Loading the amd patched KVM on SmartOS at boot

From https://gist.github.com/jclulow/2cb28f48a01b56c01153

mkdir -p /opt/custom/{smf,bin,kvm} &&
curl -kL https://raw.github.com/gist/2cb28f48a01b56c01153/postboot \
   > /opt/custom/bin/postboot &&
chmod 755 /opt/custom/bin/postboot &&
curl -kL https://raw.github.com/gist/2cb28f48a01b56c01153/postboot.xml \
   > /opt/custom/smf/postboot.xml &&
cd /opt/custom/kvm &&
curl -kL https://jmc.sysmgr.org/downloads/kvm-ec85cf5f7.tar.gz | tar xvfz - &&
svccfg import /opt/custom/smf/postboot.xml

jclulow uses this method to mount the kvm binary from the tarball over the system-provided binary and load the module at boot.


Saving the files since the links have been changed on github. Also that kernel version is no longer available at that url. So will have to self host to use in future.

postboot

	#!/bin/ksh
	[[ -f /var/run/.postboot ]] && {
	echo "postboot already run"
	exit 0
	}
	mount -F lofs -o ro \
	/opt/custom/kvm/kvm \
	/usr/kernel/drv/amd64/kvm &&
	update_drv kvm
	touch /var/run/.postboot
