[SOLVED] How do you set up a VM with NVMe interface?

[piero.proietti]

To do some testing on a Linux installation program of mine, I would like to configure a VM with NVMe to test the operation on it.

I think I have done this previously - about a year ago - probably by editing the VM configuration files, but I don't remember and wasen't able to find informations.

Can anyone provide me with an example,

There is currently no way to do this directly in PVE via the GUI, but as you guessed, it can be done via the args parameter. Something in the form of this should work:

-drive file=/path/to/nvme1.img,if=none,id=NVME1 -device nvme,drive=NVME1,serial=nvme-1

More information can be found on the QEMU Wiki.

I tried this, commenting the line:

#scsi0: local:103/vm-103-disk-0.qcow2,iothread=1,size=32G

and adding the line:

-drive file=/var/lib/vz/images/103/vm-103-disk-0.qcow2,if=none,id=NVME1 -device nvme,drive=NVME1,serial=nvme-1

This is the configuration file on /etc/pve/qemu-server/103.conf

boot: order=scsi0;ide2;net0

Not working...

args: -drive file=/var/lib/vz/images/103/vm-103-disk-0.qcow2,if=none,id=NVME1 -device nvme,drive=NVME1,serial=nvme-1

OK, not is working, great!!! Thanks

At last I added bootindex=1 to have boot, and started it.

This is the final working configuration:

args: -drive file=/var/lib/vz/images/103/vm-103-disk-0.qcow2,if=none,id=NVME1 -device nvme,drive=NVME1,serial=nvme-1,bootindex=1
