Running a 'virsh vol-info' or 'virsh vol-list default --details' after the 'virsh vol-wipe' would 'reset' the internal view of the volume allocation. In any case, I've generated a patch upstream in order to refresh the volume (if there is a refreshVol backend API) after the wipe volume is successful. See: http://www.redhat.com/archives/libvir-list/2015-December/msg00085.html Initial patch review resulted in generation of a v2: http://www.redhat.com/archives/libvir-list/2015-December/msg00608.html which included some doc adjustments. After a bit of back and forth - the doc adjustments were removed. Patch has been pushed: $ git describe 80ca86e54d101508ba6f3c5affc420d946810331 CVE-2015-5313-36-g80ca86e $ version:libvirt-1.3.1-1.el7.x86_64 Verified and PASSED. steps: 1. # virsh vol-create-as --pool default --capacity 200M --allocation 100M --format raw test.img Vol test.img created 2. # virsh vol-info test.img default Name: test.img Type: file Capacity: 200.00 MiB Allocation: 100.00 MiB 3. # virsh vol-resize --pool default test.img --shrink 50M error: Failed to change size of volume 'test.img' to 50M error: invalid argument: can't shrink capacity below existing allocation 4. # virsh vol-wipe --pool default test.img Vol test.img wiped 5. # virsh vol-resize --pool default test.img --shrink 50M Size of volume 'test.img' successfully changed to 50M 6. # qemu-img info /var/lib/libvirt/images/test.img image: /var/lib/libvirt/images/test.img file format: raw virtual size: 50M (52428800 bytes) disk size: 0 7. # virsh vol-info test.img default Name: test.img Type: file Capacity: 50.00 MiB Allocation: 0.00 B Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
