Description Michael Burman 2021-05-25 06:48:36 UTC 
Description of problem:
[RFE] [SR-IOV] [RHV 4.4.7] Migration should not require downtime as of today

BZ 1688177 was verified as tech preview becasue of the next qemu-kvm known bugs:
BZ 1955666
BZ 1953045

Their fix should be delivered and consumed by RHV in the next el8.4 z-stream and then the SR-IOV migration with minimal down time feature can be fully tested and considered as fully supported. 

We are expecting the qemu-kvm fix will be available during RHV 4.4.7 life cycle.

Note for QE:
Test the feature with the qemu-kvm fix
Comment 2 Michael Burman 2021-06-23 08:43:23 UTC 
Moving to ON_QA as we finally have qemu-kvm-5.2.0-16.module+el8.4.0+11358+3b8f35f7.1.x86_64 available for tetsing
