Try to increase the limit, it should be bigger than the size of the disk you're trying to mount (or unlimited). If you don't have enough free memory in your guest you may also need to set /proc/sys/vm/overcommit_memory to 1. And don't be afraid, the memory is not actually consumed by cmsfs-fuse, it is just needed to pass several checks buried in the memory management of the Linux kernel.
