So I see two problems with that change:
1/ I think it depends on using OVMF, not on encrypted memory.
2/ You need the VARS file as discussed earlier.
I believe that a more robust solution would be:
1/ Add an OVMF option alongside "firmware", as well as OVMF_VARS
2/ When OVMF is specified, create a copy of the VARS file, and pass two -drive options, one for OVMF_CODE and one for the copied OVMF_VARS.
3/ When MemEncrypt is true, check that you ahve an OVMF given and no bios.

>> I did a quick look. The runtime apparently uses the -bios option when the firmware option is passed, not the -drive option as I thought it would. I'm not entirely sure you can boot OVMF that way. I don't have any idea at the moment why it worked with version 1.x. If you could share with me the 1.x qemu command line option with the firmware option, I'm curious to see what it is.
