Public bug reported:

Full command: qemu-system-x86_64 -enable-kvm -cpu host -smp cores=4 -m
4G -net bridge -net nic -full-screen -drive
file=ovmf_x64.bin,format=raw,if=pflash -drive
file=disks/win16_ide.img,format=raw,cache=none,aio=native -drive
file=disks/one.img,if=none,format=qcow2,id=one -drive
file=disks/two.img,if=none,format=qcow2,id=two -device
nvme,drive=one,serial=E86C3CFC43518D6F -device
nvme,drive=two,serial=2BDAC262CF831698

QEMU version: 2.5.0

Kernel: 4.5.1 (Arch Linux)

When there are two NVMe devices specified, only the second one will be
usable in Windows. The following error is shown under "Device status" of
the failed NVMe controller in Device Manager:

"This device cannot start. (Code 10)

The I/O device is configured incorrectly or the configuration parameters
to the driver are incorrect."

The only thing seems suspicious to me is that the nvme emulation in qemu
does not have WWN/EUI-64 set for the devices, though I have no idea at
all whether that is mandatory:

You can see from the "SCSI name string" that the working NVMe device is
the second one specified in the command.

"if=virtio" (which similarly has one controller per drive and has each
controller occupies a pci slot as the nvme emulation) works fine:

I also tested WIndows installation ISOs instead as well.

Windows 10 Enterprise 10586:

qemu-system-x86_64 -enable-kvm -cpu host -smp cores=4 -m 4G -net bridge
-net nic -full-screen -drive file=ovmf_x64.bin,format=raw,if=pflash

nvme,drive=one,serial=E86C3CFC43518D6F -device
nvme,drive=two,serial=2BDAC262CF831698

Windows Server 2016 Technical Preview 5:

qemu-system-x86_64 -enable-kvm -cpu host -smp cores=4 -m 4G -net bridge
-net nic -full-screen -drive file=ovmf_x64.bin,format=raw,if=pflash

nvme,drive=one,serial=E86C3CFC43518D6F -device
nvme,drive=two,serial=2BDAC262CF831698

Both of them shows only one of the NVMe drives.

I also tested with two versions of OVMF, which are "18419"
(https://github.com/tianocore/edk2/commit/ddd097e33f6e6829dc0413820e9971f3bf025f87)
and "18455"
(https://github.com/tianocore/edk2/commit/59844e126614fc8275aab083fafa5818cde0901c).

Thanks for the report. Sounds like a Windows specific issue as I have no
problem with multiple nvme drives on my dev machines:

These are not mandatory. They were only introduced in the 1.1 and 1.2 versions
of the NVMe spec, though we only cared to emulate the 1.0 portions rather than
provide a full featured NVMe controller.

That said, there needs to be care in the host OS to provide an appropriate
translation IF it is using a SCSI stack to talk to NVMe. Linux doesn't care,
but Windows does.

The above looks reasonable for your second controller that had serial
2BDAC262CF831698.

This doesn't look like a very good SCSI-NVMe translation and possibly
suspicious. But I don't know the first thing about windows; does it care about
unique unit serial numbers in order to surface a "SCSI" disk?

I checked your serial number against the SNT refernce on nvmexpress.org and
it's definitely the wrong translation, so that has to be a guest OS driver bug
(Linux has the right translation if interested, but it's use is deprecated).

I pinged some Windows comrades to see if a potential serial conflict prevents
both disks from surfacing.

I'm surprised to see this bad translation as I know of folks successfully
testing multiple nvme drives in various versions of Windows with both the OFA
and Microsoft drivers. An emulated NVMe is no different than real h/w for
namespace identification from the host's perspective.

The problem still exists with qemu 2.7.0 and Windows 10 RS1. Btw I just
did one more test, that I disable the working nvme controller in Device
Manager to see if it makes the non-working one comes alive, but it does
not, even if I reboot the virtual machine.

For the record, the serial number translation is not fixed in RS1
either.

