Hi Adam,
Yes get rid of NM – it will cause you nothing but headaches.

Is it worth uninstalling NetworkManager?
Thanks

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.

Adam,
Yes ;)
Sorry for my misunderstanding, i saw that when i check on my own KVM
configuration.
Do you have any log from KVM agent cloudstack or MGMT ?

Objet : New to Cloudstack - Issues going in to production - Public and
Guest bridges not up KVM
Hello
I have managed to test Cloudstack in the Lab with very little issues,
but now going into production (adding Loadbalanced Cloudstack management
servers and LACP nic bonding) I am having a few issues.
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?
Kind Regards
Adam Witwicki
