Hallo Community,
i have a "little" Problem with the new Debian Whezzy (Kernel:
3.9-0.bpo.1-amd64) and the IPv6 for the DomU`s.
The Dom0 is okay, IPv6 Adress is configure and the Ping (ping6 ipv6.google.com)
work:
PING ipv6.google.com(ham02s12-in-x13.1e100.net) 56 data bytes
64 bytes from ham02s12-in-x13.1e100.net: icmp_seq=1 ttl=56 time=10.5 ms
64 bytes from ham02s12-in-x13.1e100.net: icmp_seq=2 ttl=56 time=10.6 ms
64 bytes from ham02s12-in-x13.1e100.net: icmp_seq=3 ttl=56 time=10.5 ms
I create the DomU with IPv4 Adress and add the IPv6 later:
/etc/xen/test1.cfg
bootloader = '/usr/lib/xen-4.1/bin/pygrub'
vcpus = '1'
memory = '512'
root = '/dev/xvda2 ro'
disk = [
'phy:/dev/lvm/test1-disk,xvda2,w',
'phy:/dev/lvm/test1-swap,xvda1,w',
]
name = 'test1'
vif = [ 'ip=x.x.x.x
x:x:x:x::11,mac=00:16:3E:BF:1E:43,vifname=test1' ]
on_poweroff = 'destroy'
on_reboot = 'restart'
on_crash = 'restart'
When i am started the DomU, i become this message:
Error: Device 0 (vif) could not be connected. /etc/xen/scripts/vif-route failed;
error detected.
In the Syslog File is the output:

I read the instruction on the german site
(http://www.pug.org/mediawiki/index.php/IPV6/xen-route) and I test it, but the
DomU isn`t started (I changed the /etc/xen/scripts/vif-route).
Have any idea, where is problem?
Thank you for help.
Best regards
Ronny

See you the Problem? I am not.me neither, but then this log doesn''t seem to contain much "meat" i.e. it doesn''t appear like the script is actually doing anything. I expect it is really and we simply haven''t captured the right bits. You might want to test out my suggested exec runes in a test script, perhaps I got the syntax wrong. Or just add your own "echo foo > file" tests to the script to try and track it down that way. Ian.

me neither, but then this log doesn''t seem to contain much
"meat" i.e.
it doesn''t appear like the script is actually doing anything. I expect
it is really and we simply haven''t captured the right bits.
You might want to test out my suggested exec runes in a test script,
perhaps I got the syntax wrong.
Or just add your own "echo foo > file" tests to the script to try
and
track it down that way.
Ian.

Hi Ian,
sry for my late answer, i was sick the last days.
I change some files and the DomU started with ipv6:
nano /etc/xen/xend-config.sxp
Old:
(network-script ''network-route netdev=eth0'')
(vif-script ''vif-route netdev=eth0'')
New:
(network-script network-route)
(vif-script vif-route)
nano /etc/xen/scripts/vif-common.sh
Old:
ip_of()
{
ip addr show "$1" | awk "/^.*inet.*$1\$/{print \$2}" | sed
-n ''1 s,/.*,,p''
}
New:
ip_of()
{
ip -4 -o addr show primary dev $1 | awk ''$3 == "inet"
{print $4; exit}'' | sed ''s#/.*##''
}
But now, I can ping from the DomU to the Dom0 and not to the gateway or the the
internet. Do you have a tip how I can fix this?
Some entry I change in the file /etc/sysctl.conf:
net.ipv4.conf.all.rp_filter = 1
net.ipv4.icmp_echo_ignore_broadcasts = 1
net.ipv4.ip_forward = 1
net.ipv4.conf.eth0.proxy_arp = 1
net.ipv6.conf.all.forwarding = 1
net.ipv6.conf.all.proxy_ndp = 1
net.ipv4.conf.default.proxy_arp = 1
ipv4 is not a problem, this ist okay, but ipv6 not.
Traceroute:
traceroute to ipv6.google.com (2a00:1450:4005:808::1012), 30 hops max, 80 byte
packets
1 IPv6 Dom0 (IPv6 Dom0) 0.207 ms 0.149 ms 0.135 ms
2 IPv6 Dom0 (IPv6 Dom0) 2999.852 ms !H 2999.809 ms !H 2999.759 ms !H
Thank you very much

Do you have a tip how I can fix this?I'm afraid not, I've never setup a system with IPv6 and know very little about the specifics of how one would do so. You issues seem to be getting more into the realm of firewall/networking specific rather than issues with Xen as such. Perhaps someone else on the list has done this and can advise.
