There are 256 x 32 loop of pci scan. That is too long if we dynamically
start/tear down the container, otherwise it is ok. Some people are
struggling reducing the VM booting time from seconds to milliseconds to
compete with container technology. Let us consider if we could optimize
For example, QEMU supports specifying bus/dev for a device in its
commandline, so could we assign fixed bus for virtio-net and ivshm
device? And for piix3, is it on bus 0/1?
