How and what did you notice?

Orthogonally to whether we should improve x86 testing on 32-bit
hosts, IIRC this isn't the first time we have an issue with SEV
(or more generically Confidential Computing) on 32-bit host, so
I wonder if this is a feature worth testing & supporting there
(thus Cc'ing more maintainers).
