<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Verdana",sans-serif">Hi Saju,<br>
<br>
It is on KVM. I had tried on setting up a multinode environment with a controller, network and 2 compute nodes. But I am facing issues in that. Actually, one of the compute's is able to boot a VM and the VM goes to Active state. While on the other when I try
to boot a VM it stay in scheduling state only. Also if I try to migrate the Active VM from 1 compute to other it gives me an error and the VM is left in error state.<br>
<br>
So I thought of trying it on single-node kilo openstack, where I noticed that we have only 1 compute host in single-node setups but then also the VM gets migrated. So my question was where does the VM gets migrated when we don't have another compute host.
<br>
<br>

Abhishek<br>

<p><span style="font-size:10.0pt;font-family:"Verdana",sans-serif">Hi Abhishek,<br>
Anyway, You are planning to work on VM migration. So it is better to setup multinode environment. Where is your single node setup ? Is it on KVM or Virtualbox VM?<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Verdana",sans-serif">Hi,<br>
<br>
But this link talks about only resizing in single node. I was talking about VM migration in single node ?<br>
<br>
So how does this relates to VM migration ?<br>

<p class="MsoNormal" style="margin-bottom:12.0pt"><span style="font-size:10.0pt;font-family:"Verdana",sans-serif">I belive this can be possible by setting the allow_resize_same_host. More details can be found here:
<a href="http://www.madorn.com/resize-on-single-compute.html" target="_blank">http://www.madorn.com/resize-on-single-compute.html</a> . I believe the issue Dave is talking about is specifically targeting the same host for resize assuming the host can support
it in a milti-node setup. As getting the scheduler to choose the current host in the multihost setup is 95 percent of the battle.<br>
