However, pSeries machines only support multiples of 256 MiB. Using 256 MiB of memory does not use more host memory than now, even for the migration test that starts two guests, and it allows running the test on pSeries too. This of course is not optimal, it would be nice to let the qgraph machine o= bject judge how much memory to provide. This is left for future work, together with a more generic framework that wraps the QEMU command line.
