Hi Francisco,

here is our working config:

# This is the network config written by ansible

      interfaces:
      - eno1
      - enp137s0f0
      parameters:
        mode: balance-tlb
    # frontnet
    bond1:
      interfaces:
      - eno2
      - enp137s0f1
      parameters:
        lacp-rate: fast
        mode: 802.3ad
        transmit-hash-policy: layer3+4

    cloudbr0:
      interfaces: [bond0]
      addresses: [XXX/24]
      dhcp4: false
      dhcp6: false
      routes:
        - to: default
          via: XXX
      nameservers:
        addresses: [XXX]
      parameters:

Betreff: KVM bridges kill the network.

Good morning guys,

I have tried many ways to configure the two bridges required by cloudstack, and 
in all my attempts this config kills the network. I will post my configuration 
here, maybe you can help me guys. I have tried following cloudstack tutorials, 
I have tried with openswitch, and the same result.
Thank you all in advance
