What were you trying to do that didn't work?
snpguest generate measurement cannot use --ovmf and --ovmf-hash simultaneously.
But from snpguest doc, it says "A user can use a pre-calculated ovmf-hash using [--ovmf-hash], but the ovmf file still has to be provided."

Please provide the package NVR for which bug is seen:
snpguest-0.8.3-1.el9.src.rpm

How reproducible:
100%

Steps to reproduce
#snpguest generate measurement --vcpu-type EPYC --ovmf /usr/share/edk2/ovmf/OVMF.amdsev.fd --ovmf-hash /home/ovmf-hash --measurement-file /home/measurement-file

Expected results
generate measurement successfully

Actual results
error: the argument '-ovmf <ovmf>' cannot be used with '-ovmf-hash <ovmf-hash>'

Additonal
cannot use --ovmf-hash alone
snpguest generate measurement --ovmf-hash /home/ovmf-hash --vcpu-type EPYC --measurement-file /home/measurement-file
error: The following required argument was not provided: ovmf
