[Bug 1576347] Re: Only one NVMe device is usable in Windows (10) guest

[Thomas Huth]

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

  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:
