New B200 M4 blades can running on Intel v4 processors. You may see discovery issue if your UCSM firmware version lower than 2.2.7c. I hit that problem few days ago when I install a new M4 blade. The FSM hung on 58% a real long time and failed eventually.
Found this link on Microsoft website. Just want to make a notes on my blog. Thanks community!
If you have VMware Workstation and VMware Remote Console both installed on Windows 10 you may see vCenter virtual machine console in vSphere Web Client is opened by VMware Workstation instead of VMware Remote Console. If you see same case your VMware Remote Console may be hijacked. I call it “hijack” since there is no easy way to revert it back.
如果你的Windows 10电脑上装了VMware Workstation和VMware Remote Console，当你在vSphere Web Client里打开运行在vCenter上的虚拟机控制台时，VMware Workstation可能会代替VMware Remote Console自动连接到控制台。恭喜！你的VMware Remote Console被劫持了。这个问题解决起来比较复杂所以我叫它“劫持”。
用vSphere Web Client打开虚拟机的控制台时可以会遇到报错 “Unable to connect to MKS: Could not locate vmware-authd executable“。
You may get error “Unable to connect to MKS: Could not locate vmware-authd executable” when open virtual machine console in vSphere Web Client.
