[PATCH] KVM test: Release memory after testing with hugepages

From: Amos Kong <akong <at> redhat.com>

After testing with hugepages, memory is not released, it will cause the memory
lack in host. This will make the host running extremely slow and will influence
other tests to be executed.

post_command is executed after every test. This means that at the end of
the boot test for example, while the VM is still alive, the command will
be executed.  Won't that bother the VM?

Certainly we can. In actuality, that's what's being done on our internal
autotest server - this particular test is linked to the upstream bug
https://bugs.launchpad.net/qemu/+bug/599958

We've discussed about this issue this morning, it boils down to the way
people are more comfortable with handling this issue. My first thought
was to disable HPET until someone come up with a time drift mitigation
strategy for it.

But your approach makes more sense, unless someone has something else to
say about it, I'll drop the patch from autotest shortly.
