SLOF is unfortunately quite slow when running with TCG, so the pxe test is also performing rather slow here. By using "-nodefaults" we can disable some devices (vscsi) that we are not interested in here, so that SLOF does not have to scan them during boot and thus starts up a little bit faster. The ppc64 pxe-test now only takes 27 seconds on my laptop instead of 33 seconds. The "-nodefaults" flag seems to work fine for the x86 tests, too, so it is added here unconditionally here (though there is no speed-up on x86 by using this flag).

David: Since you did not send a pull request for the patch that introduces the ipv6/ppc64 test yet, feel free to squash this patch into that original patch in your queue if you prefer that instead of two separate patches. tests/pxe-test.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/tests/pxe-test.c b/tests/pxe-test.c index 0bdb7a1..5d3ddbe 100644 --- a/tests/pxe-test.c +++ b/tests/pxe-test.c @@ -25,7 +25,7 @@ static void test_pxe_one(const char *params, bool ipv6) { char *args; - args = g_strdup_printf("-machine accel=tcg -boot order=n " + args = g_strdup_printf("-machine accel=tcg -nodefaults -boot order=n " "-netdev user,id=" NETNAME ",tftp=./,bootfile=%s," "ipv4=%s,ipv6=%s %s", disk, ipv6 ?
