I don't know rackspace's service, but if its xen or kvm in HVM mfsbsd is
proabably the way to go.
I just tested with a centos6 vm on a KVM hypervisor.
wget -O /boot/mfsbsd.iso http://mfsbsd.vx.sk/iso/mfsbsd-8.2-zfsv28-amd64.iso
yum -y install syslinux
cp /usr/share/syslinux/memdisk /boot

add the following to the bottom of /boot/grub/grub.conf
title fbsd
        root (hd0,0)
        kernel /memdisk iso
        initrd /mfsbsd.iso

and make that the active entry in grub, and voila a freebsd system
running from a memory disk, with DHCP and sshd allowing a root login to
do what you want with the host system. As i said, I can confirm that
works on a Centos5 KVM hypervisor if starting from a centos6 VM, I
havent tested further.

The downside is that its DHCP not a static IP (I assume you can
recompile the mfsbsd image to do what you want it to.) and as I dont use
grub much i dont know if you can set the mfsbsd iso to be a one time
boot in case of issues.

you could also try

dont know if that still works.
