OS: EL6 - sometimes I use kpartx -a /mnt/.../lvdisk.img to map the partitions and mount them via /dev/mapper/loop0pX After using the disk (unmounting it) I noticed that detaching such mapping via kpartx -d does not result in freeing up the loop devices. Results: System reboots shows that the filesystem where lvdisk.img is...

Hello, here is the second release of kpartx : the shameless perversion of util-linux's partx. As before it : 1) compiles against klibc 2) read partitions table like partx 3) drives the device mapper to present the partitions bdevs Find it at http://dsit.free.fr/kpartx-0.0.2.tar.bz2 This release adds a interesting functionality : it ca...

...ual 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 virtual machines. I can backup the filesystems of a virtual machine in this way: # losetup /dev/loop1 /dev/virtualmachines/windows7-x64 virtualmachines is the name of my volume group. windows7-x64 is the logical volume. # kpartx -av /...

Hello, I''m not able to mount a HPFS/NTFS domU partition. My system: dom0 is on a debian (Lenny) machine, using xen-hypervisor-3.2-1-i386 Xen Hypervisor. domU is a Windows XP machine, that works well. My target is to mount file system domU machine (when domU is not active). In my domU configuration file I have: disk = [''phy:/dev/virtual_machines/xp_disk,hda,w'',

I''ve been using lvm under centos to create the backing store for domUs and although the performance seems acceptable it has some shortcomings. The biggest of which is the LVM bug which prevents me from removing an lv (it says it is still mounted and it definitely isnt). I thought this was just a centos bug but it appears to be evident in debian and ubuntu too and I really can''t

Hi List, slightly OT but i have Xen and Windows running (xen 3.2.0, hvm, win 2k3) on top of a lvm volume. Now i want to delete such a volume but i got the message: $ lvremove /dev/Xen0/Win2kServer Can''t remove open logical volume "Win2kServer" The volume is not in use by any VM, but there is a partition table on it with 8Megs of free space and a ntfs partition. I also got 2

Hi all I want to shrink one of my LVM based domU''s, but don''t quite know how to do it. I have searched the Wiki & HOWTO''s, and they all show you how expand / enlarge a LVM based domU, but not shrinking it. So, I stopped (destroyed) the domU, and then resized it as follows: lvresize /dev/data/cpanel1 -L10GB (It was 100GB), but when I a started it up again, I

domUloader potentially makes my life a lot easier, but from experiments and looking at the code, it doesn''t seem like there is any way to pass kernel command line arguments with it. Am I just missing something? Thanks, John Byrne _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hi, Apparently, guestmount -o allow_other -a "/path/to/raw_file" -m /dev/sda1 "/path/to/mountfolder" is much slower than kpartx -av "/path/to/raw_file" mount /dev/mapper/loop0p1 /path/to/mountfolder (Doing lots of read/write inside the image.) I thought guestmount "only" scripts the above. Seems I was wrong on that. I am currently using libguestfs 1.18.1-1 (because it comes with Debian wheezy/stab...

I have a Windows 2000 domU running in an LVM partition. I need to move it to another host, but none of my other xen servers have lvm or free space to create an lvm. So I''d like to convert it to a sparse img file. The file system in the domU is ntfs. Can anyone suggest how to do this?
