Hi, altmbr.bin and its variants apparently always boot the first partition (in Syslinux 4.05, but this issue seems older than that). The following example uses parted 3.0: ---------- rm -f flat mkdir mnt truncate -s 20M flat parted -s flat mklabel msdos mkpart primary fat32 1MiB 10485759B mkpart primary ext2 11MiB 100% unit KiB print losetup -o 1048576 -s 9437184 /dev/loop7 flat mkdosfs

xend will not start a domain if one of the block devices is currently mounted elsewhere, but it will not detect if the device is currently attached to a loopback device. I wouldn''t have thought this a problem, provided that the loop device itself wasn''t in use, but it causes all sorts of strange things to happen. My loop device was mounted with the following command

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 all, Since September 2006, I've been using a samba PDC (3.0.20) with tdbsam, to authenticate the users of a school network (90 XP boxes). All the users are able to log in the network from XP boxes. Recently, I've installed a samba client (K12LTSP) in the domain, but, I' ve a problem getting linux client to authenticate against the Samba PDC. After setup all the config files

Hello, I'm trying to boot a dos floppy stored on a disk image which is initially loaded over pxe using memdisk. I've created the disk image as follows: dd if=/dev/zero of=$IMGLOCATION/$IMGNAME bs=$(( 1024 * 1024 )) count=20 LOOPDEV=$(losetup --show -f $IMGLOCATION/$IMGNAME) MAJOR_MINOR=$(ls -l $LOOPDEV|awk '{print $5$6}'|sed 's/,/:/') DMSIZE=$(( $(ls -l

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

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

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

Is there something special about filesystems mounted via the loop device, which prevents Samba from sharing them? I have a small LAN with several PCs on it. It has a few Windows machines, and a Linux machine running Mandrake 10 (kernel 2.6.3), which shares out its root ("/") read-only as "c". (Temporarily, for testing, it is shared with full write permissions, which I know

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Anyone else using CFS on CentOS 4.4 ? I have started using it today (unimportant stuff for now, for testing), and am wondering what are other people experiences with it. I'm using version 1.4.1, rpms kindly provided by Karan on his repository. My main concern is data loss, not security itself. From what I noticed, the strenght of CFS crypto is

Dear all, I'm working on a shell script which is producing a bootable image file. It contains a populated MBR and a single file system (ext4) which again contains a debootstrabed debian stable distribution. Unfortunately, I'm experiencing problems with the bootability of the produced image. When selecting the installed system at the boot prompt, Syslinux responds with something like

# # create image file # dd if=/dev/zero of=hd.img bs=8225280 count=64 losetup /dev/loop0 hd.img fdisk /dev/loop0 Device Boot Start End Blocks Id System /dev/loop0p1 * 63 1028159 514048+ 83 Linux # start sector = 63 # end sector = 1028159 # delta sectors = 1028159 - 63 + 1 = 1028097

Hello Mailing List! A quick question. Has anyone gotten a resize (in my case grown) a Xen DomU disk image? Here is the procedure I have followed: 1.

Hi, xstransact and xswatch are well designed python interface that can be used by third party utils rather than only in xend. But the logging approach here binds xswatch to xend and prevent it from being used by other utils. This patch removes the dependency on XendLogging from xswatch.

hi, This patch remove the runtime download and compile of libconfig package. This package should be pre-installed by user manually. Xen should not do so much dirty things at compile time.

Hi, I am aware that it is impossible to netboot ISO files through pxelinux/memdisk and that there are multiple reasons for not even attempting it (like the operating system which will try to access a physical optical drive through its own drivers anyway, BIOS issues etc.). When people ask questions regarding ISO support in pxelinux/memdisk, they're mostly told to convert the ISO into a
