XenSource is the company behind the open source Xen hypervisor. Founded by the creators of Xen, XenSource is focused on delivery of the world's best virtualization software.. Xen is included in FC5, OpenSUSE, and will be RHEL 5 and SLES 10. Xen is supported in OpenSolaris, and supports fully virtualized OSes (Windows, legacy Linux) using Intel(r) VT and AMD(r)-V hardware virtualization technologies. The XenSource GSC projects will develop components for the OSS Xen hypervisor, which will (subject to open source acceptance) be added to the Xen code base. Xen is undeniably the hottest open source project right now, and we are somewhat swamped by high quality candidates. We need 'deep systems' skill sets - folks who are happiest down at the lowest levels of the OS, and who know the x86 architecture inside and out.
