2015-02-26 03:07:02 -0600 asked a question DHCP reusing IPs

Hi Guys

I have set an environment with a neutron DHCP agent giving IPs to 2 different subnets. After the DHCP gave 5 instances the ips x.x.x.4 - 8 I wanted to delete some of those VMs and reuse their IPs on newly created instances, but the DHCP server just kept on going from x.x.x.9 to x.x.x.13.

I have changed the dhcp_lease_duration in the dhcp_agent.ini from 24H to 120S and I can see it's changed in the dnsmasq processes, but still no change in the leases.

After looking at the ipavailabilityranges table in the neutron database I see that the first IP he will assign new instances from is x.x.x.14, meaning he's not allocating any of the deleted IPs.

Is there anyway to make the DHCP use deleted IPs?!

I'm just thinking what will happen once I'll reach 254 created instances...

2014-10-22 04:44:53 -0600 answered a question Openstack Nuetron and VMware Standard Switches

Neutron cannot operate using Vmware's standard or distributed switches.

When implementing Vmware with OpenStack you can choose 2 possible networking ways:

  • Use nova network, which is not recommended for Production use.
  • Use Neutron with the VMware NSX plugin.

The Neutron plugin must be compatible with Nova hypervisor chosen.

2014-10-22 03:41:06 -0600 answered a question vmware datastore backend for images

Solved! Even though it wasn't a real problem...:) The progress can be seen through the controller server where Glance is installed on. Glance is firstly uploading the image to the /tmp folder in glance's server, and then uploads it to the glance backend(in my case a vmware datastore). Also, because my glance server had only 20GB of storage space, the upload failed because the image is 40GB. If any of the Openstack developers sees this, I think this is kind of a bug that the upload doesn't go straight to the backend...

2014-10-20 10:47:58 -0600 asked a question Adding vmware datastores with Cinder

I have an environment with a vSphere 5.5 cluster managed under Nova, I want to add some storage space by adding more datastores to the cluster. As far as I know, I can only create volumes and attach them to instances, so does anybody know if I can create new datastores with Cinder? It will probably have to use a different driver then VMDK, but I just want to know if it's possible.

2014-08-25 10:36:56 -0600 asked a question vmware glance 400 Bad request

Hi everyone,

I’m having a problem during my image upload I get a HTTP 400 error: “400 Bad Request” “Client disconnected before sending all data to backend” When looking at the logs I see: “File "/usr/lib/python2.7/site-packages/eventlet/", line 295, in send” “total_sent += fd.send(data[total_sent:], flags)” “error: [Errno 32] Broken pipe”

It seems that the session with vSphere works good, but for some reason it doesn’t send any data. Can anyone please assist?

I have a openstack all-in-one on RHEL 7. I configured my glance-api.conf file to use a datastore from my vcenter as a backend for images. I restarted the glance-api service and it came up good with no errors, so I uploaded the image through the horizon dashboard, the image is a flat-VMDK of 2008R2 template. My questions are: 1) Where can I see the progress through the CLI of the openstack node of the uploading process? 2) Why can't I see the image being uploaded to the datastore via the vsphere client?

Thanks in advance!
