-Q: What Linux kernel versions does IPFIX flow monitoring work with?
+Q: I get an error like this when I configure Open vSwitch:
-A: IPFIX flow monitoring requires the Linux kernel module from Open
- vSwitch version 1.10.90 or later.

-Q: Should userspace or kernel be upgraded first to minimize downtime?
+ What should I do?
- In general, the Open vSwitch userspace should be used with the
- kernel version included in the same release or with the version
- from upstream Linux. However, when upgrading between two releases
- of Open vSwitch it is best to migrate userspace first to reduce
- the possibility of incompatibilities.
+A: If there is a newer version of Open vSwitch, consider building that
+ one, because it may support the kernel that you are building
+ against. (To find out, consult the table in the previous answer.)

+ Otherwise, use the Linux kernel module supplied with the kernel
+ that you are using. All versions of Open vSwitch userspace are
+ compatible with all versions of the Open vSwitch kernel module, so
+ this will also work. See also the following question.
