Re: [Openstack] manage personal instance from openstack
it looks like you have an old environment and want to transfer all the instance to your openstack environment. I used to do this for KVM instance by writing some scripts in nova-network environment.

Re: [Openstack] manage personal instance from openstack
Hi Jay, Many thanks for your prompt reply. I don't want to go via image registry way as it has overhead of two copies (copy to swift and then openstack copies image to host for launch). Rather I was thinking to launch an instance (using any image with same resources as my image), and then when I want to transfer my image, just replace image of instance on host. I know it may break couple of things, network being one. BUt I am trying to figure out what all can go wrong and fix it before (or after) I ave copied my image. Please let me know your thoughts on this route to tranfer instance.

If you have a Swift installation, it's quite easy. 1) Snapshot your instance in your VMWare or Virtualbox environment 2) Convert the snapshot to a format that the hypervisor used in your OpenStack environment supports (ISO or QCOW2 is easiest for KVM) 3) Upload your converted image into Swift 4) Issue a call to Glance to register your image from Swift: glance image-create --disk-format= --container-format= --location= The image will then appear in your tenant's list of images in Horizon or glance image-list, and you may use it to launch an instance. All the best, -jay p.s. You don't necessarily need to use Swift, either... you could always just place your converted image on a web server somewhere and replace with the URI of your image. ___ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp ___ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp

[Openstack] manage personal instance from openstack
Hi everyone, I have an instance running various applications in my environment and I want to transfer it to Openstack. One way is to take image of my instance, register it with Openstack image library and then create an instance out of it. I am wondering whether there can be a direct way to register it with Openstack. Please suggest me a good way to transfer my instance to Openstack.
