Hello,

I have a running KVM virtual guest "demo1" with a defined disk at path /guests/mydisk.img.

But when I run

conn = virConnectOpenReadOnly(NULL);
path = "/guests/mydisk.img";
virStorageVolLookupByPath(conn,path);

I got the error
"
ibvir: Storage error : invalid storage volume pointer in no storage vol with matching path
"

what am I missing ?
Thanks,
Francesco
