[I did not find vmchannel support in $QEMU.

vmchannel support is vital for libguestfs to operate.  You need a version
of qemu >= 0.10, or the following patch backported to earlier versions:

http://lists.gnu.org/archive/html/qemu-devel/2009-02/msg01042.html

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
and install it in another location, then you should configure with
the --with-qemu option.
