Hi
I am getting a strange network communication issue while connecting to the VM under opennebula cluster. I cannot get ping/any traffic from one of my private IP blocks to the public IP of OpenNebula VM. I am confident about the network routing issue and get all access to the same IP to another non-opennebula based cluster under the same network infrastructure.
The scenario is as below. I find there is no network or routing-related issues as the same IP works on different non-opennebula based cluster. I thought it may be an issue with the security group which was assigned to that network. To resolve this I have created a new “Security Group” allowing all its and protocol but no luck.
