Thread: IPv6 unavaliable after idle

-

i have several ubuntu 12.04.2 64bit server vms running under xenserver 6.1.

whenever left ~30 mins no traffic on ipv6, network becomes unavailable, requiring restart of networking service bring up. ipv4 still active.

code:
:~# ping6 google.com connect: network unreachable
they able ping other vms running on same host os, nothing above host, though host , other vms have ipv6 access.

appreciated. wader

what kind of ipv6 using?

output of:

code:
mtr -nrc2 ipv6.google.com  dmesg | grep -i ipv6  ip -6 addr show
