It allocates low memory for swiotlb. So that extra 72M allocation is the
disadvantage. With so many virtual machines on a single host, I don't
want to reserve extra 72MB on each virtual machine while I could
easily do away with memory reservation below 4G. 

So I do think that first trying memory below 896M, then below 4G and then
above 4G makes sense and we should modify crashkernel=X to handle that.

Thanks
