similar to: Mapping partitions rather than disks into a Libvirt managed KVM guest

centos 6 failed to create entries under /dev for newly created loopback devices. Any one know why? and how to fix/workaround it? The steps to duplicate is pretty simple dd if=/dev/zero of=/tmp/deleteme bs=1M count=100 losetup /dev/loop0 /tmp/deleteme fdisk /dev/loop0?? ## created partitions 1, 2, etc. fdisk -l /dev/loop0? ## confirmed that the partitions do exist mkfs.ext3 /dev/loop0p1 ## failed

I had to create a single floppy image holding the kernel and initrd of SuSe8.0 distibution. When I boot the computer, it first loads the kernel, and starts loading the initrd. After a short while it halts saying ?Boot Failed: please change disks and press a key to continue.? The floppy image is served by a PXE server, so I am not sure if the problem I am facing has anything to do with ?bad

Hey, guys. I have a problem when installing syslinux 4.06, and I'd be grateful if someone could tell me how to solve the problem. My task - to install the bootloader on the virtual machine image. The image contains the MBR and the only partition with the file system ext4. The file system contains all the files for the guest OS. To install bootloader into the image of the guest OS, I use the

How to reproduce: 1. Extract test images from test/data/ldm-data.tar.xz 2. losetup --show -f test/data/ldm-2003r2-simple-1.img Let's assume image file was associated with /dev/loop0 3. ldmtool -d /dev/loop0 create all Result: One LDM volume which contains all required components on the associated loop device will be mapped but application crashes on further attempt to do the same for

Here's the problem. We perform full tar backups of our CentOS 4/5 machines in real-time at regular intervals. And when a disaster happens, we are able to restore those backups onto virgin filesystems, make the /dev/null, /dev/zero and /dev/console devices .. and boot the machine. This has worked well on standalone systems, and also on Xen 3.0.3 guests on CentOS 4.4 machines, where each guest

Hi, I'm trying to build a bootable MSDOS disk and put it on a ISO with floppy and hard disk emulation. I want to use commonly available Linux tools like dd, losetup, mkdosfs, memdisk etc. I have done the following: 1. dd if=/dev/zero of=myImage bs=1M count=50 [ Builds a 52MB image ] 2. losetup /dev/loop0 myImage [Links /dev/loop0 to myImage file ] 3. vi /grub/stage1; %!xxd; [ NULL the partion

Hi, I have potentially found a (minor) bug (or missing feature) in btrfs, but it might be a misunderstanding, so I like to ask here first before reporting in Bugzilla. I have a btrfs file system in RAID1 mode with two missing devices, but I know that all data is still present on the remaining device. btrfs refuses mounting this fs in rw mode (too many missing devices), as it probably just counts

Hello everyone. I'm trying to install CentOS 8 with root and swap partitions on software raid. The plan is: - create md0 raid level 1 with 2 hard drives: /dev/sda and /dev/sdb, using Linux Rscue CD, - install CentOS 8 with Virtual Box on my laptop, - rsync CentOS 8 root partition on /dev/md0p1, - chroot in CentOS 8 root partition, - configure /etc/mdadm.conf, grub.cfg, initramfs, install

Hi guys, I have Xen 3.0.3 installed with yum on Centos 5.1. I''am facing an issue trying to resize the disk image of a centos 4.5 VM. The VM disk size is 50Go and i need to add 150Go. I tried two methods so far : -------------1st method----------------------- dd if=/dev/zero of=<image file> bs=1M conv=notrunc count=1 seek=2500 * losetup /dev/loop0 <image file> * e2fsck -f

hi ya syslinuxerz - i've been slowly working on a making a custom bootable standalone usb-stick with X11 and kde - it's basically builds itself off of a slackware-10.1 server - create a custom initrd.gz ( /dev/ram0 ) http://linux-boot.net/Bootable/InitRD/ - create a custom rootfs.gz ( /dev/loop0 ) http://linux-boot.net/Bootable/RootFS/ - create X11 and kde loopfiles

I've been trying to figure this one out for some time now without success and can't find anyone else with this exact problem, so hopefully there's a guru around here that might be able to point me in the right direction. I've got a copy of Dark Reign I want to play on my netbook. The problem is that I only have a USB CD drive which I don't normally connect, but can for a

Hi! I recently tried to mount a filesystem in RAID1 mode using loopback devices. I followed the instructions at [1]. Here''s exactly what I''ve done: $ dd if=/dev/zero of=raid1_0.img bs=1M count=500 $ dd if=/dev/zero of=raid1_1.img bs=1M count=500 $ mkfs.btrfs -m raid1 -d raid1 raid1_0.img raid1_1.img $ losetup /dev/loop0 raid1_0.img $ losetup /dev/loop1 raid1_1.img $ mount -t

Have been trying some things, but something isn't working at least with using Virtual Box with EFI option. With it off, the cd boots as normal, and works, but with EFI on, it has an error that flashes on screen, and then it drops to a shell prompt. I'm hoping it is just a dumb mistake I am making, and can be resolved. Perhaps I've named the directories incorrectly, or there is a
