As bhyve currently doesn't use controller addressing and simply uses 1 implicit controller for 1 disk device, the scheme looks the following: pci addrees -> (implicit controller) -> disk device So in fact we identify disk devices by pci address of implicit controller and just pass it this way to bhyve in a form: -s pci_addr,ahci-(cd|hd),/path/to/disk Therefore, we cannot use virDeviceInfoPCIAddressWanted() because it does not expect that disk devices might need PCI address assignment. As a result, if a disk was specified without address, it will not be generated and domain will to start. Until proper controller addressing is implemented in the bhyve driver, force each disk to have PCI address generated if it was not specified by user.
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
