"According to Red Hat, the plan is to have a Linux version ready by some point in 2010. But in the meantime, Red Hat customers who want to run the virtualization manager must purchase or already own a Windows server.
""The Windows Server could be running as a virtual server in RHEL (Red Hat Enterprise Linux), but you would require a Windows machine for the management system," Andy Cathrow, product marketing manager for Red Hat Enterprise Virtualization, told InternetNews.com. "We spent a lot of time talking to customers to see what their view was on this and I think with the possible exception of Red Hat, everyone has some Windows in their datacenter.""
