curl http://netbsd.org/~kamil/patch-00074-permit-fpudna-in-kernel.txt | patch -p0

# III. [deleted step]

# IV. Build the iso
# 1. build distribution

./build.sh -U -u -j8 -m amd64 -N0 distribution

# 2. build release
./build.sh -U -u -j8 -m amd64 -N0 release

# 3. build iso-image
./build.sh -U -u -j8 -m amd64 -N0 iso-image

# V. Locate iso and install it (select all sets)

NetBSD-8.99.*-amd64.iso

# VI. Prepare pkgsrc

ftp -o- ftp://ftp.netbsd.org/pub/pkgsrc/stable/pkgsrc.tar.gz | tar -zxpf- -C /usr
cd /usr/pkgsrc/devel/git-base && make install
cd /usr/pkgsrc/security/mozilla-rootcerts && make install
# And follow the MESSAGE commands to finish the installation.

# VII. Prepare pkgsrc-wip

cd /usr/pkgsrc
git clone --depth 1 git://wip.pkgsrc.org/pkgsrc-wip.git wip
cd /usr/pkgsrc/wip/qemu-haxm
make install

# VIII. Fetch and build haxm

git clone https://github.com/intel/haxm
cd platforms/netbsd
make

# IX. Insert haxm into the kernel

modload ./haxm.kmod

# check kernel log with:

dmesg|tail

# X. Create HAXM devices

mknod /dev/HAX c 220 0
mkdir /dev/hax_vm
for i in `seq 0 7`; do mkdir /dev/hax_vm0$i; done
for i in `seq 0 7`; do mknod /dev/hax_vm/vm0$i c 222 $i; done

# Use the following script to create vcpu nodes
#!/bin/sh
i=0
while [ $i -lt 128 ]; do
        vm=$(echo "$i/16"|bc)
        vcpu=$(echo "$i%16"|bc)
        echo "i=$i vm=$vm vcpu=$vcpu"
        cmd=$(printf "mknod /dev/hax_vm%02d/vcpu%02d c 221 %d" $vm $vcpu $i)
        $cmd
        let "i+=1"
done

# XI. Run qemu
