I seem to recall "guest hung". 99% of solaris hangs (without
a crash dump) are "hardware" in nature. (my experience backed by
an uptime of 1116days) so the finger is still
pointed at VirtualBox's "hardware" implementation.
as for ZFS requiring "better" hardware, you could turn
off checksums and other protections so one isn't notified
of issues making it act like the others.
Maybe not better hardware, but honest hardware. Every piece of software
depends to some extent on the devices it uses honouring their
contracts. ZFS has to trust the storage to have committed the data it
claims to have committed in the same way it has to trust the integrity
of the RAM it uses for checksummed data.
That's the price you pay for end to end checksums.
