tests: introduce hugepages-default-1G-nodeset-2M
This test case is currently working but it uncovers existing issue in our code that the generated QEMU commandline uses the default 1G hugepage instead of the 2M hugepage specified for exact node. The issue in our code is that for non-numa guests we take into account only the first hugepage. This will be fixed as invalid configuration since it doesn't make any sense to set default and specific hugepage for non-numa guest. Signed-off-by: Pavel Hrdina <phrdina@redhat.com>
