Re: [Libguestfs] appliance VM won't start, can't find /init, but /init is in the image.

I can confirm the /var/tmp/.guestfs has a root file that is a valid ext2 file system. libguestfs: new guestfs handle 0x22df410 ===== Test starts here ===== LIBGUESTFS_DEBUG=1 library version: 1.12.3 guestfs_get_append: (null) guestfs_get_attach_method: appliance guestfs_get_autosync: 1 guestfs_get_direct: 0 guestfs_get_memsize: 500 guestfs_get_network: 0 guestfs_get_path: /usr/local/home/dek/sw/libguestfs-1.12.3/lib/guestfs guestfs_get_pgroup: 0 guestfs_get_qemu: /home/dek/sw/qemu-kvm-0.14.1/bin/qemu-system-x86_64 guestfs_get_recovery_proc: 1 guestfs_get_selinux: 0 guestfs_get_trace: 0 guestfs_get_verbose: 1 host_cpu: x86_64 Launching appliance, timeout set to 120 seconds. libguestfs: [00000ms] febootstrap-supermin-helper --verbose -f checksum '/usr/local/home/dek/sw/libguestfs-1.12.3/lib/guestfs/supermin.d' x86_64 supermin helper [00000ms] whitelist = (not specified), host_cpu = x86_64, kernel = (null), initrd = (null), appliance = (null) supermin helper [00000ms] inputs[0] = /usr/local/home/dek/sw/libguestfs-1.12.3/lib/guestfs/supermin.d checking modpath /lib/modules/2.6.32-gg508-generic.disabled is a directory picked vmlinuz-2.6.32-gg508-generic.disabled because modpath /lib/modules/2.6.32-gg508-generic.disabled exists checking modpath /lib/modules/2.6.38.8-experimental4 is a directory picked vmlinuz-2.6.38.8-experimental4 because modpath /lib/modules/2.6.38.8-experimental4 exists supermin helper [00000ms] finished creating kernel supermin helper [00000ms] visiting /usr/local/home/dek/sw/libguestfs-1.12.3/lib/guestfs/supermin.d supermin helper [00000ms] visiting /usr/local/home/dek/sw/libguestfs-1.12.3/lib/guestfs/supermin.d/base.img supermin helper [00000ms] visiting /usr/local/home/dek/sw/libguestfs-1.12.3/lib/guestfs/supermin.d/daemon.img supermin helper [00000ms] visiting /usr/local/home/dek/sw/libguestfs-1.12.3/lib/guestfs/supermin.d/hostfiles supermin helper [00016ms] visiting /usr/local/home/dek/sw/libguestfs-1.12.3/lib/guestfs/supermin.d/init.img supermin helper [00049ms] finished creating appliance libguestfs: [00053ms] begin testing qemu features libguestfs: [00065ms] finished testing qemu features libguestfs: accept_from_daemon: 0x22df410 g->state = 1 libguestfs: [00066ms] /home/dek/sw/qemu-kvm-0.14.1/bin/qemu-system-x86_64 \ -drive file=/tmp/libguestfs-test-tool-sda-iWMYOJ,cache=off,format=raw,if=virtio \ -nodefconfig \ -enable-kvm \ -nodefaults \ -nographic \ -m 500 \ -no-reboot \ -no-hpet \ -device virtio-serial \ -serial stdio \ -chardev socket,path=/tmp/libguestfsMqHmAh/guestfsd.sock,id=channel0 \ -device virtserialport,chardev=channel0,name=org.libguestfs.channel.0 \ -kernel /var/tmp/.guestfs-88619/kernel.23376 \ -initrd /var/tmp/.guestfs-88619/initrd.23376 \ -append 'panic=1 console=ttyS0 udevtimeout=300 noapic acpi=off printk.time=1 cgroup_disable=memory selinux=0 guestfs_verbose=1 TERM=rxvt ' \ -drive file=/var/tmp/.guestfs-88619/root.23376,snapshot=on,if=virtio,cache=unsafe [ 0.000000] Initializing cgroup subsys cpuset [ 0.000000] Linux version 2.6.38.8-experimental4 (root(a)redacted.com) (gcc version 4.4.3 (Ubuntu 4.4.3-4ubuntu5) ) #2 SMP Mon Jun 27 14:14:51 PDT 2011 [ 0.000000] Command line: panic=1 console=ttyS0 udevtimeout=300 noapic acpi=off printk.time=1 cgroup_disable=memory selinux=0 guestfs_verbose=1 TERM=rxvt [ 0.000000] BIOS-provided physical RAM map: [ 0.000000] BIOS-e820: 0000000000000000 - 000000000009bc00 (usable) [ 0.000000] BIOS-e820: 000000000009bc00 - 00000000000a0000 (reserved) [ 0.000000] BIOS-e820: 00000000000f0000 - 0000000000100000 (reserved) [ 0.000000] BIOS-e820: 0000000000100000 - 000000001f3fd000 (usable) [ 0.000000] BIOS-e820: 000000001f3fd000 - 000000001f400000 (reserved) [ 0.000000] BIOS-e820: 00000000feffc000 - 00000000ff000000 (reserved) [ 0.000000] BIOS-e820: 00000000fffc0000 - 0000000100000000 (reserved) [ 0.000000] NX (Execute Disable) protection: active [ 0.000000] DMI 2.4 present.
