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.
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.

Abhishek

Hi Abhishek,
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?

Hi,
But this link talks about only resizing in single node. I was talking about VM migration in single node ?
So how does this relates to VM migration ?

I learn something (lots actually) every day.On Tue, May 26, 2015 at 10:19 AM, Kris G. Lindgren <[email protected]> wrote:I belive this can be possible by setting the allow_resize_same_host. More details can be found here: http://www.madorn.com/resize-on-single-compute.html . 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.

No. Providing a mechanism for this is discussed from time to time, but it is not currently available.
