<DIV><PRE>Hi Arnaud,
It's really good to know that your team are proposing the vcenter driver with OVA+glance datastore backend support. Thanks for sharing the information. OVA would be a good choice which will benefit users by avoiding only use flat image limited from current driver.
But in my opinion, it may not conflict with deploying from template. From an end user perpective, if there are already a set of templates within vcenter, it's good for him to have openstack to deploy VM from it directly. He can touch an empty image in glance only with the metadata pointing to the template name. And boot vm from it. Also he can freely choose to generate a *ova with vmdk stream file and placed in certain datastore and deploy from VM from image location pointing to the datastore. These are two different usage scenarios per my understanding.
And to go further, if there are some mechnism, that openstack can sync exsiting VM templates into Glance images. It can make this function more useful. </PRE></DIV>

<DIV>Hi Qui Xing,<BR></DIV>
<DIV><BR></DIV>
<DIV>We are planning to address the vCenter template issue by levering the
OVF/OVA capabilities.</DIV>
<DIV>Kiran's implementation is tied to a specific VC and requires to add Glance
properties that are not generic.</DIV>
<DIV>For existing templates, the workflow will be:</DIV>
<DIV>. generate an *.ova tarball (containing the *.ovf descriptor + *.vmdk
stream-optimized) out of the template,</DIV>
<DIV>. register the *.ova as a Glance image location (using the VMware Glance
driver see bp [1]) or simply upload the *.ova to another Glance store,</DIV>
<DIV>. The VMware driver in Nova will be able to consume the *.ova (either
through the location or by downloading the content to the cache): see bp
[2]. However, for Icehouse, we are not planning to actually consume the *.ovf
descriptor (work scheduled for the J/K release).</DIV>

target=_blank>https://wiki.openstack.org/wiki/Meetings/VMwareAPI#Meetings</A> is
planning on working on that again for Icehouse-3 but there's some new debate on
the best way to implement the desired effect. The goal of that change would be
to avoid streaming the disk image out of vCenter for the purpose of then
streaming the same image back into the same vCenter. That's really inefficient.
<DIV><BR></DIV>
<DIV>So there's a Nova level change that could happen (that's the patch you saw)
and there's a Glance level change that could happen, and there's a combination
of both approaches that could happen.</DIV>
<DIV><BR></DIV>
<DIV>If you want to discuss it informally with the group that's looking into the
problem I could probably make sure you end up talking to the right people on
#openstack-vmware or if you pop into the weekly team meeting on IRC you could
mention it during open discussion time.</DIV></DIV>
