Sean Banko 7633d47293 vmm: prefault memory in parallel to optimize boot time ... On guests with large amounts of memory, using the `prefault` option can lead to a very long boot time. This commit implements the strategy taken by QEMU to prefault memory in parallel using multiple threads, decreasing the time to allocate memory for large guests by an order of magnitude or more. For example, this commit reduces the time to allocate memory for a guest configured with 704 GiB of memory on 1 NUMA node using 1 GiB hugepages from 81.44134669s to just 6.865287881s.
