Freedom and Justice are two twin KVM hosts bought by Sugar Labs in 2012.

Justice is currently our primary VM hosting box, while freedom is a hot-standby with secondary services and backups.


  • 2U rack-mountable case
  • Motherboard ASUS KFSN5-D
  • 8-core Opteron 6212 @ 1.4GHz
  • 64GB RAM
  • 2x1TB RAID1


  • Ubuntu Precise (12.04) amd64 on justice
  • Ubuntu 14.04 LTS on freedom


Hosted by the MIT Media Lab, building E15.


Network configuration

Justice is globally accessible through public, static IPv4. The IPv6 /64 subnet (6to4) is currently experimental and not associated with AAAA records.

IPs are available for hosted VMs.

Hosted VMs

All KVM virtual machines are managed by libvirtd. Yes, that's scary.

See Sysadmin/Add virtual machine for creating new VMs.
