"This is the first time we've been able to offer our open source OS virtualization in this format, which provides users a risk-free way to test OpenVZ, along with the Knoppix distribution," said Kir Kolyshkin, the OpenVZ project's manager, in a statement. "Knoppix is very popular with hobbyists and Linux enthusiasts who can now try our open-source virtualization software, which is in keeping with our objective to promote OS virtualization."
