[Openstack] Image snapshot creation

Hi!

I'm just trying to clarify my understanding of the image snapshot creation
process.

When snapshotting a running instance, the compute node must have sufficient
disk space for the image to be created prior to uploading to Glance. Is
this correct?

Also, by default, during the snapshot creation on the compute node, where
is the snapshot image being written? /tmp? /var/nova/instances?

Thanks for your help!

Regards,
Ross
