Xen runs on RHEL6 & CentOS6. RedHat does not support this, but Xen still strives to run on RHEL6.

See http://wiki.xen.org/xenwiki/RHEL6Xen4Tutorial for a tutorial and a list of required RPMs. This tutorial says:

As a default RHEL6 does NOT:

  • RHEL6 does not ship Xen hypervisor or tools.
  • RHEL6 does not ship Xen dom0 capable kernel.

As a default RHEL6 DOES:

  • RHEL6 runs as Xen PV (paravirtual) domU using the pvops framework in the default kernel.
  • RHEL6 runs as Xen HVM (fully virtualized) guest.
  • RHEL6 ships with optimized Xen PV-on-HVM drivers for RHEL6 Xen HVM guests.
