It seems to be down to:

which due to the changeset below which will cause the installer to
choose the -486 kernel.

Strangely the 686 kernel seems to work for you in dom0 and domU but I
guess you were just lucky somehow? Or is the changeset below too
general?

commit 66aeb43385f358ea05f23413d4de014529a243ef

    Use -486 flavour for all CentaurHauls processors
    
    As they lack long NOP instructions, -686 kernels since 2.6.22+ fail to
    boot on these processors even if they claim 686 compatibility.
