Hi Guys,

Do I need to install/configure anything special for Proxmox 5.0 to see a PCI NVME disk?

I can't see any kernel modules activated for nvme or the actual disk itself. Any hints?

Code: 
root@bruce:~# modinfo nvme
modinfo: ERROR: Module nvme not found.

root@bruce:~# lsmod | grep nvm

Sadly mine is not so happy :(

hm must be bios issue in your case ... can you see device(s) in bios ? perhaps you need a bios update to operate also nmve disks ?
or have you plugged in the device on wrong pci slot ?
 
I think it depends on linux-kernel, if it supports your hardware (and to what extent). Sometimes not all features of new chipsets are supported. But if Debian can see it (you can try live-dvd), Proxmox should see it too...
 
WIth NVME disks, I sometimes needed to create GPT partition tables using a Ubuntu live CD first, before Proxmox can create partitions.
 
The next ISO include some NVMe related bug fixes.
(will be released on Monday next week)
