The udev-generated /dev/disk/by-path names for virtio disks are broken on z 
Systems as they have the format virtio-pci-h.h.hhhh[-partn], where h.h.hhhh is 
the CCW devno of the virtio device representing the whole disk. Historically, 
the standard CCW naming was applied, which was ccw-h.h.hhhh[-partn]

Machine Type = 2964-703 running KVM for IBM z Systems 
 
---Debugger---
A debugger is not configured
 
---Steps to Reproduce---
1. Install Ubuntu LTS 16.04.1 on KVM for IBM z Systems 1.1.1
2. Issue ls -l /dev/disk/by-path
 
Userspace tool common name: udev 
 
The userspace tool has the following bit modes: 64-bit 

Userspace rpm: udev

Userspace tool obtained from project website:  na

There are basically two problems with this:
1. The naming is technically incorrect, since the virtio devices on z are no 
PCI devices but CCW devices
2. Then naming based on virtio- is backwards incompatible. This may seem not to 
be an issue for Xenial but customers may be confused if they have been running 
Linux on KVM for IBM z before.
