[Libguestfs] Cubietruck: QEMU, KVM and Fedora

[Thomas Kee]

Hi Kashyap, Richard,

Before I moved on to new things I wanted to let you know that it took a
bit of package finesse and some time, but I was able to use the git repo
make it through
libguestfs-test-tool without issue on this platform:

Linux cubietruck 4.3.0-1-armmp-lpae #1 SMP Debian 4.3.5-1 (2016-02-06)
armv7l GNU/Linux

The log is attached.  I now have bigger brain about arm-kvm thanks to
your help.

Cheers,

Thomas
