Yes packages in RDO or any other way of implementing the service

2014-03-20 00:24:02 -0500 asked a question LBaas, How do we assign floating IP to the VIP

I have two nodes added to load balancer with private IPs and add vip with an IP from the private tenant IP range. I am ble to load balance the traffic. Now I want to make this public and assign a floating IP. What is the method for doing that? I tried to create VIP with external floating IP so that it can be resolved from outside but it does not work and had to revert the changes.

2014-03-20 00:18:54 -0500 answered a question LBaaS where is it running

You run command neutron agent-list, it will tell where it is running. If you have seperate neutron network node, then you have to run it on the network node along with other agents for l3, metadata, etc.

2014-03-20 00:15:09 -0500 asked a question nova compute instances -domain suffix issue

What is the method for appending dns suffix for each instance in the tenant network?

I know by adding the dhcp_domain=dev.sc2012lab.com in the nova.conf, we can do it across tenants. But this entry makes it default across all the tenants. Is there any way of doing it for per tenant basis, each tenant having separate dns suffix appended for instances as per the requirement?

2014-03-20 00:01:55 -0500 answered a question Openstack DNSaaS options for Havana

What is the mechanism used for registering guest instances in the DNS server from private tenant network? We create Guest Instances using heat templates and assign floating IPs on creation. The primary DNS mentioned in the tenant Subnet is the our standard DNS server used in the environment. The Windows VMs are able to join AD domain with information passed in user data for cloud-init and are discoverable using monitoring tool. But we are facing issues with Linux VMs. Linux VMs are not able register in DNS. Is there any workaround for linux machines to register with DNS?

The only was I was able to conclude was implement DNSaas and call its API using Heat template for registering with floating IP in DNS.

2014-03-14 03:10:53 -0500 asked a question Openstack DNSaaS options for Havana

Are there any options for implementing the DNSaaS for Havana release for RDO implementation? What are the integration methods available with existing nova-neutron setup?

The issue was with NFS storage mount for compute nodes. There were backups scheduled for the particular time resulting in issues with IOPs.

2014-03-04 06:57:12 -0500 answered a question metadata agent throwing AttributeError: 'HTTPClient' object has no attribute 'auth_tenant_id' with latest release

Following solution worked for us.

Edit the following file on neutron node running neutron-metadata-agent

/usr/lib/python2.6/site-packages/neutronclient/client.py

Go to roughly line 113 in the file and find the below statement:

    self.auth_token = token

And insert the following lines below it:

    self.auth_tenant_id = None
    self.auth_user_id = None

Restart the neutron-metadata-agent service
