How did you test this? Have you checked the QCOW2 image after copy-on-write with "qemu-img check"? There's some existing issues that seem to cause corruption which is why we're forcing read-only. It'd be nice to fix those issues before adding more features. ;-) Pekka -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
