Hi there, I am trying to write an article on virt-builder and managed to compile version 1.24.1 of libguestfs on Ubuntu 13.10 (I had mixed success with the git version and 1.25.x). When I am running virt-builder I am getting an error message: virt-builder: error: virt-resize failed Upon further investigation it turns out that there's a kernel panic when booting the freshly created image. Running the test-tool gives the following output: -------------------------------------------------------------------- LIBGUESTFS_PATH=/home/ofrommel/libguestfs-1.24.1/appliance LIBGUESTFS_CACHEDIR=/home/ofrommel/libguestfs-1.24.1/tmp LD_LIBRARY_PATH=/home/ofrommel/libguestfs-1.24.1/ruby/ext/guestfs:/home/ofrommel/libguestfs-1.24.1/src/.libs:/home/ofrommel/libguestfs-1.24.1/gobject/.libs LIBGUESTFS_TMPDIR=/home/ofrommel/libguestfs-1.24.1/tmp PATH=/home/ofrommel/libguestfs-1.24.1/align:/home/ofrommel/libguestfs-1.24.1/builder:/home/ofrommel/libguestfs-1.24.1/cat:/home/ofrommel/libguestfs-1.24.1/df:/home/ofrommel/libguestfs-1.24.1/edit:/home/ofrommel/libguestfs-1.24.1/erlang:/home/ofrommel/libguestfs-1.24.1/fish:/home/ofrommel/libguestfs-1.24.1/format:/home/ofrommel/libguestfs-1.24.1/fuse:/home/ofrommel/libguestfs-1.24.1/rescue:/home/ofrommel/libguestfs-1.24.1/resize:/home/ofrommel/libguestfs-1.24.1/sparsify:/home/ofrommel/libguestfs-1.24.1/sysprep:/home/ofrommel/libguestfs-1.24.1/test-tool:/home/ofrommel/libguestfs-1.24.1/tools:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games SELinux: sh: 1: getenforce: not found library version: 1.24.1 guestfs_get_append: (null) guestfs_get_backend: direct guestfs_get_autosync: 1 guestfs_get_cachedir: /home/ofrommel/libguestfs-1.24.1/tmp guestfs_get_direct: 0 guestfs_get_hv: /usr/bin/kvm guestfs_get_memsize: 500 guestfs_get_network: 0 guestfs_get_path: /home/ofrommel/libguestfs-1.24.1/appliance guestfs_get_pgroup: 0 guestfs_get_program: libguestfs-test-tool guestfs_get_recovery_proc: 1 guestfs_get_selinux: 0 guestfs_get_smp: 1 guestfs_get_tmpdir: /home/ofrommel/libguestfs-1.24.1/tmp guestfs_get_trace: 0 guestfs_get_verbose: 1 host_cpu: x86_64 Launching appliance, timeout set to 600 seconds. libguestfs: launch: backend registered: unix libguestfs: launch: backend registered: uml libguestfs: launch: backend registered: libvirt libguestfs: launch: backend registered: direct libguestfs: launch: backend=direct libguestfs: launch: tmpdir=/home/ofrommel/libguestfs-1.24.1/tmp/libguestfsC8azDe libguestfs: launch: umask=0002 libguestfs: launch: euid=1001 libguestfs: command: run: /usr/bin/supermin-helper libguestfs: command: run: \ --verbose libguestfs: command: run: \ -f checksum libguestfs: command: run: \ /home/ofrommel/libguestfs-1.24.1/appliance/supermin.d libguestfs: command: run: \ x86_64 supermin helper [00000ms] whitelist = (not specified), host_cpu = x86_64, kernel = (null), initrd = (null), appliance = (null) supermin helper [00000ms] inputs[0] = /home/ofrommel/libguestfs-1.24.1/appliance/supermin.d checking modpath /lib/modules/3.11.0-12-generic is a directory picked vmlinuz-3.11.0-12-generic because modpath /lib/modules/3.11.0-12-generic exists checking modpath /lib/modules/3.8.0-31-generic is a directory picked vmlinuz-3.8.0-31-generic because modpath /lib/modules/3.8.0-31-generic exists supermin helper [00000ms] finished creating kernel supermin helper [00000ms] visiting /home/ofrommel/libguestfs-1.24.1/appliance/supermin.d supermin helper [00000ms] visiting /home/ofrommel/libguestfs-1.24.1/appliance/supermin.d/base.img supermin helper [00000ms] visiting /home/ofrommel/libguestfs-1.24.1/appliance/supermin.d/daemon.img supermin helper [00000ms] visiting /home/ofrommel/libguestfs-1.24.1/appliance/supermin.d/hostfiles supermin helper [00040ms] visiting /home/ofrommel/libguestfs-1.24.1/appliance/supermin.d/init.img supermin helper [00040ms] visiting /home/ofrommel/libguestfs-1.24.1/appliance/supermin.d/udev-rules.img supermin helper [00040ms] adding kernel modules supermin helper [00112ms] finished creating appliance libguestfs: checksum of existing appliance: 82bc0831de24ca2bd6a023ee99ee9d9351f4ea2cbc00a96791e7060658ed7a64 libguestfs: [00115ms] begin testing qemu features libguestfs: command: run: /usr/bin/kvm libguestfs: command: run: \ -nographic libguestfs: command: run: \ -help W: kvm binary is deprecated, please use qemu-system-x86_64 instead libguestfs: command: run: /usr/bin/kvm libguestfs: command: run: \ -nographic libguestfs: command: run: \ -version W: kvm binary is deprecated, please use qemu-system-x86_64 instead libguestfs: qemu version 1.5 libguestfs: command: run: /usr/bin/kvm libguestfs: command: run: \ -nographic libguestfs: command: run: \ -machine accel=kvm:tcg libguestfs: command: run: \ -device ?

Is there a way to stop libguestfs tools from doing that? BTW: the tools *do* require root access when running on Ubuntu because it (the distro) has the kernel images readable only for root. I understand that this is not libguestfs's fault, just sayin'... Thanks for any help. Best Oliver
