The current ivshmem protocol uses 'long' for integers. But the

Instead, switch to using little-endian int64_t. This breaks the
protocol, except on x64 little-endian ho

Use irqfd for improving context switch when notifying the guest.
If the host doesn't support kvm irqfd, regular msi notifications are
still supported.
Note: the ivshmem implementation doesn't allow switching between MSI and
IO interrupts, this patch doesn't either.

Ensure that reads of the PMCCNTR_EL0 are monotonically increasing,
even for the smallest delta of two subsequent reads.

It does a lot,
It doesn't seem correct to call it for all checkpoints, but why
is it right for timerlist_run_timers?

It is not clear what separates REPLAY_ASYNC_EVENT_BH from other async
events. It seems to be an ordering issue, but then why do input events
not have to be looked up in the queue? It would be much simpler if they
are all handled the same way.

These are some comments I have about the record/replay code. I can
integrate these in your patches myself, but I need an ack/tested-by and
in some case more answers... Please take a look.

Instead of handling allocation, teach ivshmem to use a memory backend.
This allows to use hugetlbfs backed memory now.
