 FWIW, the problem can be reproduced independent of the Linux version: my provider uses Linux 4.4.X/Qemu 2.5, and I can reproduce it on a Ubuntu 17.04 (Linux 4.10.X/Qemu 2.8) machine as follows:
 
 $ qemu-img create nbsd.img 10G
 $ qemu-system-x86_64 -drive if=none,id=hd,file=nbsd.img,format=raw -device virtio-scsi-pci,id=scsi --enable-kvm -device scsi-hd,drive=hd -cdrom NetBSD-7.99.70-amd64.iso 
 # for scsi-layer tracing add -d trace:*scsi*
 
 the sysinst installation stalls and the "adapter resource shortage" messages appear.
