RE: New to Cloudstack - Issues going in to production - Public and Guest bridges not up KVM


Hi Adam,


Your network bridge with KVM to be used with cloudstack need to be named like this  :  cloudbr0, cloudbr1


So you have to name your  bridge brbond0-999 -> clourbr1


Do you have only one bond ? (bond0)

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
