Thread-topic: [Xen-devel] [PATCH] tweak memory error correction field in the SMBIOS data
So with your patch, even if host has no ECC support, you will still tell guest 
that the memory has ECC?

Generally, I don't think it is a good idea to present guest with capability 
more than host can provide, unless you can provide that capability through 
software emulation.
But I don;t think you can emulate ECC memory through software method.
