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 not implemented in the bhyve driver, force each disk to have PCI address generated if it was not specified by user. --- src/bhyve/bhyve_device.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/src/bhyve/bhyve_device.c b/src/bhyve/bhyve_device.c index 8373a5f..ca30e9f 100644 --- a/src/bhyve/bhyve_device.c +++ b/src/bhyve/bhyve_device.c @@ -107,7 +107,8 @@ bhyveAssignDevicePCISlots(virDomainDefPtr def, } for (i = 0; i < def->ndisks; i++) { - if (!virDeviceInfoPCIAddressWanted(&def->disks[i]->info)) + if (def->disks[i]->info.type == VIR_DOMAIN_DEVICE_ADDRESS_TYPE_PCI && + !virPCIDeviceAddressIsEmpty(&def->disks[i]->info.addr.pci)) continue; if (virDomainPCIAddressReserveNextSlot(addrs, &def->disks[i]->info, -- 2.9.2
