+vmchannel support is vital for libguestfs to operate.  You need a version

+You can override this test by setting the environment variable
+vmchannel_test=no  However if you don't have vmchannel 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
