minimize downtime?
Q: What features are not available in the Open vSwitch kernel datapath
that ships as part of the upstream Linux kernel?
-A: The kernel module in upstream Linux 3.3 and later does not include
- tunnel virtual ports, that is, interfaces with type "gre",
- "ipsec_gre", "gre64", "ipsec_gre64", "vxlan", or "lisp". It is
- possible to create tunnels in Linux and attach them to Open vSwitch
- as system devices. However, they cannot be dynamically created
- through the OVSDB protocol or set the tunnel ids as a flow action.
-
- Work is in progress in adding tunnel virtual ports to the upstream
- Linux version of the Open vSwitch kernel module. For now, if you
- need these features, use the kernel module from the Open vSwitch
+A: The kernel module in upstream Linux does not include support for

distribution instead of the upstream Linux kernel module.
- The upstream kernel module does not include patch ports, but this
- only matters for Open vSwitch 1.9 and earlier, because Open vSwitch
- 1.10 and later implement patch ports without using this kernel
- feature.
+ Certain features require kernel support to function or to have

+ a feature is not supported, consider upgrading to a newer upstream
+ Linux release or using the kernel module paired with the userspace
+ distribution.
