I manually installed OVS version 2.0.2 and 2.1.0 and ran the
ovsdb-server in debugging mode. It did not give me any message in gdb
about the crash. The error log of /var/log/ovsopenvswitch-agent.log
showed the same error in 2 mins now. But the ovs-vsctl show command
showed:
ac789883-2266-453d-aef4-1d2682b44e7f
Bridge br-int
Port br-int
Interface br-int
type: internal
ovs_version: "2.1.0"
The ovs-ofctl show br-int showed:
OFPT_FEATURES_REPLY (xid=0x2): dpid:0000cec93765b24b
n_tables:254, n_buffers:256

That is the ovs-* commands are working even though I get this log. But
instantiating a new VM fauls with this msg in the nova-scheduler log.
File "/usr/lib/python2.7/dist-packages/nova/network/linux_net.py", line

The other server is compute node (OS ubuntu server 14.04)
I am able to create instance and assign a floating IP to the VM
which I
can ping and ssh. But I cannot access internet from the VM.
check the security group rules once .your floating ip should be a
public ip
.

This may be because your ovsdb-server is getting killed . you can
track the
route cause of that .
