Title:
  libvirt restore exactly the old ownership of images

Status in libvirt package in Ubuntu:
  Fix Released

Bug description:
  Natty (and it was also the same on Maverick, IIRC).

  When you assign an ISO to a VM, libvirt will take over onwership of
  the ISO. This creates problems if the ISO is updated.

  For example, I am daily updating the Natty server ISOs, and running
  tests on them via KVM (all automated). The ISO updates will fail
  because libvirt chowns them.

  I see no reason for this: libvirt only needs the ISO as input.

  WORKAROUND:
    edit /etc/libvirt/qemu.conf, change 'dynamic_ownership = 0', restart qemu/KVM.
