install and alpine virt 3.7 in xhyve

1. run latest alpine in the xhyve

1. install the xhyve
   follow the instruction to install the xhyve from xhyve.org
   or brew install —HEAD xhyve

1. download the alpine from the alpinelinux.org
   you may find the your fast mirrors near you, I prefer the virt version of the image.

curl -LO http://dl-3.alpinelinux.org/alpine/v3.7/releases/x86_64/alpine-virt-3.7.0-x86_64.iso

1. extract the kernel from the images
   extract kernel and initramfs
   brew install cdrtools
   isoinfo -i alpine-virt-3.7.0-x86_64.iso -J -x /boot/initramfs-* > initramfs
   isoinfo -i alpine-virt-3.7.0-x86_64.iso -J -x /boot/vmlinuz-* > vmlinuz

1. boot to install
   sudo install.sh
   login as root
   prepare the harddisk
   setup-alpine
   follow the install process
   finish…
   And hold on,
   we need grap the uuid from the environment

`mkdir /mnt/vda1
`mount -t ext4 /dev/vda1 /mnt/vda1

`cat /mnt/vda1/extlinux.conf | grep APPEND
`# e.g. result:
`# APPEND root=UUID=19023208-f0f5-4c34-b27c-9f011ba78c5e modules=sd-mod,usb-storage,ext4 quiet
halt

1. replace {UUID} in run.sh with UUID from above

`sudo ./run.sh

1. the install.sh script

#!/bin/sh

1. Linux
   KERNEL=“vmlinuz”
   INITRD=“initramfs”
   CMDLINE=“modules=sd-mod,ext4,console quiet console=ttyS0”

IMG_CD=“-s 3,ahci-cd,alpine.iso”
IMG_HDD=“-s 4,virtio-blk,hdd.img”
PCI_DEV=“-s 0:0,hostbridge -s 31,lpc”
LPC_DEV=“-l com1,stdio”

1. UUID=“-U deadbeef-dead-dead-dead-deaddeafbeef”

1. Linux
   xhyve $ACPI $MEM $SMP $PCI_DEV $LPC_DEV $NET $IMG_CD $IMG_HDD $UUID -f kexec,$KERNEL,$INITRD,“$CMDLINE”

and the run.sh
UUID was grap from the installed boot configuration.

#!/bin/bash

INITRD=“initramfs”
