kvm: Introduce support for -mem-path
Using hugepages, KVM instances can get a good performance boost. To
activate that, we need to pass the -mem-path argument to KVM along with
the mount point of the hugetlbfs file system on the node.
For the sake of memory availability computation, we use the -mem-prealloc
argument when enabling hugepages, so KVM will reserve all hugepages it
needs when it starts. This avoids allocating an instance on a node that
will not have enough pages in case other instance needs more than what
is available after it boots.
