Hello everyone, I have a corrupt .vdi file from a virtualbox installation (XP host, Mint 11 guest) which I recently broke. I wanted to allocate more space to it, so I ran this command:VBoxManage.exe modifyhd /path/to/YOUR_HARD_DISK.vdi --resize 17179869184 It only took a second to actually complete, so I think a header somewhere is broken. I need to get access to some files I had on there using libguestfs on a Mint Virtualbox I have, and I'm trying to mount the bad vdi file to get access to everything, but that isn't working. I have this output from libguestfs-test-tool, can anyone help?:Thanks! libguestfs: new guestfs handle 0x10242d0libguestfs: [00000ms] febootstrap-supermin-helper --verbose -f checksum '/usr/lib/guestfs/supermin.d' x86_64supermin helper [00000ms] whitelist = (not specified), host_cpu = x86_64, kernel = (null), initrd = (null), appliance = (null)supermin helper [00001ms] inputs[0] = /usr/lib/guestfs/supermin.dchecking modpath /lib/modules/2.6.38-8-generic is a directorypicked vmlinuz-2.6.38-8-generic because modpath /lib/modules/2.6.38-8-generic existssupermin helper [00001ms] finished creating kernelsupermin helper [00002ms] visiting /usr/lib/guestfs/supermin.dsupermin helper [00002ms] visiting /usr/lib/guestfs/supermin.d/base.imgsupermin helper [00007ms] visiting /usr/lib/guestfs/supermin.d/daemon.imgsupermin helper [00007ms] visiting /usr/lib/guestfs/supermin.d/hostfilessupermin helper [00142ms] visiting /usr/lib/guestfs/supermin.d/init.imgsupermin helper [00142ms] adding kernel modulessupermin helper [00341ms] finished creating appliancelibguestfs: [00373ms] begin testing qemu featureslibguestfs: [00551ms] finished testing qemu featureslibguestfs: accept_from_daemon: 0x10242d0 g->state = 1libguestfs: is_openable: /dev/kvm: No such file or directory[00563ms] /usr/bin/kvm \ -drive file=/tmp/libguestfs-test-tool-sda-rZ97hB,cache=off,format=raw,if=virtio \ -nodefconfig \ -nodefaults \ -nographic \ -m 500 \ -no-reboot \ -no-hpet \ -device virtio-serial \ -serial stdio \ -chardev socket,path=/tmp/libguestfsEjpY0b/guestfsd.sock,id=channel0 \ -device virtserialport,chardev=channel0,name=org.libguestfs.channel.0 \ -kernel /var/tmp/.guestfs-0/kernel.2125 \ -initrd /var/tmp/.guestfs-0/initrd.2125 \ -append 'panic=1 console=ttyS0 udevtimeout=300 no_timer_check acpi=off printk.time=1 cgroup_disable=memory selinux=0 guestfs_verbose=1 TERM=xterm ' \ -drive file=/var/tmp/.guestfs-0/root.2125,snapshot=on,if=virtio,cache=unsafeopen /dev/kvm: No such file or directoryCould not initialize KVM, will disable KVM support[ 0.000000] Initializing cgroup subsys cpuset[ 0.000000] Initializing cgroup subsys cpu[ 0.000000] Linux version 2.6.38-8-generic (buildd@allspice) (gcc version 4.5.2 (Ubuntu/Linaro 4.5.2-8ubuntu3) ) #42-Ubuntu SMP Mon Apr 11 03:31:24 UTC 2011 (Ubuntu 2.6.38-8.42-generic 2.6.38.2)[ 0.000000] Command line: panic=1 console=ttyS0 udevtimeout=300 no_timer_check acpi=off printk.time=1 cgroup_disable=memory selinux=0 guestfs_verbose=1 TERM=xterm [ 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: 00000000fffc0000 - 0000000100000000 (reserved)[ 0.000000] NX (Execute Disable) protection: active[ 0.000000] DMI 2.4 present.[ 0.000000] No AGP bridge found[ 0.000000] last_pfn = 0x1f3fd max_arch_pfn = 0x400000000[ 0.000000] x86 PAT enabled: cpu 0, old 0x0, new 0x7010600070106[ 0.000000] found SMP MP-table at [ffff8800000fd790] fd790[ 0.000000] init_memory_mapping: 0000000000000000-000000001f3fd000[ 0.000000] RAMDISK: 1f2c8000 - 1f3f0000[ 0.000000] No NUMA configuration found[ 0.000000] Faking a node at 0000000000000000-000000001f3fd000[ 0.000000] Initmem setup node 0 0000000000000000-000000001f3fd000[ 0.000000] NODE_DATA [000000001f3f5000 - 000000001f3f9fff][ 0.000000] Zone PFN ranges:[ 0.000000] DMA 0x00000010 -> 0x00001000[ 0.000000] DMA32 0x00001000 -> 0x00100000[ 0.000000] Normal empty[ 0.000000] Movable zone start PFN for each node[ 0.000000] early_node_map[2] active PFN ranges[ 0.000000] 0: 0x00000010 -> 0x0000009b[ 0.000000] 0: 0x00000100 -> 0x0001f3fd[ 0.000000] SFI: Simple Firmware Interface v0.81 http://simplefirmware.org[ 0.000000] Intel MultiProcessor Specification v1.4[ 0.000000] MPTABLE: OEM ID: BOCHSCPU[ 0.000000] MPTABLE: Product ID: 0.1 [ 0.000000] MPTABLE: APIC at: 0xFEE00000[ 0.000000] Processor #0 (Bootup-CPU)[ 0.000000] IOAPIC[0]: apic_id 1, version 17, address 0xfec00000, GSI 0-23[ 0.000000] Processors: 1[ 0.000000] SMP: Allowing 1 CPUs, 0 hotplug CPUs[ 0.000000] PM: Registered nosave memory: 000000000009b000 - 000000000009c000[ 0.000000] PM: Registered nosave memory: 000000000009c000 - 00000000000a0000[ 0.000000] PM: Registered nosave memory: 00000000000a0000 - 00000000000f0000[ 0.000000] PM: Registered nosave memory: 00000000000f0000 - 0000000000100000[ 0.000000] Allocating PCI resources starting at 1f400000 (gap: 1f400000:e0bc0000)[ 0.000000] Booting paravirtualized kernel on bare hardware[ 0.000000] setup_percpu: NR_CPUS:256 nr_cpumask_bits:256 nr_cpu_ids:1 nr_node_ids:1[ 0.000000] PERCPU: Embedded 28 pages/cpu @ffff88001f000000 s84416 r8192 d22080 u2097152[ 0.000000] Built 1 zonelists in Node order, mobility grouping on.
