*** Bug 1529035 has been marked as a duplicate of this bug. ***
My bug 1529035 was marked as a duplicate of this, but I have libvirt-3.7.0-3.fc27 on my system and still have a problem with guestmount --ro no longer working in fedora 27 on a live VMs disk image (more details in bug 1529035). Is this really the same as my bug?
Tom, if you're still hitting issues, please reopen your old bug or file a new one
