Hi
In your techniques, you've told to ping the VM, but I don't get IP
at that point.
I want to wait, to get the ip from my VM. When i run a vm in
AWS(public cloud) cloud, I can wait for
/vm_hash['VM']['TEMPLATE'].has_key?('AWS_IP_ADDRESS')/, to get the ip.
In the above case, the key /AWS_IP_ADDRESS /seems to be depends on
AWS cloud.
If i create a vm in private cloud, for which key(like
/AWS_IP_ADDRESS)/ , i can wait to get the ip address?

As we would loose a 12 hr. window, I queued up a request in the dev
mailing list.
See if these options help you.

Hi
As mentioned in yout email you are looking for the AWS_IP_ADDRESS key,
which is only valid for Amazon Hybrid VMs. This value is obtained
through the monitorization process as reported/updated by Amazon.
In general, as boot time of a VM depends on the software stack running
wihtin, you cannot rely on the VM status reported by the hypervisors,
i.e. RUNNING means that the VM is running at hypervisor level but it
can be stuck in the virtual BIOS because of an error or misconfiguration.
In our internal testing platform we use two techniques:
1.- Pro-active ping the VM, a simple ping+sleep loop with a timeout.
2.- Make the VM callback home to a known URL (you may use onegate for
this)
Note that both requires connectivity to some extent between the knife
controller and the VM.
Cheers
Ruben

Dear Dev-OpenNebula,
When working on the addon-knife, upon launching a VM using the
OpenNebula API, there is a need to wait till the VM is fully
launched. Currently we wait until an IP address is available from
the VMPool.
Please find the reference of the code here.
https://github.com/OpenNebula/addon-knife/blob/master/lib/chef/knife/opennebula_server_create.rb#L168
We need a better way as OpenNebula can run in private clouds as well.
How can we know that a VM is fully launched and running ? What
parameter (status etc..) helps us to figure out that the VM is
running.
