---Problem Description---
Incomplete Product details of the NVIDIA GPU in the guest , after pass-through.
The below NVIDIA GPU is present on the host which is later pass-through'ed to guest.
On Host:
0004:04:00.0 3D controller [0302]: NVIDIA Corporation GV100GL [Tesla V100 SXM2 32GB] [10de:1db5] (rev a1)
0004:05:00.0 3D controller [0302]: NVIDIA Corporation GV100GL [Tesla V100 SXM2 32GB] [10de:1db5] (rev a1)

After the passthrough the adapter is listed as below in the guest:
0001:00:10.0 3D controller [0302]: NVIDIA Corporation Device [10de:1db5] (rev a1)
0001:00:11.0 3D controller [0302]: NVIDIA Corporation Device [10de:1db5] (rev a1)

The complete product information : GV100GL [Tesla V100 SXM2 32GB is missing in the guest pci details.

The complete product information is essential for user awareness of the device model.

The expected output in the guest should be:
0001:00:10.0 3D controller [0302]: NVIDIA Corporation GV100GL [Tesla V100 SXM2 32GB] [10de:1db5] (rev a1)
0001:00:11.0 3D controller [0302]: NVIDIA Corporation GV100GL [Tesla V100 SXM2 32GB] [10de:1db5] (rev a1)

Snip of hardware details of 1 GPU on host and guest:

A debugger is not configured

---Steps to Reproduce---
1. Configure the guest with GPU pass-through.
2. After the guest starts, check the pass-through'ed device details:

Hi,

The problem is the guest's pci ids database, located in /usr/share/misc/pci.ids. The GPU model "Tesla V100 SXM2 32GB", PCI ID 1db5, was added in the database on 2018-03-30:
https://github.com/pciutils/pciids/commit/d8c893dfff4d

The pci.ids version in the guests with Ubuntu 18.04 and 18.04.1 that I tested has an older version:

vm1:
user@ubuntu:~$ cat /etc/os-release | grep VERSION=
VERSION="18.04 LTS (Bionic Beaver)"
user@ubuntu:~$ cat /usr/share/misc/pci.ids | grep Version:
# Version: 2017.03.16

vm2:
user@ubuntu:~$ cat /etc/os-release | grep VERSION=
VERSION="18.04.1 LTS (Bionic Beaver)"
user@ubuntu:~$ cat /usr/share/misc/pci.ids | grep Version:
# Version: 2017.03.16

So, to lspci or lshw show this GPU model correctly, the pci.ids must be a version greater than or equal to 2018-03-30. A guest with Ubuntu 18.04.2 worked correctly, because:

vm3:
root@ubuntu:~# cat /etc/os-release | grep VERSION=
VERSION="18.04.2 LTS (Bionic Beaver)"
root@ubuntu:~# cat /usr/share/misc/pci.ids | grep Version:
# Version: 2018.07.21

To update this database manually, you can run "update-pciids".

Canonical,

This is an issue with stock Ubuntu 18.04.1. Is it possible to update the PCI ID database on this version?

Dropping to P3 to match S3, as there seems to be no reason for a P2 designation.

All Ubuntu version after the 18.04.2 version (18.04.4 is the newest image) has an updated version of PCI IDS database. So, we can close this issue.
