It's a long story before I came here to ask this question. In short, I am trying to passthru the GPU to a guest OS (an OMV5 instance). I followed the official instruction(, but failed while starting up the OMV instance due to BIOS was set to "OVMF" mode. So googled and found this official guide: Tried to follow the guide to fix the UEFI boot option on OMV instance, but I failed at step 2. It's empty in the file explorer! My screenshot as below:

Can somebody tell what's going on here? I'm a real novice to PVE, just started from last week.
Thanks in advance!
Did you install OMV5 correctly? I suspect it should support UEFI natively, if not that is a bug in OMV, not PVE...
I've solved the problem. The previous OMV installation was installed with GRUB, so there wasn't UEFI boot file. I reinstalled OMV5, and chose UEFI mode this time, the problem solved after installation complete.
Anyway, thanks for your reply.:D
