"So to have one network that can caryies two different vlan's, the tag
should be set on ACS level."

Yes, I guess this is the only way (if one 1 logical Public
Network/bonds/whatever) - inside ACS you need 2 IP ranges on different
vlans.

and Yes you should be fine, with no network issues.

Your setup will be similar to:

bond0-->cloudbrX (or whatever Xen label you used - I reference here how it
works for KVM)
use cloudbrX as Network Label in Public network.
create 2 ranges (vlan80 and vlan81) inside 1 Public network
ACS will create folowing vlan and bridge interfaces  on your Xen/KVM
- bond0.80 -->brbond0-80<--Pubic NICs joined to this bridge
- bond0.81 -->brbond0-81<--Pubic NICs joined to this bridge

NOTE: From my experience: make sure that the IP ranges used in these 2
public IP ranges - are NOT overlapping AT ALL - meaning, they must have
different range (of course) and also use different gateway etc - I have run
into problems when I was using 1/2 of a /24 network, and later wanted to
add the rest 1/2 IPs as 2nd IP range...

Best,
