<p>I agree with Daniel for the qemu-img commands. For other temp file usage, I know on Fedora/RHEL there's already /var/lib/nova/tmp which is used for lock files, etc.</p>

In the particular case of the qemu-img command described<br>
in earlier in this thread, I'm not convinced we need a<br>
new option. Instead of using /tmp when extracting a snapshot<br>
from an existing disk image, it could just use the path<br>
where the source image already resides. ie the existing<br>
FLAGS.instances_path directory, which can be assumed to<br>
be a suitably large persistent data store.<br>
<br>
Other uses of temporary files should be analysed ona case<br>
by case basis to figure out a suitable storage location.<br>
This might perhaps identify a need for a generic temp<br>
file location for nova, such as /var/run/nova/ or<br>
/var/cache/nova or both (depending on use case).<br>
<br>
