how instance storage work?
kvm-img create ubuntu_12.04_server.img 80G
On the compute node:
root@compute1:/# ls -lh /var/lib/nova/instances/183ee6d0-a363-46c9-952b-2fe38d3960c1(instance_id)**
total 7.0G
-rw-rw---- 1 libvirt-qemu kvm 1 Dec 17 17:17 console.log
-rw-r--r-- 1 libvirt-qemu kvm 7.0G Dec 19 16:51 disk

-rw-r--r-- 1 libvirt-qemu kvm 193K Dec 17 16:23 disk.swap

-rw-r--r-- 1 libvirt-qemu kvm 2.0G Dec 17 16:23 swap_2048
this the flavor:

I was confused by the directory _base
, especially the 5f9399500420f4a42ca62ae246660b311913c708
(79G).Is it the img file from glance? In the instance directory /var/lib/nova/instances/183ee6d0-a363-46c9-952b-2fe38d3960c1
,is the 'disk' file the device /dev/vda based on in the vm and what about the 'disk.local' file?
