Another small question. I noticed that all block drivers call
block_init ("module_init") and qemu_system binary has the
"--enable-modules" command line option.
But does QEMU support building block drivers outside the main source
tree ? And can I load a new block driver module into running QEMU
system - like the Linux kernel allows ? Or do I have to distribute
an entire own QEMU image if I add a new driver ? I am not sure if
what I am asking is the same as https://wiki.ubuntu.com/QemuDiskHotplug
No, this is a different question. Disk hotplug is something for the
guest, whereas you want something for the host. As far as I know, people
are aware of that issue and it may be implemented at some point in time.
But right now it's not supported in vanilla qemu (I've heard something
about at least one distribution already having implemented this).
If you add a new driver, you either have to distribute its source so
people can build qemu themselves with the driver included; or you build
qemu yourself and then distribute the binary; or you find your driver
good enough to submit it for upstream qemu.
