I am aware of attaching volumes to instances and this is not what I 'd like to do.

I would like when I start an instance to be able to attach to it multiple ephemeral disks.

What Gary proposes looks fine to me but for the moment I am using libvirt and KVM.

Best,

George

That may provide some additional information
This is currently supported by libvirt and xen. There are patches in
review for Vmware. Not sure about the other drivers.
Thanks

Hi Georgios,

  I believe Gary refers to this:

http://docs.openstack.org/user-guide/content/attach_volume_to_instance.html
[14]

  Which is probably not exactly what you have in mind, but it might
still accomplish what you need,

Hi Gary!

Thanks for the feedback!

Can you be a little more specific how to implement that? How can I
setup a flavor with more than one ephemeral disk?

Regards,

George

Hi,
You are able to do this when you boot using block device
mappings. You can
have a number of ephemeral devices.
Thanks
Gary

Hi all!

A rather strange question:

Is it possible to have more than one ephemeral disks attached
on boot
at VM?

Can each flavors somehow have many ephemeral disks with
different size?

Best,

George
