Passing unformatted NVMe SSD to Windows VM - Noobie help

[BeGaDaButcher]

Hello Proxmox community,

Firstly need to declare that I am fresh to Proxmox but loving it so far!

I was wondering if I could get some guidance on how to pass though a unformatted/blank NVMe SSD to my Windows 2019 VM to manage. IE for the VM to see it as a additional HDD and let it format the drive.

Description of my system:

• Proxmox and VM installed on a 120GB SATA M.2.
• Unused NVMe 120GB SSD I want to completely pass onto the VM to manage (IE native NTFS - so if the VM/Host goes down I can just plug the Nvme into a windows system and browse its files)
• 6x 3TB HDD's of different models and makes running RaidZ2 as a network based storage solution. Not applicable for this VM or the query above but want to mention it for context and why I might be getting confused as my /de/disk/by-id/ is big.
• VM is up and running with no issues
• The NVMe I want to pass through was formatted with GParted - unallocated before setting up the Proxmox host

Here is my datacentre storage UI:


My by-id:


My VM config file:


Tried adding the drive via the GUI but guessing I need to add it via the shell.



Is it as easy as adding a line within the VM config to add the additional drive?

Thought I would ask as the host, RAIDZ2 share and VM are working perfectly right now so don't want to make a mistake.


Noob stuff I am sure but I really appreciate your time and help!

Cheers,
JKN

Hey,



there you should then be able to select the NVMe. You might have to remove it from storage of the node and probably reboot.

G'Day Hannes,

Thanks for your reply! PCI...of course...

Anyway that lead me to find that IOMMU was not detected --- was set in BIOS but not the modules. Once I fixed that I had another run at Physical Disk to KVM and understood the examples better and managed to pass it through to the VM!

Formatted and accessible within the VM now without issue!

Thanks!