Trying it on Windows 10 guest and QEMU 2.8.0 has the same issue. However, I noticed that:
  Supplying 1 NVMe drive -> Win10 sees it.
  Supplying 2 NVMe drives -> Win10 sees only one of them.
  Supplying 3 NVMe drives -> Win10 sees only two of them.
So I still have been able to create a ReFS mirrored storage space with two NVMe disks under QEMU, I just had to pass three drives instead of two:

qemu-system-x86_64 -enable-kvm <...> -drive
file=/media/ssd/NVMe_drvA.qcow2,id=diskNVMeA,format=qcow2,if=none -drive
file=/media/ssd/NVMe_drvB.qcow2,id=diskNVMeB,format=qcow2,if=none -drive
file=/media/ssd/NVMe_drvC.qcow2,id=diskNVMeC,format=qcow2,if=none
-device nvme,drive=diskNVMeA,serial=foo -device
nvme,drive=diskNVMeB,serial=foo -device nvme,drive=diskNVMeC,serial=foo

Hope this helps,

Hello, I can also confirm that if you have a series of NVMe devices, at
first when just the OVMF boot menu has loaded, using qemu with a
-monitor and typing 'info pci', it appears that all are given valid bus
addresses.

However, once the Windows 10 x64 installer iso loads, it seems that
every other NVMe device stays initialized correctly, but the ones in-
between switch to a 0xfffff... bus address. So, for example, with 6
devices, numbers 1,3,5 will get initialized and recognized by the
Windows installer, and 2,4,6 will not. Not sure if this clue helps
identify this a qemu or Windows issue or not, but I thought it was worth
noting.

Also, I found that an alternative way to getting two or more NVMe
devices successfully recognized by Windows is to use multiple root PCIe
devices like so:

qemu-system-x86_64 \
-enable-kvm \
-machine pc-q35-2.11,accel=kvm \
-nodefaults \
...
-device pcie-root-port,id=pcie_r0,bus=pcie.0,chassis=0,slot=0 \
-device nvme,drive=disk0,serial=serial0,bus=pcie_r0 \
-drive id=disk0,if=none,media=disk,cache=none,aio=native,format=raw,discard=unmap,file=/opt/os.raw \
-device pcie-root-port,id=pcie_r1,bus=pcie.0,chassis=0,slot=1 \
-device nvme,drive=disk1,serial=serial1,bus=pcie_r1 \
-drive id=disk1,if=none,media=disk,cache=none,aio=native,format=raw,discard=unmap,file=/opt/data.raw \

The QEMU project is currently considering to move its bug tracking to another system. For this we need to know which bugs are still valid and which could be closed already. Thus we are setting older bugs to "Incomplete" now.
If you still think this bug report here is valid, then please switch the state back to "New" within the next 60 days, otherwise this report will be marked as "Expired". Or mark it as "Fix Released" if the problem has been solved with a newer version of QEMU already. Thank you and sorry for the inconvenience.

** Changed in: qemu
       Status: New => Incomplete

Title:
  Only one NVMe device is usable in Windows (10) guest

Status in QEMU:
  Incomplete

Bug description:
  Full command: qemu-system-x86_64 -enable-kvm -cpu host -smp cores=4 -m
  4G -net bridge -net nic -full-screen -drive
  file=ovmf_x64.bin,format=raw,if=pflash -drive
  file=disks/win16_ide.img,format=raw,cache=none,aio=native -drive
  file=disks/one.img,if=none,format=qcow2,id=one -drive
  file=disks/two.img,if=none,format=qcow2,id=two -device
  nvme,drive=one,serial=E86C3CFC43518D6F -device
  nvme,drive=two,serial=2BDAC262CF831698

  QEMU version: 2.5.0

  Kernel: 4.5.1 (Arch Linux)

  When there are two NVMe devices specified, only the second one will be
  usable in Windows. The following error is shown under "Device status"
  of the failed NVMe controller in Device Manager:

  "This device cannot start. (Code 10)

  The I/O device is configured incorrectly or the configuration
  parameters to the driver are incorrect."

  The only thing seems suspicious to me is that the nvme emulation in
  qemu does not have WWN/EUI-64 set for the devices, though I have no
  idea at all whether that is mandatory:

  "C:\Windows\system32>sg_vpd -i PD1
  Device Identification VPD page:
    Addressed logical unit:
      designator type: SCSI name string,  code set: UTF-8
        SCSI name string:
        8086QEMU NVMe Ctrl                          00012BDAC262CF831698

  C:\Windows\system32>sg_vpd -p sn PD1
  Unit serial number VPD page:
    Unit serial number: 0000_0000_0000_0000."
