-vmchannel support is vital for libguestfs to operate.  You need a version
-of qemu >= 0.10, or the following patch backported to earlier versions:
+    if test "x$vmchannel_net_user" = "xno" -a "x$vmchannel_guestfwd" = "xno"; then
+        AC_MSG_FAILURE(
+[I did not find user mode network or vmchannel support in
+$QEMU.
 
-http://lists.gnu.org/archive/html/qemu-devel/2009-02/msg01042.html
+Either user mode networking or vmchannel support is vital for
+libguestfs to operate.
+
+Please read the relevant section in the README file for more
+information about this.
 
 You can override this test by setting the environment variable
-vmchannel_test=no  However if you don't have vmchannel support
+vmchannel_test=no  However if you don't have the right support
 in your qemu, then this just delays the pain.
 
 If I am using the wrong qemu or you want to compile qemu from source
 and install it in another location, then you should configure with
 the --with-qemu option.
