This test case is currently working but it uncovers existing issue
|
|
|
9c6c51 |
in our code that the generated QEMU commandline uses the default 1G
|
|
|
9c6c51 |
hugepage instead of the 2M hugepage specified for exact node.
|
|
|
9c6c51 |
|
|
|
9c6c51 |
The issue in our code is that for non-numa guests we take into account
|
|
|
9c6c51 |
only the first hugepage. This will be fixed as invalid configuration
|
|
|
9c6c51 |
since it doesn't make any sense to set default and specific hugepage
|
|
|
9c6c51 |
for non-numa guest.
