you may want to check if the storage is healthy, and the file exists and is healthy. Depending on what filesystem and primary storage you're using you may run fsck or equivalent to recover the corrupted file. You may also want to check file permissions. Can you share your CloudStack version, output of "virsh version", "qemu-img info" on the qcow2 file and KVM host distro.

To discuss further pl join the CloudStack users mailing list and ask there http://cloudstack.apache.org/mailing-lists.html
