I run IPv6 extensively and I'm personally a member of the North America v6 Task Force (NAv6TF). I have no problem running IPv6 in a VE but you have to use the veth device (I know people are going to jump up right now proclaiming that's not true - BUT IT IS). AFAICT, the vnet devices are NOT IPv6 compliant. They do not properly support MAC addresses and, consequently, link local addresses and can not play nice with neighbor discovery or router advertisements, router discovery, or auto-conf. For the same reason, I seriously DOUBT they play nice with the mandatory multicast addresses (all nodes, routers, etc, etc). I gave up totally on vnet ages ago for that very exact reason. I've never tested it but I seriously doubt the vnet device driver would pass any of the compliance test suites for that very reason. Avoid it like the plague as switch to veth with bridging and you'll be fine. > my vzctl version is ... > > vzctl version 3.0.22 > > Cheers, > > Matt. Regards, Mike -- Michael H.
