Yes, you are right. root@sysresccd /mnt/hitachi/test % fdisk -l /dev/loop1 Disk /dev/loop1: 53.7 GB, 53687091200 bytes 255 heads, 63 sectors/track, 6527 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x2b362b35 Device Boot Start End Blocks Id System /dev/loop1p1 * 1 6526 52420063+ 7 HPFS/NTFS I am so used with device nomenclature of harddisks being /dev/hda, /dev/hdb, /dev/sda, /dev/md0, /dev/xvda, etc that it didn't occur to me that the device node of my virtual machine in a logical volume is very simply /dev/loop1 after I have performed the "losetup /dev/loop1 /dev/volumegroup/logicalvolume" step. Thank you very much for enlightening me! Now I can proceed with writing the backup and restore script for my Fedora 11 Dom0 (all partitions using LVM2 logical volumes) and all of my Xen virtual machines (contained in logical volumes). -- Mr. Teo En Ming (Zhang Enming) Dip(Mechatronics) BEng(Hons)(Mechanical Engineering) Alma Maters: (1) Singapore Polytechnic (2) National University of Singapore My Primary Blog: <a href="http://teo-en-ming-aka-zhang-enming.blogspot.com">http://teo-en-ming-aka-zhang-enming.blogspot.com</a> My Secondary Blog: <a href="http://enmingteo.wordpress.com">http://enmingteo.wordpress.com</a> My Youtube videos: <a href="http://www.youtube.com/user/enmingteo">http://www.youtube.com/user/enmingteo</a> Email: <a href="mailto:space.time.universe@gmail.com">space.time.universe@gmail.com</a> Mobile Phone (Starhub Prepaid): +65-8369-2618 Street: Bedok Reservoir Road Country: Singapore <div class="gmail_quote">On Thu, Nov 12, 2009 at 9:38 AM, Roberto Ragusa <<a href="mailto:mail@robertoragusa.it">mail@robertoragusa.it</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">Mr. Teo En Ming (Zhang Enming) wrote: > # kpartx -av /dev/loop1 [...] <div class="im">> But the problem is that I can only backup/clone the filesystems of my > virtual machine within a logical volume.
