I have found that IPv6 does not seem function correctly for a VirtualBox
VM bridged to a wireless interface, even when the wireless interface is
working flawlessly for the host.
Are you in an IPv6 network? Do you have VirtualBox installed? Do you
normally communicate via wifi? If so, I'd greatly appreciate it if you
could try this and let me know how you go (off list is fine, I'll
summarise).
- install a VM, OS is irrelevant as long as it supports IPv6
- configure the VM network interface to be bridged to the host adapter
(wlan0 or similar)
- see whether you have fully functional IPv6 on the VM
My experience is that I get weird partial functionality. I see
autoconfigured addresses and so on, but no useful connectivity is
possible - no pings, nothing. Neighbor discovery does not complete. And
yes, I have checked that no firewalls or packet filters are in the way.
The current suspects are my access point (an ancient Netgear, but the
host works fine over wifi), the wifi driver in Linux (but the host works
fine over wifi), and the VirtualBox network drivers (though they work
fine when the VM is bridged to an ethernet adapter)...
I've now seen this on 10.10 and 12.04, with two different wifi drivers
and across two versions of VirtualBox.
Regards, K.

"On Linux hosts, functionality is limited when using wireless interfaces
for bridged networking. Currently, VirtualBox supports only IPv4 over
wireless. For other protocols such as IPv6 and IPX, you must choose a
wired interface."

I hate it when that happens :-) Thanks for the pointer.
I wonder when Oracle will get with the program and fix this? IPX might
not be a big priority, but IPv6?!?
Fascinating that router advertisements work just dandy, but other stuff
doesn't.
Thanks, K.

Karl,
I don't know if it will help you but you can try VMware and see if they
are a little more advanced as IPv6 actually should be the standard since
at least > 10 years. I must confess I also still work with IPv4 but
that's I am lazy and follow the majority.

Not sure if this help either, but I run VMWare Player (5.0.0 on newer
64bit machine & 3.1.5 on 32bit machine) on my laptops and miredo (Teredo
tunnel) works w/o issue.
Host(s): Ubuntu 12.04 and also Win7
Guest(s): Ubuntu 12.04, Fedora 17, WinXP
Network: Wifi on the host
Bridge from guest to host - host is running wifi only.
$ ping6 ipv6.google.com
