Proxmox 3.4 IPv6 problems

[Roman234]

Hello

I am trying to configure IPv6 on host system, but always receiving "Destination unreachable: Address unreachable"
Please check my configs maybe i something missed.

/etc/network/interfaces

Proxmox does not support IPV6 this time, unhappily. But you activate it for the webinterface: http://forum.proxmox.com/archive/index.php/t-19006.html
But DNS resolv from the webinterface, for example to an NFS server does not work, the only way is to mount in FSTAB with IPV6 and then bind as folder. ;(

What is your ultimate goal though? While with 3.4 the PVE interfaces don't support ipv6 (aside from all the other packages like rpcbind, a bunch of perl libs, parts of the kernel even (multicast issues etc.)), these are package specific issues. But general networking should work nonetheless as much as debian at that version supports it.
Meaning if you manually configure your network interfaces (and if you use the firewall, then also your ip6tables) on the host and guest systems correctly, most things should work as expected.

Could you describe your situation a bit more?
Which machines are part of the ipv6 network, host/guest/LAN/VLAN?
Where from and where to are you trying to connect when you receive the «destination unreachable» error message?
What does your ip6 routing table look like, (and the vlan10 table).
Do you have any ip6tables rules, and what are they (and if they're empty, what are the chain's policies (DROP/ACCEPT)?)
