Azure NV class:
4.11.0-1013:
jrp@jrpubuntuv:~$ lspci

bridge (AGP disabled) (rev 03)

983b:00:00.0 VGA compatible controller: NVIDIA Corporation GM204GL [Tesla M60]
(rev a1)
4.11 finds it fine, but NVIDIA's GRID driver doesn't support newer
kernels like 4.11.
4.4.0-97:
jrp@jrpubuntuv:~$ uname -r
4.4.0-97-generic
jrp@jrpubuntuv:~$ lspci
00:00.0 Host bridge: Intel Corporation 440BX/ZX/DX - 82443BX/ZX/DX Host bridge
(AGP disabled) (rev 03)
00:07.0 ISA bridge: Intel Corporation 82371AB/EB/MB PIIX4 ISA (rev 01)
00:07.1 IDE interface: Intel Corporation 82371AB/EB/MB PIIX4 IDE (rev 01)
00:07.3 Bridge: Intel Corporation 82371AB/EB/MB PIIX4 ACPI (rev 02)
00:08.0 VGA compatible controller: Microsoft Corporation Hyper-V virtual VGA
4.4.0-77, 79, 83, 87, 89, 91, 92, 93, and 96 also fail to find the
hardware.
These used to work, so I am also investigating on the host/hardware
side.
