I am also seeing this behaviour on Ubuntu 16.04, linux- image-4.4.0-127-generic.
Swapping to kernel 4.13.0-43-generic solved it here too. Steps: $ qemu-img create -b example.qcow -f qcow2 /run/shm/temp1.qcow2 $ qemu-nbd -c /dev/nbd1 /run/shm/temp1.qcow2 $ mkdir /tmp/mnt1 $ sudo /bin/mount /dev/nbd1p2 /tmp/mnt1 mount: special device /dev/nbd1p2 does not exist I can do whatever other diag is needed, please let me know how I can help. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1761646 Title: Can't mount kvm image file on new kernel of 16.04(linux 4.4.0-119) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1761646/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
