April 2, 20251 yr Hello everyone, I wanted to use my Nvme only for a VM. At the moment the Nvme is an unassigned drive, and I've used it to create the disk of the VM. But this is not a real passtrough - I would like to know how to pass the whole Nvme (to gain the performance peak) to the VM. Thanks a lot in advance.

So I rewatched the video of SpaceInvadersOne: I've made following: Selected my NVME disk and binded it to VFIO : - Select the Nvme disk - at the bottom click on : bind selected to VFIO at Boot , then rebooted the server. - Created a new VM, where I selected the Nvme as a PCI device - Created a new VM , Nvme showed up as PCIE. - When I try to fire up the VM, following error appears:

Bind to VFIO so you can attach as a PCI device. or you can put the drive path in the disk location. paths are here. ls /dev/disk/by-id/

I will try to unbind it from VFIO, reboot the server and try through /dev/disk

If you plan to format in the VM use one without part as that is the first partion on the disk. Re pci passthru is your Bios up todate.

I've unmounted the Nvme from Unassigned Drives. Now I see: Nonetheless, when i try to add it to the VM, it doesn't work since it want a size. I still not get why VFIO didn't work since: But let VFIO apart for a moment. How exactly to do it with the ID? I've tried following: But...
April 2, 20251 yr Author I've now tried following: So putted the nvme0n1 (which is my NVME) directly as a /dev/ inside the config of the VM... VM fired up, and the ISO of windows was able to see the whole disk. I don't know If this is the correct way. I think I have to set something more to get the NVME working correctly tough...

Using /dev/nvmen1 should be fine but that could change if hardware is changed.

I've tried with the full path but somehow it won't start :-( But with /dev/nvme0n1 it's working. Performance arent so great in the end unfortunately ...do I have to change the <target dev='hdd' bus='sata' /> to bus=scsi or something?

It is using a device path on the host so will show as a disk not a pci device.

Still a little bit odd that it wasn't working as a VFIO though, since it's usable mapping the device path directly, do you think I made something wrong with the VFIO mapping? Or maybe I'm missing something there? The NVME is on it's own group: Mapped, I was able to install Windows SVR2025 on this disk (I've cleared it first). What's a little bit odd is that, when I stopped the VM it's shown as follow in the UD : Two partitions are shown as XFS - which is a little bit unclear to me. EDIT: I saw a threat with issue with passthrough, it seems related to the SM2263XT, and there is a possible workaround, but I dont quite know how to edit the xml in the correct way - and it seems not to be "so stable". So I will try to use the "normal mapping", without VFIO with this drive for the moment, and eventually use another NVME drive. Still wondering on the partitioning FILESYSTEM of the NVME when windows was installed. EDIT2: After redoing the whole thing with Mapped drive at the end it seems to show the right FS: Edited April 4, 20251 yr by TDA update

Looks like you cannot use the PCI ID but need to have an alias. This is unlikely to be removed if you change via the GUI.
