Open Stack

Hi, Bob,
Thanks for you feedback. But I still can not finish the installation after viewed the material you provided.
That README.md is same with the one in my previous mail.
the install-devstack-xen.sh seems new one so what I do today is based on this.
My Xenserver PC has two NIC, one is 10.8.x.x, the other is 10.11.x.x (but did not config this IP at xenserver side, set it in shell)
After install-devstack-xen.sh run, the devstackosdomu will display "Bad archive mirror" when "Choose a mirror of the Ubuntu archive "
What's the probably reason for this?

And please also confirm one thing: After all these was setup, can I use openstack webui to manage the VMs imported inside Xenserver?

Following is the shell I used for reference:
========================================
#!/bin/bash

# This script installs a DevStack DomU VM on
# the specified XenServer.
set -e

function syntax {
    echo "Syntax: $0 <private key> <host> <root password>"

    " \$XenServerPassword can be used as an alternative"
    exit 1
}

  Hi,

   

  That particular guide is out of date I'm afraid.  We have an action to update the guide fully, but I have made some interim edits to clarify the current situation.  The better news is that installing DevStack on a XenServer is now easier than when the guide was written.

   

  The README.md from devstack explains how to get it set up on a XenServer: https://github.com/openstack-dev/devstack/blob/master/tools/xen/README.md

   

  There is also a script which makes deployment fully automated at https://raw.github.com/citrix-openstack/qa/master/install-devstack-xen.sh. 

   

  In terms of the specific questions:

  1-3

  Use the new approach above which is significantly simpler and more automated, that should resolve the problems.

   

  4. The localrc config file on github is different with the one in video. Which is correct? Or it is environment depended?

  It is dependent upon the environment, in particular the network setup.  The all-in-one script above (install-devstack-xen.sh)  has some defaults in the localrc which work in many cases, but things like the IP addresses may need to be updated if they don't fit your existing environment.

   

  5. Is it feasible to use devstack with Suse OpenXen instead of Xenserver? any help document?

  You should be able to use devstack with this, yes.  Perhaps following http://devstack.org/guides/single-machine.html and making sure that you set the VIRT_DRIVER and any other settings that are needed for the Xen integration.

  Note that I haven't personally used devstack with the xen integration, so there may be issues - but I'm sure we can work through them.

   

  Bob

  Gents,

  Not sure if can get reply here for such installation issues.

  I want to install DevStack with XenServer (to verify some idea with Openstack on Xen hepervisor) and blocked by some problems.

   

  What I refer:

  https://github.com/openstack-dev/devstack/blob/master/tools/xen/README.md
  https://wiki.openstack.org/wiki/XenServer/DevStack
  And a video instruction on youtube.

   

  My issues are:

   

  1. there is step of build_xva.sh on github. but have on wiki and video.

  Is this step must?

  2. I tried build_xva.sh on a ubuntu machine installed xe and xm, but the script stopped at xe vm-list ....

  Is this my configuration issue? seems a low level error.

  3. Without build_xva, I direct use install_os_domU, but failed at start the VM. By switch to the ALLINONE vm, it stop at configuration screen.

  4. The localrc config file on github is different with the one in video. Which is correct? Or it is environment depended?

  5. Is it feasible to use devstack with Suse OpenXen instead of Xenserver? any help document?
