Almost certainly kernel version <= 2.6.34-ish (whichever version it
was that added virtio-serial support, definitely 2.6.32 does NOT work
and 2.6.36 DOES work).
I'd be able to tell for sure if I saw the complete output.
I see. Yeah, we're stuck at 2.6.32. Compelte output:

Failed to connect to virtio-serial channel.
This is a fatal error and the appliance will now exit.
Usually this error is caused by either QEMU or the appliance
kernel not supporting the vmchannel method that the
libguestfs library chose to use. Please run
'libguestfs-test-tool' and provide the complete, unedited
output to the libguestfs developers, either in a bug report
or on the libguestfs redhat com mailing list.
