Thanks for that update.

We will try that.

If you are using 4.10, we do support migrations when a VM is in

Next release (4.12) will include the ability to migrate in poweroff.


Meanwhile a work around, (there are two actually fake a hypervisor 
failure to get the VM in unknown and use the previous feature or fake 
a migration failure).


I've not tested this myself so watch out:

1.- Update the kvm migrate script by adding at the very beginning 
something like:


sleep 600
return

We want to get the VM in MIGRATE state for a while

2.- Manually move the VM: Go to the hypervisor, and shut it down (i.e. 
virsh...); move the config files (those in ssh system datastore); got 
to the other hypervisor and manually create the VM.


3.- use onevm recover vmid success, the VM should become running in 
the new host. (The sleep'ed migrate operation should be ignored as the 
VM would be RUNNING)


4.- Undo the changes in the migrate script.

Good Luck

HI,

Is there a way to move a VM from one host to an other when
migrate/live
migrate fails.

We are using ceph as backend and have ssh systemstore.

A process like
1 poweroff VM
2 Move the configs
3 -- I guess that we should do some manual db changes --
4 poweron machine on new host

Any comments would be great.

Thanks,
- Karsten

Re: [one-users] OpenNebula lost ip addressess.

[Daniel Dehennin]

Hello,

Leszek Master keks...@gmail.com writes:

 Today i've had lack of power, so long that my UPS batteries died, and so
 the servers. After rebooting everything i noticed that 0 of my VM's started
 automatically. So here's the first question, is there any way to manage
 autostart vm after infrastructure rebooting?

For information, there is an opened issue for this: #1290[1].

 The second thing is that when i started my vm's the ip addresses got messed
 up. How can it happen ? How to secure my infrastructure from changing ip
 addressed?

I'll let the OpenNebula guys answer this part ;-)

Regards.

[one-users] search with data from custom fields

[vincent]

Hi,

I wondered if it was possible to search for instances based on
data entered in extra or custom fields.

We generate a random name for the instance which makes it harder
to find an instance. We do however enter something in the description
field. Is it possible to do a query bqsed on this?

It would also be nice to have a query field where you can do a search
with multiple factors like give all centos7 machines with 4GB RAM.

Thanks,
Vincent
