[KVM_AUTOTEST] add autotest.libhugetlbfs test

2009-07-10 Thread Lukáš Doktor 

After discussion I split the patches.

this patch adds autotest.libhugetlbfs test which tests hugepage support 
inside of kvm guest.


Tested by:ldok...@redhat.com on RHEL5.4 with kvm-83-72.el5

Dne 9.7.2009 11:24, Lukáš Doktor napsal(a):

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)

This looks pretty clear now as the two patches do two different
things. The guest large pages support is completely independent of the
host support of large pages for the guest.
patches look good to me. thanks for splitting them.
