After discussion I split the patches.
this patch adds autotest.libhugetlbfs test which tests hugepage support
inside of kvm guest.

This patch adds kvm_hugepage variant. It prepares the host system and
start vm with -mem-path option. It does not clean after itself, because
it's impossible to unmount and free hugepages before all guests are
destroyed.
There is also added autotest.libhugetlbfs test.
I need to ask you what to do with change of qemu parameter. Newest
versions are using -mempath insted of -mem-path. This is impossible to
fix using current config file. I can see 2 solutions:
1) direct change in kvm_vm.py (parse output and try another param)
2) detect qemu capabilities outside and create additional layer (better
for future occurrence)
