similar to: /dev/loopX not released when domU terminates ?

I have installed Kubuntu 8.04 with xen 3.2 on kernel 2.6.24-16-xen on amd64 hardware. Then I have created a new domU with xen-tools. The domU is using loopback-images. When I try to start the domU it ends with this: Error: Device 51713 (vbd) could not be connected. losetup /dev/loop0 /home/xen/domains/xx/swap.img failed. loopx is raised by 2 for every try. It looks like a classic and simple

In libguestfs we have a few tests that require root privileges and they are skipped by default (normally you should not build or test as root), but you can do this to run them: sudo make check-root In nbdkit I wanted to check that the file plugin works with block devices (this is not tested), and the only way I can sensibly think to do this is using a loopback device and root.

Hi folks, we made an image of a partition by using dd. Original filesystem is ext3 (4k block-size). My colleague was able to mount this image once (using mount with "-o loop"). Since then anytime we try to mount it, it ends in the following error-message: ioctl: LOOP_CLR_FD: Device or resource busy mount: you must specify the filesystem type We also tried to mount it on another system

This is a known issue. It has been fixed in xen unstable. The problem is loop device is not leased after the guest destroyed. If execute "losetup -d /dev/loopX" in domain0, the problem will be solved temporarily. >-----Original Message----- >From: xen-users-bounces@lists.xensource.com >[mailto:xen-users-bounces@lists.xensource.com] On Behalf Of Thomas Karsten >Sent:

Hi I had installed Xen-3.0.4 in Scientific linux 4 (kernel version 2.6.16.33) by following the instructions given in following link project-xen.web.cern.ch/project-xen/xen/howto_slcXen.html I ve created the guest Domain with fedora image of size 2.2GB , disk space as 10GB and the domain started successfully . when i logged into the xm console and checked the disk space its showing only 2.2GB ..

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

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

We run our dom0''s with 128MB of RAM using xen 2.0.6, kernel 2.6.11 for dom0 and domUs, and typically have ~10 domUs per server. All the domU filingsystems are loopback files served from dom0 using the file method. We''ve found that really busy servers sometimes get out of memory problems on dom0. This appears as lots of x-order memory allocation failures with a variable

Otherwise, stack can be corrupted resulting in incorrect runtime behaviour. For example, overriding argc from main().

Hi, I wanted to create a new btrfs fs for my backups. When trying to mkfs.btrfs for that device, I''m getting "error checking /dev/loop2 mount status" With strace I see where the problem is: lstat("/dev/disk/by-id/ata-INTEL_SSDSA2M160G2GC_CVPO939201JX160AGN-par", 0x7fffa30b3cf0) = -1 ENOENT (No such file or directory) The problem is there is something missing

Hi, I have Xen 3.3.1 dom0 on Debian with 2.6.26-2-xen-amd64 kernel and I had to "xm destroy" my domU.

Hi guys, I am having problem with installing Windows 7 RC on Xen. My config file is: WIndows is starting, which i can see in VNC terminal, and it hangs on "Starting windows" screen...

Hi All, I have several Xen virtual machines within logical volumes using LVM2. I did not use disk images for performance reasons. Conventionally, if I want to clone my virtual machines, I have to dd the LV to an image file. But this consumes a lot of time and harddisk space. So, instead of doing that, I want to use losetup and kpartx with my logical volumes, which contain operating systems of

Package: xen-utils-common Version: 4.0.0-1 Severity: normal After upgrading xen-utils-common from 3.4.2-4 to 4.0.0-1, I could not create a guest domain defined with a DRBD file type. The xm create command would fail with "Error: Device 51713 (vbd) could not be connected. Hotplug scripts not working.". After some research I realized the /etc/xen/scripts/block-drbd helper script was
