    Hi; John Snow tells me that this test fails in the tests/vm/netbsd
    VM (you can test this with 'make vm-build-netbsd') because the
    assert() on the ftruncate() call fails:

     > +    ret = ftruncate(fd, NPCM7XX_TEST_IMAGE_SIZE);
     > +    g_assert_cmpint(ret, ==, 0);

     > +#define NPCM7XX_TEST_IMAGE_SIZE (1 << 30)

    I haven't investigated the exact cause, but this is a
    gigabyte, right? That's a pretty massive file for a test case to
    create -- can we make the test use a more sensible size of
    sd card image ?


It looks like the nuvoton part had an issue with a smaller image size, but we can resurrect that thread and poke at it a bit and see what shakes out.

Could you use the null-co block driver instead?

    -blockdev driver=null-co,size=1G,read-zeroes=on,node-name=null0
    -device sd-card,drive=null0
