Bhyve on FreeBSD 10.1

I recently started a new series of videos on YouTube about my favorite operating system FreeBSD. Below are the commands used in the video to setup the bhyve hypervisor on FreeBSD 10.1 with a virtualized Ubuntu 15 server.

 

######## prerequisites for bhyve on FreeBSD ##########
pkg install grub2-bhyve
mkdir /virtual_machines
cd /virtual_machines
mkdir iso
cd iso
fetch http://releases.ubuntu.com/15.04/ubuntu-15.04-server-amd64.iso

######    Load kernel modules and set sysctl values ######
kldload if_tap
kldload if_bridge
kldload vmm
kldload nmdm
###### set sysctl values  #######3
sysctl net.link.tap.up_on_open=1
sysctl net.inet.ip.forwarding=1
echo “net.link.tap.up_on_open=1” >> /etc/sysctl.conf
echo “vm1:dv=/dev/nmdm1B:br#9600:pa=none:” >> /etc/remote
##### create interfaces needed for the vm  ########

ifconfig tap1 create
ifconfig bridge0 create
ifconfig bridge0 addm tap1 addm em0 up
