Live Migrations No Longer Working After January 2019 Updates

Thanks for the reply Michael

We have found out that the problem is actually caused by the January update (KB4480963 Monthly Rollup) This affects AMD Bulldozer Family 15h, AMD Jaguar Family 16h, and AMD Puma Family 16h second generation microarchitecture one of which our hosts use, 
and is solved, (we must verify) with KB4490512.

However KB4490512 requires a reboot;
We are unable to live migrate between hosts using SCVMM or Failover Cluster Manager although we can cold migrate.
We have 400 plus live VMs over 40 plus hosts and could really do with a solution that would not involve us powering off our VMs

Live Migrations No Longer Working After January 2019 Updates

We have a problem after the January updates (50 plus blades with AMD Bulldozer Family 15h processors) We have 400 plus VMs hosted on our hyper v clusters (Server 2012R2 and SCVMM 2012r2), and after January updates can no longer live migrate. We have put
the KB4490512 update on one of the hosts but it requires a reboot, which in turn would require us to power down our VMs as we are unable to migrate them off now.  Is there/will there be a fix to enable us to not have to reboot the hosts? 
or is there/ will there be a workaround to enable us to live migrate the vms ?

Hopefully there will be as this will cause a lot of business disruption.

Any help would be much appreciated

Regards
