Hi all
 
I have a problem when I use `virsh attach` to attach a qcow2 disk to vm without argument --subdirver=qcow2
and this makes the qcow2 disk become a raw format disk, and the data in this disk is missing in guest os
and also I have used guestmout to confirm this, the same result.
 
Is there any way to let me find back the data in this disk ?
 
the version of libvirt and kvm is :
 
Compiled against library: libvir 0.9.8
Using library: libvir 0.9.8
Using API: QEMU 0.9.8
Running hypervisor: QEMU 1.0.0
