What’s New

vCenter Server 6.7 Update 3 supports a dynamic relationship between the IP address settings of a vCenter Server Appliance and a DNS server by using the Dynamic Domain Name Service (DDNS). The DDNS client in the appliance automatically sends secure updates to DDNS servers on scheduled intervals.

With vCenter Server 6.7 Update 3, you can configure virtual machines and templates with up to four NVIDIA virtual GPU (vGPU) devices to cover use cases requiring multiple GPU accelerators attached to a virtual machine. To use the vMotion vGPU feature, you must set the vgpu.hotmigrate.enabled advanced setting to true and make sure that both your vCenter Server and ESXi hosts are running vSphere 6.7 Update 3. vMotion of multi GPU-accelerated virtual machines might fail gracefully under heavy GPU workload due to the maximum switchover time of 100 secs. To avoid this failure, either increase the maximum allowable switchover time or wait until the virtual machine is performing a less intensive GPU workload.

With vCenter Server 6.7 Update 3, you can change the Primary Network Identifier (PNID) of your vCenter Server Appliance. You can change the vCenter Server Appliance FQDN or host name, and also modify the IP address configuration of the virtual machine Management Network (NIC 0). For more information, see this VMware blog post.

With vCenter Server 6.7 Update 3, if the overall health status of a vSAN cluster is Red, APIs to configure or extend HCI clusters throw InvalidState exception to prevent further configuration or extension. This fix aims to resolve situations when mixed versions of ESXi host in a HCI cluster might cause vSAN network partition.

vCenter Server 6.7 adds new SandyBridge microcode to the cpu-microcode VIB to bring SandyBridge security up to par with other CPUs and fix per-VM Enhanced vMotion Compatibility (EVC) support. For more information, see VMware knowledge base article 1003212.
