I've just noticed that on a SPARC host, some of the PPC guests warn during make check:
/ppc64/prom-env/pseries: qemu-system-ppc64: System page size 0x2000 is not enabled in page_size_mask (0x11000). Performance may be slow Is this really a performance problem on a TCG guest? It makes the 'make check' output a bit noisy, but not unbearably so. thanks -- PMM
