Hello Ahmed,
good investigation: there's something I knew and something that I didn't.
As far as I understood, _base directory should be a cache for images, NOT a
directory used for instances.
I mean, compute nodes keep an image cache for preventing the download from
glance each and every time

Hi! The following description is libvirt specific. Bearing in mind that

Hello,
When you use a flavor with an ephemeral disk size different from zero, the
instance is booted with an extra virtual disk whose size is indicated by
the ephemeral value (in GB).
Using cirros image, try a flavor with ephemeral disk size different from
zero (you need to create one yourself
Hi Marco,
Thank you very much for the info, much much clearer. I was looking for the
boot disk using ls -l /dev/sd*, but the existence of /dev/vda1 should
have given me a clue.
A few follow up questions:
- I am assuming the space for the VM boot disk is allocated from the local
hard disk of
Hi Ahmed,
very technical questions.
I'm not sure my answers are right: I'm just an user...
In order to answer, I've just look at what happens and made some guess.
Feel free to verify yourself.
I'm assuming you are using KVM as I'm doing.
The space for the boot disk and the ephemeral disk
Sorry, the directory you need to check is /var/lib/nova/instances.

creating some instances to test out how/where the different storage related

I created two VM instance:
Instance 1 : 20GB boot disk
Instance 2 : 10GB boot disk, 2 GB Ephemeral disk.
Hello,
I instantiated a VM using the cirros image, using the pre-defined
m1.small (1 VCPU, 2 GB Ram, 20G boot disk, 0 Ephemeral disk). I then
logged into the console of the VM to view some system stats. The num of
CPU and memory makes sense, but I am a bit confused on the storage aspect.
