... the kernel boots quite far, and then hangs in the init script (see appliance/init). Some things you can try: - Force qemu to use TCG (no KVM) mode to see if that makes a difference: export LIBGUESTFS_BACKEND_SETTINGS=force_tcg - Use 'libguestfs-test-tool' for testing to see if that makes a difference. In the build directory, run: make quickcheck - Try a different appliance kernel by setting these variables, but choose different kernel versions by looking in your /boot directory first: export SUPERMIN_KERNEL_VERSION=3.13.0-55-generic export SUPERMIN_KERNEL=/boot/vmlinuz-$SUPERMIN_KERNEL_VERSION export SUPERMIN_MODULES=/lib/modules/$SUPERMIN_KERNEL_VERSION rm -rf tmp/.guestfs-* make quickcheck - Add debugging 'set -x' to the top of appliance/init in the source tree to see if it fails while running a specific command.
