Using a File as a Disk Partition Image
hi!
i encountered a problem when trying this lab 17.1 on the VM...thus is it impossible to create loop partition in a Virtual Machine?
i got this error:
mount: /tmp/imagefile: failed to setup loop device: No such file or directory

i re-take the same labs with a RHEL Virtual Machine with success!
maybe the problem is about the Centos VM i get from lftraining

not enough information. The labs were developed on VMs do that is not a problem. If you want help, post the actual commands you used and the actual output.

I did not see your successful comment. One thing to check is what kernel you are running. Other that that it should make no difference whether it is RHEL and CentOS

#uname -a
Linux CentOS7 3.10.0-123.el7.x86_64
#dd if=/dev/zero of=imagefile bs=1M count=512
#mkfs.ext4 imagefile
#mkdir mntpoint
#mount -o loop imagefile mntpoint/
and for the last commands i got this output:
mount: /imagefile: failed to setup loop device: No such file or directory
#losetup -f give the following output:
/dev/loop0
#losetup /dev/loop1 imagefile
losetup: /imagefile: failed to set up loop device: No such file or directory
that is the issue!

I don't have to debug on a centos VM right now, tbut the message is tell ing you it can't find /imagesfile, not just imagefile. So maybe you are sitting in / instead of wherever you made the imagefile? Try giving the full path to the iamge file like /tmp/imagesfile etc.
