| Doc Text: |
Cause: Using the (very obscure and deprecated) 'iface' parameter when adding a drive.
Consequence: Libguestfs would hang.
Fix: Libguestfs has been fixed so it can understand a mix of different interfaces (iface parameters).
Result: Libguestfs no longer hangs.

It's a bug in the calculation of the appliance disk. The kernel command line has root=/dev/sdb but that device won't exist. /dev/vda is the virtio disk, and /dev/sda is the appliance disk. Just a note that this bug is similar but different: https://bugzilla.redhat.com/show_bug.cgi?id=892272 The current bug happens in the appliance backend.
