[Bug 691590] Re: libvirt restore exactly the old ownership of images

[Christian Ehrhardt ]

I upload to a PPA and test against that when doing bigger changes.
Only when everything works there the same thing is uploaded to the -dev release.

I agree to the "many small changes" theory in general, except for things that either:
- a) are used in many other tests (which means breaking these breaks a lot)
or
- b) require a rather intensive testing (then there is an efficiency gain to batch to some extend)

In this case it is even a+b which makes me be careful.
If not for me being away in 10 days for a while I'd not be too concerned as it could be reverted.
You know what, I can throw it in a PPA and if magically everything works fine (after all most tests are automated - it is all the special cases that might happen which make this a real effort) without  hickups I'll consider an earlier upload.

Consider it a favor for your old work :-)
I'll let you know how things turn out ...

Title:
  libvirt restore exactly the old ownership of images

Status in libvirt:
  Fix Released
Status in libvirt package in Ubuntu:
  In Progress

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.
