When a CAPI card experiences an EEH event, any cache lines it holds are filled with SUEs (Special UEs, interpreted by the kernel the same as regular UEs). When these are read, we get an MCE. Currently CAPI does not support virtualisation, but that is actively being worked on. There's a _very_ good chance it will then be backported to various distros, which could have old qemu. Therefore, I'd ideally like to make sure UEs in KVM guests work properly and continue to do so in all combinations of kernel and qemu. I'm following up the email from Mahesh that you linked: I'm not sure I quite follow his logic so I'll try to make sense of that and then get back to you. Regards, Daniel
