-Two RPMs will be output into /usr/src/redhat/RPMS, whose names begin
-with "vswitch" and "vswitch-debuginfo".
+ <Xen Kernel version> is the output of:
+ rpm -q --queryformat "%{Version}-%{Release}" kernel.*xen-devel
+ e.g. 2.6.32.12-0.7.1.xs5.6.100.323.170596
+
+ <Xen Kernel flavor (suffix) > is either "xen" or "kdump".
+ The "xen" flavor is the main running kernel flavor and the "kdump" flavor is
+ the crashdump kernel flavor. Commonly, one would specify "xen" here.
+
+Three RPMs will be output into /usr/src/redhat/RPMS/i386, whose names begin
+with "openvswitch", "openvswitch-modules-xen" (if building for kernel_flavor=xen),
+and "openvswitch-debuginfo".
