Hi,
Perhaps system migration could be enhanced to support comparison of
states of guest systems in two QEMUs running on different CPU hosts.
Both emulators would send their state to a third one that just
receives both states and does the comparison. This could aid finding
bugs in host support.
Obviously for the comparison to be meaningful, the states need to be
taken at the same point of execution and interrupts should be
delivered deterministically, clocks synchronized etc. Maybe it gets
too complex.
