Okay, I'll give it a try.
I tried the above but using the latest Raspbian Stretch Lite image
instead of Arch: the guest comes up with no issues and offers serial
console access, so that part works nicely.
However, I notice that you are using '--network none' and so of
course there is no network connectivity inside the guest. My own
attempts at fixing this were unsuccessful, in that I can get a PCI
device such as rtl8139 or even virtio-net-pci to be detected by the
guest, but the corresponding drivers are not included in the kernel
downloaded from the GitHub repository linked above; the versatilepb
board's own integrated network device (smc91c111), on the other hand,
seems not to support instantiation via -device and is thus not usable
without adding hacks to libvirt. Did you manage to get network
functionality working some other way?
Since you already need a custom kernel to boot the image with QEMU,
and you also use an approximation of the actual hardware rather than
a faithful reproduction, I think it would make sense to go one step
further and include VirtIO drivers in the kernel image.
