assuming stable building -current
We want to keep the tools there – no need to rebuild them each time
find sys/arch/amd64/conf/ time ./build.sh -T /root/tools -O /root/obj -j 16 tools time ./build.sh -T /root/tools -O /root/obj -j 16 kernel=XEN3_DOMU

Make sure you have enough RAM (at least 2GB I would say, but 8GB is probably preferable), and eventually increase the number of vcpus.

shutdown -p now
and change its settings to point to the new kernel,
kernel = "/data/kernels/netbsd8/altqnpf"
At system startup, watch the console and check,
dmesg | grep ^NetBSD uname -a

==> either use config -s or put your sources folder in the default location (/usr/src)
