Bandwidth monthly transfer

I plan to run 6 nodes for VPS Provisioning and Local LAN. Is it possible to restrict a user to vmbr0 and they have no way to create VM's or CT's on vmbr1 - vmbr5?

I don't think it's possible for now.
you can make a request on proxmox bugzilla :)
 
The main trick is to manage accounting outside of proxmox, as stats reset on every VM restart on proxmox side, so you can't really depend on it, by following this i managed to get Monthly Bandwidth Limitation working successfully through WHMCS product plans, with both auto suspend once limit is reached and auto unsuspend on limit reset every month or when client buy more bandwidth and it doesn't really get affected by VM restarts, Of course for automation to work you need to have WHMCS Daily cron Job running, didn't really want to have a separate cron for that, even though it is possible.
