I want to wait, to get the ip from my VM. When i run a vm in

In the above case, the key <i><big><span>AWS_IP_ADDRESS
</span></big></i>seems to be depends on AWS cloud.<br>
If i create a vm in private cloud, for which key(like <i><big><span>AWS_IP_ADDRESS)</span></big></i> , i can wait to
get the ip address?<br>

<div dir="ltr">Hi
<div><br>
</div>
<div>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.</div>
<div><br>
</div>
<div>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.</div>
<div><br>
</div>
<div>In our internal testing platform we use two techniques:</div>
<div><br>
</div>
<div>1.- Pro-active ping the VM, a simple ping+sleep loop with
a timeout.</div>
<div>2.- Make the VM callback home to a known URL (you may use
onegate for this)</div>
<div><br>
</div>
<div>Note that both requires connectivity to some extent
between the knife controller and the VM.</div>

Dev-OpenNebula,<br>
<br>
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.<br>
<br>
Please find the reference of the code here.<br>
<a href="https://github.com/OpenNebula/addon-knife/blob/master/lib/chef/knife/opennebula_server_create.rb#L168" target="_blank">https://github.com/OpenNebula/addon-knife/blob/master/lib/chef/knife/opennebula_server_create.rb#L168</a><br>
<br>
We need a better way as OpenNebula can run in private
clouds as well.<br>
<br>
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.<span><font color="#888888"><br>
