services. Glance’s logs should be somewhere like /var/log/glance/. I only have api.log for glance. Cinder’s should be somewhere like /var/log/cinder/. I have api.log, backup.log, scheduler.log, and volume.log.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">In the glance configuration, you’re looking for the enabled_backends line in the [DEFAULT] section. If I remember correctly, it’s values has the form <name>:<type>.
The type is the interesting part.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Cinder is a little more difficult. You’re still going to be looking for an enabled_backends line, in the [DEFAULT] section, but it’s value is just a name (enabled_backends
= <name>). You need to locate a configuration section which matches the name ([<name>]). You’ll then be looking for a volume_driver line. Based on you response, I suspect this will be: volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver.<o:p></o:p></span></p>

I only see one issue with what you said, or perhaps didn't say. You are aware that it is a very good idea to sysprep --generalize a Windows instance, before making an image from it, yes?<br>
<br>

Subject: Problème with image from snapshot<br>
<br>
Hello and first sorry for my english… thanks google.<br>
<br>
Something is wrong with what I want to do:<br>
I use Wallaby, it works very well (apart from VpnaaS, I wasted too much time this summer to make it work, without success, and the bug does not seem to be fixed).<br>
<br>
Here is what I want to do and which does not work as I want:<br>
- With an admin account, I launch a Win10 instance from the image I created. The instance is working but it takes about 10 minutes to get Win10 up and running.<br>
I wanted to take a snapshot of this instance and then create a new image from this snapshot. And that users use this new image.<br>
I create the snapshot, I place the "--public" parameter on the new image.<br>
I'm trying to create a new instance from this snapshot with the admin account: it works.<br>
I create a new user, who has his project, and sees all the images. I try to create an instance with this new image and I get the message:<br>
<br>
Block Device Mapping is Invalid: failed to get snapshot f12c04f2-51e7-4817-ab9b-eda63c5b9aff. (HTTP 400) (Request-ID: req-c26dab86-c25f-409a-8390-8aa0ea8fe1cb)<br>
<br>
Is it a legal problem? Is it possible to do as I do? otherwise how should we do it?<br>
<br>
Thanks if you have ideas for helping me<br>
<br>
