Don't gzip the kernel, here's an example session:

$ git branch
* perf
$ ./build.sh -U -u -j4 -T obj/tooldir -m amd64 tools
$ ./build.sh -U -u -j4 -T obj/tooldir -m amd64 kernel=MICROVM
$ KERNEL=sys/arch/amd64/compile/obj/MICROVM/netbsd
$ IMG=NetBSD-10.99.10-amd64-live.img # fetch and gunzip this from 
https://nycdn.netbsd.org/pub/NetBSD-daily/HEAD/202403200640Z/images/NetBSD-10.99.
10-amd64-live.img.gz
$ qemu-system-x86_64 \
        -M microvm,x-option-roms=off,rtc=on,acpi=off,pic=off \
        -enable-kvm -m 512 -cpu host,+invtsc \
        -append "root=ld0a console=com rw -v" -display none \
        -device virtio-blk-device,drive=hd0 \
        -drive file=${IMG},format=raw,id=hd0 \
        -netdev user,id=net0,hostfwd=tcp::10022-:22 \
        -device virtio-net-device,netdev=net0 \
        -kernel ${KERNEL} -serial mon:stdio

FYI I'll be mostly AFK till next Tuesday.

Cheers,
