Hi Adam, As per Nicolas’ comments probably a good idea to increase the verbosity of your agent logs and see if anything pops up – also check your normal /var/log/messages.
My twopence worth apart from this: - Your config looks OK. - Have you made sure LACP is actually up and running on your switch stack? If LACP on KVM can’t handshake correctly with the switches I could see you having problems. - What does a “cat /proc/net/bonding/bond0” tell you when the bridge is down? - Overall I suspect this could also be down to NIC drivers – it may be an idea to make sure these are fully up to date. - If all else fails and you cannot find a resolution you could bodge a workaround with libvirt hooks – by putting a script to up all bridges into /etc/libvirt/hooks/network – see https://libvirt.org/hooks.html for more info. I would use this as your last option though.

Do you have any log from KVM agent cloudstack or MGMT ?

When starting my first instance the network bridges stay down 13: brbond0-999: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000 If I bring this up using ip link set dev brbond0-999 up the bridge comes up fine and the systemVMs work. Any ideas?
