Description Rubin Simons 2009-11-18 18:42:58 UTC

Description of problem:
libvirt fails to allow the (temporary) connection of a .iso file
which exists on a samba share to a newly created virtual machine.
It complains about not being able to set permissions.

Because of this, it is not possible to install a new virtual
machine with an OS without copying the iso file to your desktop,
and chmod/chowning the file to what libvirt/qemu expects. This 
is extremely unworkable when you have lots of iso files on a
centralized system.

Since the iso file is not to be considered a part of the emulated
system, I fail to understand why it even tries to chown/chmod the
iso file. It should leave the iso file for what it is. This worked
correctly in Fedora 11.

Version-Release number of selected component (if applicable):
libvirt-0.7.1-15.fc12.x86_64
libvirt-client-0.7.1-15.fc12.x86_64
libvirt-python-0.7.1-15.fc12.x86_64
qemu-kvm-0.11.0-11.fc12.x86_64

How reproducible:
Always. Just have a .iso file on a samba share and try to attach it.

Steps to Reproduce:
1. Create new VM.
2. Try to attach iso on samba share
3. Observe error.
  
Actual results:
[rubin@inden qemu]$ sudo virsh start bomans
error: Failed to start domain bomans
error: internal error unable to start guest: libvir: QEMU error : cannot set ownership on /net/Software/Fedora 12/Fedora-12-x86_64-DVD.iso: Permission denied

Expected results:
Correctly attached iso file to the VM so as to allow installation!

Additional info:
N/A.

Added myself to CC list.

Thanks for the report

This sounds very similar to bug #517304, so I'm going to mark it as a dup of that even though it's about NFS
