Hello Folks,

As you already know that Microsoft pushed the second update this year for Windows 8.1 and Windows Server 2012 R2.

In this blog post I will list the new updates that applies only for Hyper-V Server 2012 R2.

Here you go 3 bug fixes for Hyper-V:

  • KB2972254: Hyper-V virtual machines cannot be connected to sometimes when TCP connections reconnect in Windows Server 2012 R2.

Symptoms: This issue occurs when a node of a failover cluster is removed from active cluster membership.

  • KB2978101: Windows 2012 R2-based Hyper-V host cluster freezes when virtual machines use shared virtual hard disks.

Symptoms: You have a Windows 2012 R2-based Hyper-V host cluster, or you create Hyper-V virtual machines on the cluster, and then you add shared virtual hard disk files (.vhdx) to the virtual machines.

  • KB2976884: “Access denied error” when Hyper-V Replica Broker goes online in a Windows Server 2012 or Windows Server 2012 R2 cluster.

Symptoms: You have a Windows Server 2012 R2 or Windows Server 2012 failover cluster that is in a domain, and the domain has a disjoint namespace.
You set the primary Domain Name Service (DNS) suffix of the Windows Server 2012 failover cluster to the disjoint domain name.
You create a Hyper-V Replica Broker in the failover cluster, and then you bring the Hyper-V Replica Broker online.

Patch, test, wait and then deploy in Production!!!

Happy Patching Smile
