Dear all,
we noticed that if apic-demo does not perform
comm_region->cell_state = JAILHOUSE_CELL_SHUT_DOWN;
at the shutdown request, then the jailhouse console hangs the whole system.
Apparently, if an inmate misbehaves (e.g., by running an infinite loop),
it can hang the whole system when trying to shutdown/destroy the cell.
To increase fault tolerance, shouldn't jailhouse have some kind of timer,
after while it forces cell destruction even if the cell has not set
JAILHOUSE_CELL_SHUT_DOWN ?
Best regards,
Claudio
