Comment 1 Eyal Shenitzky 2020-10-07 10:08:34 UTC

Libvirt contains the fix since version - libvirt-6.6.0-5.el8
So it should be available for testing now.

No code added from our side but we must make sure that this flow works well according to the steps.

Comment 2 Ilan Zuckerman 2020-10-13 08:42:02 UTC

Verified on rhv-4.4.3-8   with   libvirt-6.6.0-6  according to steps from description.
