I need to support IPv6, and am playing with Unbuntu as a VE. I've used it as itself naturally, and IPv6 wasn't a problem to configure. My other VEs (not debian based: centos, fedora, trixbox) configure and use IPv6 happily (yay!).
I'm able to configure the IP with vzctl, and once the VE is up and entered, /etc/network/interfaces has an IPv6 config (IP changed for posterity):
iface venet0 inet6 static
address ::1
netmask 128
up ifconfig venet0 add a:b:c::d
However ifconfig output shows nothing configured:
venet0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00
inet addr:127.0.0.1 P-t-P:127.0.0.1 Bcast:0.0.0.0 Mask:255.255.255.255
UP BROADCAST POINTOPOINT RUNNING NOARP MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)
I'm looking for this to come up correctly when the VE is started (like the other VEs), and am wondering if the syntax isn't generated correctly or if I'm overlooking something. I don't have access to a non-virutalized ubuntu box to muck with, or spare equipment to blast it onto (zomg, a reason for virtualization!!1!1).
And searching for IPv6 + (any distro) results in "omg what the hell is ipv6, and how do I get rid of it because it takes me an extra 30 seconds for dns lookups to time out because it found a AAAA record and my computer/ISP isn't cool enough to have tunneled/native IPv6 connectivity" posts.

Hi,
can you please post some information, too:
* distr. of your hardware node
* is IPv6 enabled in /etc/vz/vz.conf ?
* what vzctl version and which version of ve os template is used ?
|
Distro used for "HN" is CentOS 5.1
Yes, IPv6 is enabled in vz.conf (otherwise my other VE's wouldn't have working IPv6 connectivity  )
vzctl version 3.0.18
I grabbed the unbuntu 7.10 precreated template cache: ubuntu-7.10-i386-minimal
http://openvz-mirror1.rapidvps.com/template/precreated/ubunt u-7.10-i386-minimal.tar.gz
Again, the other VEs I'm running, which are essentially RedHat based (centos, fedora) have 100% native IPv6 connectivity using the same command that isn't working for the ubuntu VE:
vzctl set VEID --ipadd x.x.x.x --save
vzctl set VEID --ipadd a:b:c::d --save
(where x.x.x.x is a real ipv4 address and a:b:c::d is a real ipv6 address)

I've been scouring forums, and saw the mention of vzctl needing to be 3.0.19 for ubuntu to "work". I've had no problems with it working with 3.0.18, including IPv4 networking, but I'm grabbing a copy of 3.0.22 and will update if that fixed my issue of IPv6 not working.
{EDIT}
No luck. It took a moment when applying the IP addresses, fired up the VE, and after logging in, exact same /etc/network/interfaces configuration and output from ifconfig showing no inet6 address configured on venet0

Can you try to do this with some Debian template?
|
As requested, I used debian-4.0-i386-minimal
Different valid IPs both v4/v6 from the Ubuntu VE
Survey says...........working!
/etc/network/interfaces is line for line (excluding the IPs), exactly the same in both debian-4 and ubuntu-7.10, just that debian-4 works.

6 hours later, and a nap.....
I grabbed the ubuntu-6.06-i386-minimal template from contrib, created a whole new VE, and after launching:
- didn't have IPv6 configured on venet0
- venet0:0 wasn't created with the IPv4 IP either
So I ran: /etc/init.d/network restart
got the following output:
* Reconfiguring network interfaces...
SIOCSIFADDR: File exists
Failed to bring up venet0.
[ ok ]
And despite errors:
- venet0 had the IPv6 address
- venet0:0 was created with the IPv4 address
- I have working IPv4/6 connectivity
So I tried the ubuntu-7.10-i386-minimal template also out of contrib, but it has the same behavior as the other 7.10 template I've been trying.

I went through the wiki steps for installing under a Debian environment and then rolling your own Gutsy template (which are awesome resources, thanks to those that wrote them up):
http://wiki.openvz.org/Installation_on_Debian
http://wiki.openvz.org/Ubuntu_Gutsy_template_creation
After creating a brand new VE based on an installation of Ubuntu-7.10-server-i386, still no IPv6 love under the VE.
Of course on that brand new 7.10 server I installed, IPv6 works without issue.
So I suppose I could try 7.0.4-server-i386 since I just found the cd in my stack, and see if its an issue with the 7.x branch seeing as Debian-4.0 and Ubuntu-6.0.6 both supported IPv6 as a VE.
{EDIT}
No luck with Ubuntu-7.0.4-server-i386 (feisty) either. And I had even tried /etc/init.d/network restart in all my attempts
