freebsd on rackspace

[Aryeh Friedman-2]

I just talked to rackspace tech support on an other issue and they
said they plan to offer FreeBSD as a option after the upgrade from
Zend Classic to Zend Enterprise (ETA not known).... but they did say
we as a client are free to overwrite any slice on the virtual disk and
then use the console to configure GRUB to boot that kernel... any
ideas on how to proceed from this general advice to an actual
implementation? ..... they also said if we did get it to work before
the Zend upgrade was complete they would use our solution as the
standard one

Colin Percival has done some work to get FreeBSD running on EC2:

http://www.daemonology.net/freebsd-on-ec2/

that might be a good start for some pointers.

Cheers,

Tony

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.
