Can not ssh/ping etc into a running instance on any additional compute node(s)

Asked by arturo lorenzo

Can not ssh/ping etc into a running instance on extra compute nodes. I can ssh/ping on instances running inside the cloud controller OK. I have a Cloud Controller (CC1) running all the services (including nova-compute) and another server (CN1) with only nova-compute. I can see the instance running on the CN1 OK but I can not access it.
My network create cmd was: nova-manage network create 10.0.0.0/24 1 16 and I am associating those private IPs with public IPs (instances) to allow access to the VMs from other subnets. I am using FlatDHCPManager.
CC1 has a br100 with address 10.0.0.1 and eth0 with my public address.
CN1 has a br100 with another public address.
They are in the same subnet.

Thanks!

If this is current trunk, you probably just need to set
--flat-interface=eth0
restart network and compute
run a new instance.

This will move your public ip onto the bridge and bridge br100 into eth0
