Verifying SUSE OpenStack Cloud deployment

This document (7018756) is provided subject to the disclaimer at the end of this document.

Environment

SUSE OpenStack Cloud 6

Situation

After deploying all barclamps administrator needs a way how to verify that deployment is working and that it can start instances.

Resolution

There are multiple ways how to confirm that the deployment is working. One of the simplest and most widely used methods is to start an instance.

Before starting an instance an image must be uploaded. First user credentials must be sourced:

root@d52-54-00-40-d3-42:~ # . .openrc

Then basic image can be downloaded from the internet and uploaded using 'glance' client:

root@d52-54-00-40-d3-42:~ # wget http://download.cirros-cloud.net/0.3.5/cirros-0.3.5-x86_64-disk.img

root@d52-54-00-40-d3-42:~ # glance image-create --name cirros --visibility=public --container-format=bare --disk-format=qcow2 < cirros-0.3.5-x86_64-disk.img

After instance status became "ACTIVE" we can log in through the Horizon console or using ssh in a namespace and ping outside. Based on your configuration adding security rules may be required.

Additional Information

When testing SUSE OpenStack with integrated VMware, cirros image will not work since it is built for kvm based compute nodes. There is a special vmdk image provided by VMware suitable for testing installation:

root@d52-54-00-40-d3-42:~ # wget "http://partnerweb.vmware.com/programs/vmdkimage/trend-tinyvm1-flat-;ide;.vmdk"

Note the vmware_adaptertype is set to "ide"

root@d52-54-00-40-d3-42:~ # glance image-create --name trend-thin --is-public=True --container-format=bare --disk-format=vmdk --property vmware_adaptertype="ide" < "trend-tinyvm1-flat-;ide;.vmdk
