[one-users] something more sophisticated ...

[Ulrich Schwickerath]

Hi, all,

I have a dummy user question for an a bit more sophisticated use case.
Let's say I have 2 networks A and B with fixed IP/MACs, and I have 2 
user groups G1 and G2. Now I want that users of G1 can only use IPs from 
network A (that's easy), and that users from group B can use leases from 
network B _first_ and overflow to A if B is full or all machines are 
highly used. Is that possible ?

In reality I have another network C which must be exclusively used by 
another user group G3. This network belongs to a group G3, is owned by 
the only user in that group and has permission set so that only this 
user can use this network.

Now I naively tried not to specify the network I want to use in the VM 
template, so my NIC definition is simply:
#------ networking -----
NIC = [
         MODEL="virtio"
       ]
Being a user of group G2 I thought I would get a MAC from B but I got 
one from network C. Is that a bug or did I miss something ?

Thanks for your help!
Ulrich
