To check any qemu-system-* emulator's expected pci bus naming:
$ qemu-system-ppc64 -nographic -nodefconfig -nodefaults -machine pseries
-monitor stdio
QEMU 2.0.0 monitor - type 'help' for more information
(qemu) Warning: Disabling some instructions which are not emulated by TCG (0x0,
0x4)
then use the command 'info qtree' which will print something similar to:
bus: main-system-bus
type System
dev: spapr-pci-host-bridge, id ""
index = 0 (0)
buid = 576460752840294400 (0x800000020000000)
liobn = 2147483648 (0x80000000)
mem_win_addr = 1102195982336 (0x100a0000000)
mem_win_size = 536870912 (0x20000000)
io_win_addr = 1101659111424 (0x10080000000)
io_win_size = 65536 (0x10000)
irq 0
bus: pci.0
type PCI
note the 'bus: pci.0' in the above output.
That will work for any qemu-system-* arch emulator. To find what
-machine types a specific arch emulator includes, try:
$ qemu-system-ppc64 -machine ?
Supported machines are:
taihu taihu
mac99 Mac99 based PowerMAC
pseries pSeries Logical Partition (PAPR compliant) (default)
