+# Creating a New FreeBSD VM Guest on Ganeti
+
+## Create the Guest VM
+
+Use the silly script ~root/do-add
+
+```
+./do-add vm0 100 2 work0.psg.com
+```
+
+Which looks like
+
+```
+#!/bin/sh
+
+# makeVM node diskGB ramGB nameFQDN
+
+NODE=$1
+DISK=$2
+RAM=$3
+NAME=$4
+
+gnt-instance add \
+     -t plain \
+     -o noop \
+     -s ${DISK}G \
+     -B maxmem=${RAM}G,minmem=$((${RAM}/2))G \
+     -n $NODE \
+     -H kvm:vnc_bind_address=0.0.0.0 \
+     --no-install \
+     --no-start \
+     --no-ip-check \
+     --no-name-check \
+     ${NAME}
+```
+
+## Start the Guest VM With the CD-ROM Mounted
+
+You should get the latest and greatest ISO of the opsys you wish to  install and put in in /ISOs on the node to which you are installing.   And then
+
+```
+gnt-instance start -H boot_order=cdrom,cdrom_image_path=/ISOs/FreeBSD-10.0-STABLE-i386-20140712-r268571-disc1.iso work0.psg.com
+```
+
+## Find the Console Port of the Running VM
+
+```
+gnt-instance info work0.psg.com | grep console
+```
+
+Which will produce something similar to
+
+```
+  console connection: vnc to vm1.sea.rg.net:11024 (display 5124)
+    serial_console: default (True)
+```
+
+You are interested in the 11024, not the 5124.
+
+## Tunnel VNC over SSH
+
+From your laptop
+
+```
+ssh -N -L 5900:127.0.0.1:<port from gnt-instance info> <vm node>
+```
+
+Of course you will need an account on the vm node
+
+## Run VNC to the Guest VM
+
+From your laptop, use a VNC client to connect to localhost, display 0, password as set for the VM host.
+
+## Do the Install
+
+It should have booted the CD-ROM.  Now do the install of the OpSys in your usual fashion.
+
+When it finishes, if you just let it reboot, it will likely just boot the CD-ROM again.  So restart the guest by
+
+```
+gnt-instance reboot work0.psg.com
+```
+
+## DRBD Mirror Guest to CLuster
+
+You will likely want the reliability of mirroring the guest to another node in the cluster.  I have a script I use
+
+```
+#!/bin/sh
+# do-drbd guest-name to-node
+gnt-instance shutdown $1
+gnt-instance modify \
+    -t drbd \
+    --no-wait-for-sync \
+    -n $2 \
+    $1
+gnt-instance start $1
+```
