That's correct.  If there's an .ovf, it's currently ignored.  It's also not generated when we upload images (snapshots).  I'm sure there's plans in someone's head to implement that support at some point.. but right now we expect the .vhds to have specific names in the tar file.

Paul:

I assume you're using XenServer? When I grepped through the code, there appears to be a XenServer plugin for glance for supporting tar balls that could be OVAs, but don't necessarily contain the OVF file (?).

Here's the code:

Lorin,

We've been using OVA packages since the beginning. I believe there is a flag in glance for this.


Thanks,

All:

Given that I have a qcow2 image from somewhere (e.g., downloaded
it from a uec-images.ubuntu.com<http://uec-images.ubuntu.com/>, created one from a raw image using
qemu-img) that i want to add to glance:

1. How can I tell whether it's an "ovf" or "bare" container format?

You are mixing up terminology here. Disk image formats are things like
raw, qcow2, vmdk, etc.

OVF refers to the format of a metadata file provided alongside the
disk image, which describes various requirements for running the
image.

The two are not tied together at all, merely complementary to
each other.


Thanks, that clears things up. I was confused by this language, which sounded to me like the metadata was embedded in the disk image file:

http://glance.openstack.org/formats.html

"The container format refers to whether the virtual machine image is in a file format that also contains metadata about the actual virtual machine."

In addition, the docs have examples like this, which clearly aren't meaningful:
http://glance.openstack.org/glance.html#important-information-about-uploading-images

Just to add to the confusion  the OVF can contain both the metadata file and the disk image file in a single archived file.

"An OVF package consists of several files, placed in one directory. A one-file alternative is the OVA package, which is a TAR file with the OVF directory inside."

http://en.wikipedia.org/wiki/Open_Virtualization_Format#Technical_description


Does anybody know if OpenStack (nova+glance) currently supports OVA packages?

Take care,

Lorin
