# What this daemon does:
|

# 1. Configure public networks dynamically on startup (e.g. bonding, vlans, etc.) from config
|
||||
# * no /etc/network/interfaces config for these - just mgmt interface via DHCP!
|
||||
# 2. Watch ZK /networks
|
||||
# 3. Provision required network interfaces when a network is added
|
||||
# a. create vxlan interface targeting local dev from config
|
||||
# b. create bridge interface
|
||||
# c. add vxlan to bridge
|
||||
# d. set interfaces up
|
||||
# e. add corosync config for virtual gateway IP
|
||||
# 4. Remove network interfaces when network disapears
