---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)

---Debugger---
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?
