Oh that is great, I'll drop the vhost-vsock-pci device then. I thought
adding it fixed the error I was getting when trying to use
VMADDR_CID_LOCAL, but it must have just been adding
CONFIG_VSOCKETS_LOOPBACK that fixed it.

Wait, IIUC we only use loopback, so why do we need to attach the
vhost-vsock-pci device to QEMU?
At that point if we add CONFIG_VSOCKETS_LOOPBACK in all configurations,
it should also work with aarch64 and s390x.
Thanks,
Stefano
