HE IPv6 tunnel dividing /48 to /64's on Proxmox

elgs

I'm playing with Hurricane Electric's IPv6 tunnelbroker and am running Proxmox with a hardware node and multiple vms. Now I managed to allocate IPv6 addresses from my /64 pool to the vms. Here is how I did it:

On Hardware Node:

auto he-ipv6
iface he-ipv6 inet6 v4tunnel
       address 2001:xxxx:xxxx:xxxx::2
       netmask 64
       endpoint endpoint_ipv4
       local local_ipv4
       ttl 255
       gateway 2001:xxxx:xxxx:xxxx::1

iface vmbr0 inet6 static
       address 2001:xxxx:xxxy:xxxx::1
       netmask 64
       gateway 2001:xxxx:xxxx:xxxx::2

On VM:

iface eth0 inet6 static
    address 2001:xxxx:xxxy:xxxx::2
    netmask 64
    gateway 2001:xxxx:xxxy:xxxx::1

I also requested a /48 for my tunnel. Now if I want to allocate a /64 to each of the vm from my /48 block, should I create a bridge on the hardware node for each /64?

Maybe I should move this question to the Proxmox community. The thing I'm unsure is that whether it is necessary to modify the host node bridges every time a new /64 is handout from the /48 block. If this is the case, it makes it less practical in production. Please forgive my terribly poor network knowledge.
