Hello all, In ubuntu 13.10 libguestfs version 1:1.22.4-1 seems broken. I don't seem to be able to create a working appliance. After installing libguestfs-tools and executing "sudo libguestfs-test-tool" I get: 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. The complete output of the command can be found in the attached file. I did report this to Ubuntu (https://bugs.launchpad.net/ubuntu/+source/libguestfs/+bug/1243190) but I thought you might want to take a look at this too. Kind regards, Nikos Skalkotos
