Hello,<br>
<br>
For the first point, yes, you need the free space disk necessary to
snapshot on the compute node. The process of snapshotting is in fact
a qemu-img creation, you can easily see the process details on the
compute node when you trigger a snapshot.<br>
<br>
However for the second point I don't remember right now where it's
placed before being transfered, you'll find out easily with the
qemu-img parameters.<br>
<br>
Hope it helps,<br>

<div><br>
</div>
<div>I'm just trying to clarify my understanding of the image
snapshot creation process.</div>
<div><br>
</div>
<div>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?</div>
<div><br>
</div>
<div>Also, by default, during the snapshot creation on the
compute node, where is the snapshot image being written? /tmp?
/var/nova/instances?</div>
<div><br>
</div>
<div>Thanks for your help!</div>
<div><br>
</div>
<div>Regards,</div>
