2017-01-19 06:28:10 -0500 回答问题 Other interfaces not getting IP address

You can try 'userdata' option of nova create along with cloud-config file to configure the second and third interface on boot.

http://cloudinit.readthedocs.io/en/la...

Also all the interfaces will be named eth* as they are VMs.

Another option is to create a new image from the already configured instance (with 3 interfaces) and use it for future instances.

If I understand correct, your tenant machines are not able to reach the tenant router / gateway running in Controller node(s).

What kind of tunnel setup between Controller and Compute nodes? More information about your Neutron setup will be helpful.

2017-01-19 05:56:32 -0500 回答问题 Add keypair to running vm

Yes. You have to use manual steps to add keypair to a running VM.

Cloud-init supports injecting keypair during the creation creation (ie) first boot of the instance only.

2016-01-20 22:43:36 -0500 问了问题 volume & snapshot quota

I have Openstack setup based on Juno. Trying to understand how volume & snapshot quota are calculated.

Cinder volume is based on LVM.

Volume is of 60GB and a snapshot created from it also 60GB (ie) total quota consumed is 120GB.

Is this how quota is calculated? is it not 60 GB + snapshot delta size?

2016-01-20 04:04:38 -0500 问了问题 Creating LVM cinder volume from snapshot takes time

When we try to create a new volume from snapshot (LVM based cinder), it is taking time to complete and fills 100%. Is it the expected behaviour.

volume-7252176c-dece-46b0-90ee-df6029cfa747    cinder-volumes Vwi-a-tz-  60.00g cinder-volumes-pool                                             100.00

Any suggestion to make it faster?

2016-01-03 07:58:07 -0500 评论回答 separate tenant public endpoint

Have created another question stating my use case Https://ask.openstack.org/en/question...

2016-01-03 07:56:50 -0500 问了问题 change public api url

I have a private cloud Openstack setup (kilo) behind firewall. I got a requirement to access Openstack from Internet using its APIs. To enable accrss from Internet, created a ptoxy server in DMZ that forwards requests to Openstack behind firewall.

When 'keystone endpoint-list' equivalent is used from Internet, it provides public URL which in side the firewall. Can I change the public URL IP to that of DMZ server? How to change? Will it beak anything?

I am using Horizon UI in internal network.

2015-12-14 10:48:33 -0500 问了问题 First boot on ISO and subsequent boot on Volume

We have a setup in VMWare as follows:

  • Boot a blank VM with ISO image (presented as CDROM)
  • The ISO image connects to a server (say Server A) and registers in it
  • Once registered, the Server A installs a bootable software in the blank disk of the VM
  • Detach the CDROM from the VM
  • As part of the installation the software from Server A does multiple reboot of the VM and finishes its installation

We are trying to setup the same on Openstack instance

  • Boot/Create a new instance from ISO image with a volume attached to it
  • The IOS image connects and registers in Server A
  • The software in the third server installs a bootable software in the volume attached to the instance
  • Detach the ISO Image -----> unable to detach struck here

All the above steps are controlled by Orchestration tool. When instance reboots it always boots from ISO image since unable to detach and thus the process doesn't complete.

In other words, only the first boot should boot from ISO image and the next reboots are thru volume.

Any suggestion to simulate the VMWare steps in Openstack instance.
