similar to: dump VBR of a VM image's partition

Thank you all for your suggestions! Richard W.M. Jones: > I keep meaning to write a comprehensive "virt-diff" tool. I needed it > myself just yesterday. Most interesting. I guess there are two reasons for creating such a tool: just compare the images (show the diff) and/or check for malicious additions in the other image. Did you consider implementing the former or both? Do

Hi all, Piping in here as someone who has worked on file system and Registry differencing for a few years now. Taking diffs of a storage system is not a straightforward task. Hopefully, this message saves you some re-implementation heartache. In the forensics world, there is a tool called Fiwalk, which enumerates the contents of a file system and its metadata (with some basic data summaries,

Hi! Is it possible to read the MBR of an image and to store it inside a file? (If you want to know what I really want to do: Creating a report on all contents of an vm image. [1] [2] Create the image on two different machines, compare them and see, that there are no important differences besides temporary files.)

Hello, my project still uses VBoxManage but I am inclined to switch to libvirt, if possible, because I like the concept. Some rather unusual commands are used by my project... VBoxManage modifyvm "$VMNAME" --synthcpu on VBoxManage setextradata "$VMNAME" "VBoxInternal/Devices/VMMDev/0/Config/GetHostTimeDisabled" "1" VBoxManage modifyvm "$VMNAME"

Hi, is it possible to convert a bootable raw hdd image including grub (originally created with grml-debootstrap) to a bootable iso somehow? Cheers, adrelanos

In my usb drive with EXT3 filesystem in /dev/sda1 partition, syslinux uses the first sector on /dev/sda1 but EXT3 filesystem doesn't?

For a bootable usb drive, syslinux seems use MBR and VBR to find vmlinuz and ramdisk. And VBR stays in the first sector of partition, 63rd for example. So does VBR conflicts the filesystem on partition?

Hi, Is there any way to change the partition type using python-guestfs? I'm trying to recreate an NTFS partition, but can not change the type to NTFS (7 identifier in frisk) Filesystem from my disk g.list_filesystems() {'/dev/sda1': 'ntfs', '/dev/sda2': 'ntfs’} Fdisk print g.sfdisk_l(device) Disk /dev/sda: 51200 cylinders, 64 heads, 32 sectors/track Units =

Hi, I know btrfs complicates filesystem lists due to the use of subvolumes. However, I just noticed that the root partition itself ends up being listed twice with list-filesystems, inspect-os, inspect-get-roots, etc... I'm seeing this in version 1.26, but haven't found anything directly resolving this in newer versions. These commands all show the partition listed twice as in the

Yes, easily :-) guestfish --ro -a disk.img run : pread-device /dev/sda 512 0 > mbr This will work for any format of disk. Of course for a raw format disk this is just a slower way of reading the first 512 bytes from the raw file. Since

what about just using dd? dd if=disk.img of=mbr bs=512b count=1 On Fri, 2013-11-22 at 16:24 +0000, Richard W.M.

Does anyone know how anaconda partitioning enumerates disk partitions when specified in kickstart? I quickly browsed through the anaconda installer source on github but didn't see the relevant bits. I'm using the centOS 6.10 anaconda installer. Somehow I am ending up with my swap partition on sda1, /boot on sda2, and root on sda3. for $REASONS I want /boot to be the partition #1 (sda1)

Hi. I am running CentOS 4.3 on a small home server just dishing up mail, music etc. to the household. I had been doing irregular backups to a 160GB USB external drive /dev/sda1 mounted as /mnt/backup using tar. Then I read somewhere that dump was better so I tried that after clearing the drive (formatted as ext3). dump -0u -f /dev/sda1 /shared took a while to finish but gave no errors however ls

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I'm working with XenServer 5.5u2, which is basically CentOS 5. I'm having trouble creating a partition. I should still have free space in the extended partition, but it won't let me create any more logical partitions. Is there anything I'm doing wrong or is this a bug in fdisk?

Hello. I can''t start Virtual Machine, have the message: Waiting for root file system ... done. Gave up waiting for root device. Common problems ..... ALERT! /dev/xvda2 does not exist.

This may not be the best forum to ask, but it does seem to be one where it is as likely as anywhere that someone will have dealt with a similar problem. I need to define a procedure for last resort disaster recovery from an incremental file level backup of the root partition (and any others that are critical.) Now it is easy enough to create a raw virtual disk with dd, then to losetup and do a
