https://bugzilla.redhat.com/show_bug.cgi?id=1519130 Commit id 'dc692438' reverted the automagic addition of a SCSI controller attempt during virDomainHostdevAssignAddress; however, the logic to determine where to place the next_unit depended upon the "new" controller being added. Without the new controller the the next time through the call for the next SCSI hostdev found would result in the "next_unit" never changing from 0 (zero) and as a result the addition of the device will fail due to being a duplicate unit number of the first with the error message: virDomainDefCheckDuplicateDriveAddresses:$line : unsupported configuration: SCSI host address controller='0' bus='1' target='0' unit='0' in use by another SCSI host device So instead of walking the controller list looking for SCSI controllers, all we can do is "pretend" that they exist and allow other code to create them later as necessary.
Libvirt API for virtualization
Libvirt provides a portable, long term stable C API for managing the virtualization technologies provided by many operating systems. It includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER Hypervisor.
For some of these hypervisors, it provides a stateful management daemon which runs on the virtualization host allowing access to the API both by non-privileged local users and remote users.
Layered packages provide bindings of the libvirt C API into other languages including Python, Perl, PHP, Go, Java, OCaml, as well as mappings into object systems such as GObject, CIM and SNMP.

License
The libvirt C API is distributed under the terms of GNU Lesser General
Public License, version 2.1 (or later). Some parts of the code that are
not part of the C library may have the more restrictive GNU General

Installation
Libvirt uses the GNU Autotools build system, so in general can be built and installed with the usual commands. For example, to build in a manner that is suitable for installing as root, use:
$ ./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var
$ make
$ sudo make install
While to build & install as an unprivileged user
$ ./configure --prefix=$HOME/usr
$ make
$ make install
The libvirt code relies on a large number of 3rd party libraries. These will
be detected during execution of the configure script and a summary printed
which lists any missing (optional) dependencies.
Contributing
The libvirt project welcomes contributions in many ways. For most components the best way to contribute is to send patches to the primary development mailing list. Further guidance on this can be found on the website:
