qemu has support for triggering MCEs on the monitor.

Also the KVM code base has support for forwarding the MCEs automatically.

KVM has all of the information you need (guest physical -> host physical mapping). It can also pin the mapping making it much safer to interface at that level. You should probably add an ioctl interface to KVM to get a host physical from a given guest physical and then use that to do the MCE injection. You would need to write a little helper tool and you would need a way to get an fd for an existing guest.

It would be simpler to trigger the whole thing from within qemu.
