Hi,
Can QEMU emulate an OPAL disk? The only relevant thing I found is a post
from 2017 about TPM that mentions OPAL:
https://lists.gnu.org/archive/html/qemu-devel/2017-07/msg04586.html
specifically this bit:
Well, at some point somebody's going to want us to implement this,
but... they can do that when they do that.
So I assume it is not implemented. (?)
I agree with the sentiment expressed in the mail linked above w.r.t. OPAL
security. I'm interested in this from SW development/debugging/fiddling
perspective. A sufficient solution for me would not add any real
encryption but would respond to the various OPAL commands send via ATA
TRUSTED SEND/RECEIVE commands.
In fact, a more generic solution would work for me: If it was possible to
send ATA commands from QEMU to a separate process which could then handle
them as it liked and reply back to QEMU. This could be useful for other
fiddling/debugging situations too.
Or, just a pass-through to a block device in the host - but a pass-through
that would allow OPAL commands.
I'm grateful for any hints/ideas. Perhaps something like this is already
possible with QEMU?
Best regards,
David
