This is a legacy behavior in QEMU. There are a number of legitimate use cases where a user may only have read access to an image and as long as that image is mounted read-only, everything will work okay.
Virtio and SCSI will expose the read-only attribute to the guest so it should be very obvious what's happening. Unfortunately, IDE does not support the concept of read-only. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/658610 Title: Check whether images have write permissions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
