KVM TPM 2.0 passthough

[leeroy]

TrueNAS Scale: TrueNAS-SCALE-22.02.1

Is it possible to passthrough TPM 2.0 in KVM? This is straight forward'ish with hyper-v or vmware and not sure how to do this within scale/kvm.

You might want to consider Proxmox.

It supports individual device passthrough and TPM 2.0 emulation.

@elvisimprsntr yes, this is something we had considered. We were looking at consolidating down some of our servers and proxmox did come up. TrueNAS Scale on bare metal seems like it made the most sense at the time. But it appears the virtualization side of it may need some maturing? We were also looking at virtualizing Scale on Proxmox and port all the other VM duties to proxmox, but it appears that virtualizing TrueNAS is not advisable, but it appears folks have had success on that front...

Yeah. TrueNAS is a storage solution first. Hypervisors is not one of its strong areas. Maybe that will improve under SCALE, but at the moment it's not ready for mission critical VMs based on my experience.

@elvisimprsntr thanks for the help, much appreciated! Yes, it would be extremely handy if the virtualization side of it was better.
