm is a attacker, it can launch a HTTP GET flood attacks. then it may affect this computer node. I would like to hear you guy's  opinion. any comment is welcome. thanks.
