[CentOS-virt] Where are snapshots stored??

[C. L. Martinez]

HI all,

 I have created a snapshot for a kvm guest but only for one of disks
assigned to it:

 qemu-img snapshot -c osvol_base /vmachines/vmtst/osvol.img

and qemu-img snapshot shows me:

 Snapshot list:
ID        TAG                 VM SIZE                DATE       VM CLOCK
1         osvol_base                0 2013-08-29 11:37:23   00:00:00.000

It seems ok, but where is this snapshot stored?? I didn't find it ...
