Re: [openstack-dev] Manual VM migration

Hi Naveed, we have customers running VMs in their own Private Cloud that are migrating to our new Public Cloud offering. To be honest I would love to have a better way to do it, but this is how we do. We have developed a tiny script that basically performs the following actions: 1) Take a snapsho

Hi Diego, we have a push button technology that does all of that, plus a few additional things. Please look at our talk here https://www.youtube.com/watch?v=NW_D9bEsHAk&feature=shared On Wed, May 21, 2014 at 11:17 PM, Diego Parrilla Santamaría < diego.parrilla.santama...@gmail.com> wrote: > Hi N

Re: [openstack-dev] Manual VM migration

Are you sure steps 1 and 2 aren’t in the wrong order? Seems like if you’re going to halt the source VM you should take your snapshot after halting. (Of course if you don’t intend to halt the VM you can just do your best to quiesce your most active writers before taking the snapshot and hope the

Re: [openstack-dev] Manual VM migration

I have devstack based Openstack cloud on two different machines. I am interested to migrate instance from A to B devstack cloud. I tried to copy instance files from Cloud A ( ../../data/nova/instace--ab-cd-ef ) to Cloud B. I am also copying related metadata of instance from its database to destin

Re: [openstack-dev] Manual VM migration

Hi Diego , Thanks for sharing steps for VM migration from customer end to your cloud. Well! i am not going to propose new idea for VM migration. I am using VM migration for POC of my research idea. I have few question for you! 1. Can we use suspend/pause feature instead of snapshot for saving

Re: [openstack-dev] Manual VM migration

Hi Naveed, I don't think it's a good idea to suspend/pause. If you want to keep the state of the VM then have a look at the live migration capabilities of KVM. Our script is very simple and works for any VM without attached block storage. Here goes the little script. Keep in mind it's something v

Re: [openstack-dev] Manual VM migration

Hi, Thanks for response and sharing script. Can i use this script with devstack based cloud platform.? Actually Live Migration is available between inter-cluster. so that why i was talking about the suspend/pause the VM before migration. Regards On Thu, May 22, 2014 at 8:45 PM, Diego Parri
