This also enabled me to build infrastructure with code and made creating test environments repeatable and consistent. * I automated the installation and configuration of DNS, DHCP, PXE and other infrastructure systems to bring a base physical Ubuntu system into a KVM Hypervisor running virtual machines with Vdbench, testing filesystems against a SolidFire cluster in under 15 minutes.
