CentOS 6 and iohyve

This page is outdated and only should be used for archive purposes. Please see the README for up to date info on how to run CentOS under iohyve.

Try out CentOS 6:

iohyve set centguest loader=grub-bhyve
iohyve set centguest os=centos6
iohyve set centguest ram=512M			# CentOS6 Requirement
iohyve install centguest CentOS-6.7-x86_64-netinstall.iso

# Okay whoa, hold on, we can go two ways here. 
# There the hacky way, and the more hacky way. 
# Option 1: Update a property everytime the kernel is updated. 
# Option 2: Do some things, compile things, not worry so much. 

# Option 1:
iohyve set centguest os=custom 			# Do this once
iohyve set centguest autogrub='linux%1s(hd0,msdos1)/vmlinuz-2.6.32-573.el6.x86_64%1sroot=/dev/mapper/VolGroup-lv_root\ninitrd%1s(hd0,msdos1)/initramfs-2.6.32-573.el6.x86_64.img\nboot\n'
# I know, right? Do that everytime you update your Linus kernel. 

# Option 2:
iohyve set centguest os=default
iohyve start centguest				# Do some things
iohyve console centos guest			

# Find the kernel and things to boot the first time.
