Btw, what setup are you using to test memory errors? It would be
nice to have it documented somewhere, maybe at
docs/specs/acpi_hest_ghes.rst.

I don't think docs/specs/acpi_hest_ghes.rst is the right place for that
as it's for specifications.

Perhaps not, but it would be nice to have it documented somewhere,
either there or at QEMU wiki.

QEMU wiki may be the best place for it. I never updated to QEMU wiki and
any guiding steps on how to do that?

I'm sharing how this is tested here to make the thread complete.

Thanks!

- Trigger 'victim -d' in the guest

Hmm... from where I can get victim?
