Please make sure to run as much OST suites on this patch as possible before merging ( using 'ci please build' )

But note that OST is not a way to verify the patch.

Such changes require testing with all storage types we support.

Hey,

I've created a patch[0] that is finally able to activate libvirt's
dynamic_ownership for VDSM while not negatively affecting
functionality of our storage code.

That of course comes with quite a bit of code removal, mostly in the
area of host devices, hwrng and anything that touches devices; bunch
of test changes and one XML generation caveat (storage is handled by
VDSM, therefore disk relabelling needs to be disabled on the VDSM
level).

Because of the scope of the patch, I welcome storage/virt/network
people to review the code and consider the implication this change has
on current/future features.

In particular:  dynamic_ownership was set to 0 prehistorically (as part of https://bugzilla.redhat.com/show_bug.cgi?id=554961 ) because libvirt, running as root, was not able to play properly with root-squash nfs mounts.

Have you attempted this use case?

I join to Nir's request to run this with storage QE.
