TrueNAS Storage Plugin

[SInisterPisces]

I guess I'm not aware, is the native ZFS-iSCSI unable to store TPM disks?

TPM does not work over PVE's native ZFS over iSCSI implementation.

Hmm, weird. Nah, it works fine afaik. I've been using TPM+EFI+Q35 based VMs on it just fine.

Having looked at your code a bit I think your plugin manages iSCSI at a lower level than the native ZFS over iSCSI implementation. Proxmox relies on iscsidirect to make the connections.

iscsidirect in QEMU refers to using the built-in iSCSI initiator (via libiscsi) to allow a virtual machine to connect directly to an iSCSI Logical Unit Number (LUN). This bypasses the host operating system's storage stack, meaning the host does not mount the LUN; instead, QEMU manages the connection directly when the VM starts.

@warlocksyno are any versions of this close to or are being considered, "Ready for Production"?

Proxmox has added support for TPM storage for ZFS over iSCSI in qemu-server: 9.1.10

Confirmed this fix is now in the no-subscription repo. Confirmed working on my test systems.
