Failed to create /dev/loop0p* entries for partitions inside loopback devices
...y 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 here, the error prompt says that the /dev/loop0p1 doesn't exist!
ls /dev/loop0p*? ## no entries
Please shed a light here, I'm running centos 6.4
Thanks.

Possible to speed up guestmount?
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/stable) and read the FAQ [1] [2], but still have questions.
Seems m...

Strange way to do this, as libguestfs can do all this.

mount: unknown filesystem type 'exfat'
Hello,
Can anyone please tell me whether guestfish can mount exFAT partitions?
I created a full disk image of a drive which contained a single exFAT partition.
Was able to mount it with kpartx/FUSE:
# kpartx -a -v disk.img
add map loop0p1 (252:2): 0 39070078 linear 7:0 2
# mount /dev/mapper/loop0p1 /mnt -o ro
FUSE exfat 1.2.3
# ls /mnt
foo bar baz etc
but not guestfish:
$ sudo apt install libguestfs-tools
$ guestfish --version
guestfish 1.32.2
$ guestfish -a disk.img

Suggestions on building VM disks from scratch

For general performance tips, see this page (I think you've seen it

question on mounting a partition that is in a disk image
How do I mount a partition that is in an image file?
I have a file called centos.img that has 3 partitions in the file.
I need to copy data to the third partition on that image file.
I have seen things about a loop back device (which is fine)
but then it talked about an offset parameter and I dont know what
that is or more importantly what number to use. I hope I'm on the
right track.

Centos 5.5 KVM GRUB / Virtio issue
I have a virtual machine that had been running fine using a RAW disk
image (IDE).
I am in the process of converting this virtual machine to use a single
LVM and virtio. (For LVM backup snapshots and easy resizing purposes (no
LVM within the guest))
I create the LVM and copied all the files from the existing RAW image to
an ext3 under the LVM.
However, I cannot get it to boot. It has to do

Can you convert Windows LVM domU to sparse img file?
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?
Thanks,

img file to physical disk
Hi all.
I''ve got a domU that exists in a sparse file image, I''d like to now use
this on a physical partition (loopback performance issues).
Is there an a easy way to do this ?
