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
Andrew
