+description = """The default causes problems if you enable any non-legacy VirtIO device which has the VIRTIO_F_VERSION_1 feature bit will not properly read all feature bits. This is because reading VIRTIO_MMIO_VERSION returns VIRT_VERSION_LEGACY which in turn results in the driver not reading all feature bits, e.g. the qtest access:

+```
+static uint64_t qvirtio_mmio_get_features(QVirtioDevice *d)
+{
+    QVirtioMMIODevice *dev = container_of(d, QVirtioMMIODevice, vdev);
+    uint64_t lo;
+    uint64_t hi = 0;
+
+    qtest_writel(dev->qts, dev->addr + QVIRTIO_MMIO_HOST_FEATURES_SEL, 0);
+    lo = qtest_readl(dev->qts, dev->addr + QVIRTIO_MMIO_HOST_FEATURES);
