Ne2000 NIC uses ring buffer of NE2000_MEM_SIZE(49152) bytes to process network packets.

In case of -EAGAIN returned by update_refcount(), we should discard the cluster offset we were trying to allocate and request a new one, because in theory that old offset might now be taken by a refcount block. In practice, this was not the case due to update_refcount() generally returning strictly monotonic increasing cluster offsets. However, this behavior is not set in stone, and it is also not obvious when looking at qcow2_alloc_bytes() alone, so we should not rely on it.

When the VMDK is streamOptimized (or compressed), the next_cluster_sector must not be incremented by a fixed number of sectors. Instead of this, it must be rounded up to the next consecutive sector.

Sadly, some images may have more clusters than what can be represented using a plain int. We should be prepared for that case (in qcow2_check_refcounts() we actually were trying to catch that case, but since size_to_clusters() truncated the returned value, that check never did anything useful).

For updating the cache sizes, disabling lazy refcounts and updating the clean_cache_timer there is a bit more to do than just changing the variables, but otherwise we're all set for changing options during bdrv_reopen().
