This is another manifestation of https://bugzilla.redhat.com/show_bug.cgi?id=890291 When libvirt is run as root, it runs qemu as a non-root qemu.qemu user which cannot access everything that root can. One solution here is *not* to run virt-sparsify as root at all, since it doesn't need to be. *** This bug has been marked as a duplicate of bug 890291 *** |
