Virtualization Support in Red Hat Enterprise Linux

Red Hat Enterprise Linux Virtualization Support Matrix

1. Please see chart below for details.
2. Please note that running in a virtualized environment may be subject to the third party operating systems license agreement.

Legend
PV	Para-Virtualized (Xen): Guest kernel optimized for virtualization.
FV	Fully-Virtualized (Xen or KVM): Unmodified guest kernel, requires virtualization support in hardware.
Optimized	Supported. PV or optimized PV drivers provided, fully certified stack (e.g. Microsoft SVVP).
Supported	Supported but no or limited optimized PV drivers provided, limited certification (for Windows Server e.g. Microsoft WHQL but no SVVP).
Unsupported	Not supported and may not work
N/A	Not a valid combination.
Tech Preview	Technically possible, but not yet supported.
