So with your patch, even if host has no ECC support, you will still
tell guest that the memory has ECC?

Yes, but I don't think it's of great importance. I'm just pleasing a test with the simplest possible 1-line fix. Do you know of anything that actually cares (i.e. not just "shows it to the user") about that particular DMI field, and does something different if it reads "ECC"?

For that matter, hvmloader is already saying that the host is running at some number of megahertz, which does not make sense for virtualization because the host may be loaded and slow down the guest.
